Bilt's Housing-only option advertises up to 1.25X on your mortgage. The Flexible Bilt Cash option pays 4% on everyday spending instead, and you keep the card's 2X either way. On a $2,000 mortgage the choice is 2,500 points a month versus $80, which makes the breakeven 3.2 cents per Bilt Point. Here is the whole flow, verified against Bilt's own terms.
The short version: Bilt gives you two ways to earn on a mortgage and they are mutually exclusive. The default advertises the bigger multiplier. I took the other one, because it turns ordinary spending into a currency that pays the mortgage. Everyday purchases earn 4% Bilt Cash on top of the card's points, that Bilt Cash converts into points on the housing payment, those points build Elite Status, and status doubles what Rakuten pays you forever after. The catch that makes it all work: Bilt Cash expires every year, so the only wrong move is letting it sit. Verified against Bilt's Card Offer Terms (July 28, 2026), the Bilt Cash Program Terms, and Bilt's support documentation on August 25, 2026.
Bilt takes mortgage payments the same way it takes rent. From Bilt's own instructions: "Open the Bilt app and go to the Home tab. Select 'Add a mortgage' and search for your servicer. If Bilt supports your servicer directly, you can link your mortgage account and make payments without any additional setup." If yours is not supported, "Bilt provides a dedicated BillPay account — including routing and account numbers — that you add as a payment method in your servicer's portal."
The money movement is worth understanding before you rely on it. Bilt describes it as a card payment that "is processed by your mortgage provider as a standard ACH transfer to your servicer, transaction fee free, and then the funds are debited from your linked bank account within 24 hours." Their guidance is to "allow at least 3 business days for your servicer to receive the payment." Only residential mortgages qualify. Bilt states that "commercial mortgages are not supported at this time."
There is no fee. Bilt is explicit: "Bilt Cardholders are never charged a transaction fee by Bilt to earn rewards on Bilt Housing Payments under either Rewards Option."
This is the part almost nobody explains, and it decides everything else. Bilt's terms define two options, and you are on one or the other:
Housing-only Option is the default. "Earn Bilt Points automatically on Bilt Housing Payments with no transaction fee. Your points multiplier on Bilt Housing Payments (0X to 1.25X) is based on your Everyday Spend Ratio."
Flexible Bilt Cash Option is, in Bilt's words, "the Rewards Option in which the Bilt Cardholder ... may earn 4% Bilt Cash on Everyday Spend and may redeem Bilt Cash to unlock up to 1X Bilt Points on Bilt Housing Payments."
Two things matter enormously here and are easy to miss.
The first: if you do nothing, you are on Housing-only. Bilt states it plainly: "If you do not select a Rewards Option, your Rewards Account will default to Housing-only Option." A cardholder who never opens the setting earns no Bilt Cash on spending at all.
Before you switch anything, read this. The option is not freely changeable, and there is a trap in the first week that can cost you a month of housing points:
"You may select your initial Rewards Option at any time during the seven (7) calendar days following your Account Open Date (the "Selection Period"). During that time, you may toggle freely between Housing-only Option and Flexible Bilt Cash Option. Your most recent selection at the time the Selection Period ends will be your active Rewards Option. Once the Selection Period ends, your active Rewards Option is locked for the remainder of your current Billing Cycle and cannot be changed."
"If during your Selection Period you make a Bilt Housing Payment while your active Rewards Option is Housing-only Option and then set your active Rewards Option to Flexible Bilt Cash Option and do not change it back to Housing-only before the end of your Selection Period, you will forfeit the opportunity to earn any points on that Bilt Housing Payment at the end of your Billing Cycle."
So: if you have already made a housing payment in your first seven days, do not end that week on the Flexible option. After the Selection Period, changes are submitted before the last day of a Billing Cycle and take effect the following one.
The second: you keep earning card points on everyday spending either way. Bilt's own comparison table lists "Bilt Points on Everyday Spend" as Yes under both options. The Palladium's earning structure — "2 Bilt Points ('2X Points') on other Eligible Purchases: You'll earn 2 Bilt Points for each $1 spent on all Eligible Purchases except Bilt Housing Payments" — applies regardless. So choosing the Bilt Cash option does not cost you your everyday points. It buys 4% Bilt Cash on top of them, and the price is what happens to your mortgage multiplier.
Under Housing-only, that 1.25X is not a rate you get. It is the top of a sliding scale set by your Everyday Spend Ratio: everyday spending divided by housing payment, recalculated every billing cycle. Bilt publishes the tiers:
| Everyday Spend Ratio | Multiplier on housing | Bilt's own example ($2,000 housing) |
|---|---|---|
| At least 25%, under 50% | 0.5X | $500 spend → 1,000 points |
| At least 50%, under 75% | 0.75X | $1,000 spend → 1,500 points |
| At least 75%, under 100% | 1X | $1,500 spend → 2,000 points |
| 100% or greater | 1.25X | $2,000 spend → 2,500 points |
Below 25%, the multiplier disappears entirely and you get a consolation prize: "the Primary Cardholder will still earn 250 Bilt Points if one or more Bilt Housing Payments are made on the Card Account in that Billing Cycle."
Read that table again with your own numbers. To earn the advertised 1.25X on a $2,000 mortgage, you must put $2,000 of ordinary spending on the same card every month. Most households with a $2,000 mortgage do not also run $2,000 a month through one credit card. The headline rate is written for someone whose card spending equals their housing payment.
The good news, and it is real: under this option there is no ceiling. "There is no annual or monthly cap on the number of Bilt Points you may earn on Bilt Housing Payment under Housing-only Option."
Both options pay the same points on everyday spending. Bilt's own comparison table lists "Bilt Points on Everyday Spend" as Yes under both. So the question is not what you give up on ordinary purchases. It is what each option adds:
I took the second one because it makes my ordinary spending do two jobs at once, and because the first one grades me monthly on a test I do not always pass.
Run both at Bilt's own example numbers, a $2,000 housing payment against $2,000 of everyday spending, and the default option wins on raw points:
| Housing-only | Flexible Bilt Cash | |
|---|---|---|
| Points on everyday spend | 4,000 | 4,000 |
| Points on the housing payment | 2,500 (1.25X) | 2,000 (1X cap) |
| Bilt Cash earned | none | $80 |
| Bilt Cash spent to unlock those points | none | $60 |
| Left over | 6,500 points | 6,000 points + $20 Bilt Cash |
So at a spending ratio of 100%, Housing-only is 500 points ahead and the choice turns on whether that leftover Bilt Cash is worth more to you than 500 points.
The picture flips as the mortgage grows relative to the spending. The Housing-only multiplier is set by that ratio, so a larger mortgage against the same spending drops you down the tiers: $2,000 of spending against a $5,000 payment is a 40% ratio, which is 0.5X, or 2,500 points. The Flexible side does not care about the ratio at all, because 4% is 4%: that same $2,000 of spending produces $80 of Bilt Cash and unlocks about 2,666 points against a $5,000 payment. That is the case where Flexible pulls ahead, and it is the case I am in.
If your mortgage is small next to your card spending, take the default. If it is large, the arithmetic favours the other side.
Under the Flexible option, a single purchase pays out in two currencies. The Palladium's earning structure gives "2 Bilt Points for each $1 spent on all Eligible Purchases except Bilt Housing Payments," and the Flexible option adds "4% Bilt Cash on Everyday Spend" on the same transaction.
The bonus categories ride on top of the points side, and they are the reason the flat rate is only the floor:
| Where you spend | Points | Bilt Cash |
|---|---|---|
| Everything else (flat rate) | 2X | 4% |
| Bilt Neighborhood Dining | up to 5X | 4% |
| Lyft (accounts linked) | 4X | 4% |
| Hotels via Bilt Travel | 4X | 4% |
| Flights via Bilt Travel | 3X | 4% |
Dining is worth understanding precisely, because "up to 5X" is a range not a rate. Bilt says the bonus at Neighborhood Dining restaurants "varies usually between +2-3X by restaurant for a total of up to 5X and is shown in the Bilt app at the time of your visit." Lyft is "an additional 2X per dollar on eligible rides" once you link the accounts, "for a total of 4X." Bilt Travel adds "+2X on hotels and +1X on flights stacked on top of its 2X base rate."
So a $200 dinner at a Neighborhood Dining restaurant can pay 1,000 points and $8 of Bilt Cash. The 4% never changes with the category, which means the Bilt Cash pile grows off your total spending, not just your bonused spending.
Here is the mechanism the marketing never quite spells out. Under the Flexible option you convert Bilt Cash into points on the housing payment: "every $3 of Bilt Cash redeemed unlocks 100 Bilt Points," up to "a maximum of 1 Bilt Point per $1 of your payment amount."
Taken alone that looks like a poor exchange, and this is where it pays to be careful. Three dollars for a hundred points is three cents a point, which is above what we think a Bilt Point is worth. Two facts from Bilt's own terms decide whether that matters.
The first is that Bilt Cash is not money and does not keep:
"Bilt Cash has no direct cash value and is not redeemable for cash, and you may not request or receive payment of cash by deposit to any bank or other account, ACH, wire, check, money order, ATM withdrawal, or any other cash access method."
"Any Bilt Cash that You have earned during a calendar year will expire at the end of that Year, except that $100 of Bilt Cash will be permitted to 'roll over' to the following Year."
The second is that the mortgage is not the only place it can go, and the alternatives pay better per dollar. Bilt's Bilt Cash Program Terms list face-value redemptions, each with its own cap: a Bilt Travel hotel booking credit of "up to $50 of Bilt cash/month for Blue & Silver members and up to $100 of Bilt Cash /month for Gold & Platinum members" on a two-night minimum stay, plus monthly credits at Lyft, Walgreens and Grubhub, Priority Pass guest passes, and larger annual credits at BLADE, Equinox and Blacklane.
Those are dollar-for-dollar. The housing unlock is not. So the honest ordering is: use the face-value redemptions you would genuinely have spent money on anyway, then send what is left to the mortgage before it expires. Bilt says as much itself, advising members who "consistently earn more Bilt Cash per month than you can redeem against your housing payment" to "consider also using it at partner merchants throughout the year so it doesn't expire unused."
What the mortgage conversion is genuinely good for is the remainder. A Bilt Cash balance you have no real use for is worth three cents a point on the mortgage or nothing in January, and that is a straightforward choice.
Both numbers you need are published, so the arithmetic is fixed rather than estimated. The ceiling is "a maximum of 1 Bilt Point per $1 of your payment amount," and the price is "every $3 of Bilt Cash redeemed unlocks 100 Bilt Points."
Work it for a $5,000 housing payment. The ceiling allows 5,000 points. At 100 points per $3, that is 50 lots of $3, so $150 of Bilt Cash covers the maximum on a $5,000 payment. The same arithmetic on a $2,000 payment gives a 2,000-point ceiling and $60 of Bilt Cash. Three cents of Bilt Cash per point, every time, up to the size of your bill.
| Your housing payment | Points ceiling | Bilt Cash to reach it |
|---|---|---|
| $2,000 | 2,000 | $60 |
| $3,000 | 3,000 | $90 |
| $5,000 | 5,000 | $150 |
Now run it backwards, because this is the number that decides whether the strategy fits your life. Bilt Cash comes in at 4% of everyday spend. To generate $150 in a month you need $3,750 of everyday spending; to generate $60 you need $1,500. So covering a $5,000 payment in full, every month, takes roughly $3,750 a month on the card in ordinary purchases.
If your spending does not reach that, you are not doing anything wrong. You simply convert what you have, cover part of the payment, and the ceiling stops mattering. The conversion is not all-or-nothing: Bilt's stated minimum is "$.03 of Bilt Cash to unlock 1 Bilt Point."
The Palladium credits Bilt Cash on a schedule, regardless of spending. Two separate grants, both quoted from the card offer terms:
"You, as the Primary Cardholder, will receive $200 in Bilt Cash each calendar year ... automatically credited to your Bilt Rewards Account upon Card Account opening date and on January 1st of each subsequent year that your Card Account remains open and in Good Standing."
"$300 Bilt Cash Bonus: You will receive $300 in Bilt Cash upon Account Open Date, separate from the Bilt Points and status bonus."
So a first-year cardholder is credited $500 of Bilt Cash without meeting any spending requirement.
What we will not tell you is what that $500 is worth on your mortgage, because Bilt does not say. The terms describe the housing conversion for Bilt Cash generally, and they describe these grants, but we could not find any published statement confirming that granted Bilt Cash is eligible for the housing-points conversion, or excluded from it. Bilt's Bilt Cash terms note only that "the amount of Bilt Cash awarded for any qualifying activity, the qualifying activities and terms, conditions, and restrictions may vary by program, campaign, or status level." That is not an answer. Until it is, multiplying $500 by the conversion rate would be our arithmetic on an assumption Bilt has not confirmed, and this is not the kind of page to guess on. Check the Bilt Cash section of your own Wallet tab before you count on it.
Two published limits do apply to any conversion, and both matter. The first is a per-payment ceiling: "You may unlock up to a maximum of 1 Bilt Point per $1 of your payment amount." On a $2,000 housing payment that caps you at 2,000 points a month, which is $60 of Bilt Cash. You cannot deploy a large balance in one go.
The second is the expiry already quoted above: Bilt Cash "will expire at the end of that Year, except that $100 of Bilt Cash will be permitted to 'roll over'." Put those together and the constraint is real. A balance larger than twelve months of your own conversion ceiling cannot all be used on housing before it expires, so the surplus has to go to Bilt's other redemptions or it is lost.
Bilt's member tiers run on points earned in a calendar year: "Blue - anyone enrolled in Bilt Rewards with under 50,000 Bilt Points earned. Silver - 50,000 Bilt Points earned. Gold - 125,000 Bilt Points earned. Platinum - 200,000 Bilt Points earned."
The detail that matters for a homeowner: mortgage spending counts toward that. Tier status through Qualifying Points is "based on the level of Rent spend, Mortgage Payment spend and non-Rent/non-Mortgage Payment spend through your Account." So the same mortgage that earns points also climbs you toward status, and status, once earned, is durable: "Once earned, Tier Status remains valid for the remainder of the earning calendar year, all of the following calendar year, and through January 15th of the year after that. For example, if you earn a Tier Status at any point in 2025, you'll keep that status through January 15th, 2027."
There is a second, parallel route Bilt calls the Fast Track, based on dollars spent rather than points earned. Housing is explicitly excluded from that one. Bilt's rule is that you get "the higher of the two statuses."
And the welcome bonus hands you Gold outright for $4,000 of everyday spending in 90 days, which is the fastest version of this available.
There is a gap in the published terms, and it sits exactly where this flow would like to close. Tier Status through the points route is defined like this:
"Tier Status earned through Qualifying Points is based on the cumulative amount of Points earned by you in the current calendar year based on the level of Rent spend, Mortgage Payment spend and non-Rent/non-Mortgage Payment spend through your Account, explicitly excluding Points earned through non-spend related activities, including but not limited to referrals and courtesy Points, Rent Free prize Points, incremental campaign Bonus Points, and Points awarded for marketing activities such as participating in member surveys."
Under the Flexible option, housing points are not earned by a multiplier on spend. They are unlocked by redeeming Bilt Cash. Whether a point unlocked that way counts as a Qualifying Point is not addressed anywhere we could find, in either direction. We are not going to tell you it counts, and we are not going to tell you it doesn't.
The good news is that the payoff does not depend on the answer. Status has a second route that is pure spending, and it is the cheaper one. Silver takes 50,000 points, or $10,000 of eligible spend through the Fast Track, and Bilt applies "the higher of the two statuses." Silver is also the only threshold that matters for the Rakuten benefit below. So the doubled conversion is reachable on spending alone, regardless of how Bilt classifies unlocked points.
This is the part that makes the whole thing a loop rather than a list, and it is worth more than most of the card's printed benefits.
Rakuten can pay your cash back as Bilt Points instead of dollars, and Bilt publishes the rate on its own support page. It is not one rate:
"In general, your conversion rate depends on your Elite Status at the time of your payout date. Blue members: 50 points per $1 in Rakuten cash-back. Silver, Gold, and Platinum members: 100 points per $1 in cash-back."
So Silver status doubles your Rakuten conversion for as long as you hold it. At 100 points per dollar and our 1.8-cent valuation, $100 of Rakuten cash back becomes 10,000 Bilt Points worth about $180. A Blue member doing exactly the same shopping gets 5,000 points, worth about $90.
Now connect it to the mortgage. Housing payments earn points, points earn status, and Silver takes 50,000 points in a calendar year. A $2,000 monthly mortgage generating even 1,000 points a month contributes meaningfully toward that threshold, and the welcome bonus hands you Gold outright for $4,000 of everyday spending. Once you hold status, Rakuten payouts pay double for as long as the status lasts, which by Bilt's terms runs to January 15th of the year after the following one.
Two conditions worth reading twice. The rate is set by "your Elite Status at the time of your payout date," not when you shopped, and Rakuten pays "every three months." So the status you hold on the payout date is the one that counts. And Bilt warns that "limited time promotions or offers may change your conversion rate, so check your Rakuten tab to see what conversion rate you can expect."
None of this makes sense on the mortgage alone. The card is a $495 annual fee: "$495 for Bilt Palladium Cards," plus "$95 per Authorized User." Here is what Bilt publishes against it, and how much of it is genuinely automatic:
The welcome bonus is two separate pieces. "You, as the Primary Cardholder, are eligible to receive: (a) 50,000 Bilt Points; and (b) Bilt Gold Elite Status; and (c) $300 in Bilt Cash." The first two need "Everyday Spend totaling $4,000 or more ... within 90 days." The $300 does not. Bilt credits it "upon Account Open Date, separate from the Bilt Points and status bonus." Note the spend requirement says everyday spend, so mortgage payments do not count toward it.
$200 in Bilt Cash every year, automatically. "You, as the Primary Cardholder, will receive $200 in Bilt Cash each calendar year ... automatically credited to your Bilt Rewards Account upon Card Account opening date and on January 1st of each subsequent year." No enrollment, no spending condition beyond keeping the account in good standing. This is the cleanest benefit on the card.
$400 in hotel credits, in two halves. Worth reading carefully, because the annual figure is not how you receive it: "$400 in hotel credits, to be applied in $200 increments twice a year" — up to $200 between January and June, up to $200 between July and December, on "hotel bookings of 2 nights or more made through the Bilt Travel Portal." A one-night stay does not qualify, and an unused half does not roll forward.
Dining is a range, not a rate. Bilt advertises "up to 5X," and the mechanism is honest if you read it. At Bilt Neighborhood Dining restaurants the bonus "varies usually between +2-3X by restaurant for a total of up to 5X and is shown in the Bilt app at the time of your visit." So it is 2X base plus a restaurant-specific bonus you can check before you sit down, not a flat category rate.
Lyft is 4X, but only after you link. "Link your Bilt and Lyft accounts to earn an additional 2X per dollar on eligible rides. Combined with the Palladium Card's 2X everyday base rate, you earn 4X total." Two accounts, one setting, uncapped.
Bilt Travel bookings stack too: "+2X on hotels and +1X on flights stacked on top of its 2X base rate," which Bilt states as "4X total on hotels and 3X total on flights booked at biltrewards.com/travel."
Rent Day, on the 1st of each month. For Palladium, "4 rewards points (2 base points plus 2 bonus points) for every $1 spent on net purchases outside of Bilt Housing Payments," inside a window that runs "from 12:00 am ET through 11:59 pm PT." The bonus is capped at 1,000 bonus points a month, which by Bilt's own worked example means "it would take $500 in eligible spend to reach the 1,000 bonus point maximum." Two honest caveats: housing payments are excluded from Rent Day, and this promotion has an end date. Bilt's terms say it is "effective March 1, 2026 through January 1, 2027."
And one benefit that only exists on the option I chose. The Point Accelerator requires the Bilt Cash mode: "cardholders must have their rewards option set to Flexible Bilt Cash Option ... Cardholders with their rewards option set to the Housing-Only Option are not eligible."
Everything above describes what I do on a Bilt Palladium Card. That raises a fair question, and the honest answer surprised me: most of this loop does not require the $495 card.
Both Rewards Options are available on all three current Bilt cards, and all three earn on housing payments the same way, up to 1.25X, under the same Everyday Spend Ratio rules. Bilt's Blue Card terms spell out the Bilt Cash rate in the same language as Palladium's:
"Bilt Cash Earning: If enrolled in Flexible Bilt Cash Option, the Primary Cardholder and, if enabled, any Authorized Users can earn 4% back in Bilt Cash on all Everyday Spend."
That is the Blue card. Annual fee $0. So the earn-Bilt-Cash-and-spend-it-on-the-mortgage mechanic is not a premium feature, and anyone telling you that you need the expensive card to run it is wrong.
What the annual fee actually buys is the points side of the card, the annual grants, and the travel credit.
| Bilt Blue | Bilt Obsidian | Bilt Palladium | |
|---|---|---|---|
| Annual fee | $0 | $95 | $495 |
| Authorized user fee | $0 | $50 | $95 |
| Other everyday purchases | 1X | 1X | 2X |
| Bilt partner restaurants | up to 4X | up to 6X | up to 5X |
| Dining or grocery, your choice | Not a category | 3X (grocery to $25K/yr) | Not a category |
| Hotels and flights, Bilt Travel Portal | up to 3X | up to 4X | up to 4X |
| Lyft, after linking | 3X | 3X | 4X |
| Other travel | Not a category | 2X | 2X (via everything) |
| Housing payments | up to 1.25X | up to 1.25X | up to 1.25X |
| Bilt Cash rate under Flexible | 4% | 4% | 4% |
| Annual Bilt Cash grant | None | None | $200 |
| Bilt Travel hotel credit | None | $100 | $400 |
| Welcome bonus | $100 Bilt Cash | $200 Bilt Cash | 50,000 points + Gold status + $300 Bilt Cash |
| Spend required for it | none | none | $4,000 in 90 days |
Bilt states the 4% plainly for the whole lineup in its own announcement: "All three Bilt Cards earn points, earn 4% back in Bilt Cash on everyday spend, and let you pay rent and mortgage with no transaction fee through Bilt." So the rate is not what separates these cards. The points multiplier is.
Two things worth noticing in that table, because they cut against the price order. Obsidian out-earns the $495 card at Bilt's partner restaurants, 6X against 5X. And the bonus categories are published on each card's page rather than enumerated in the Offer Terms PDF, so if a specific multiplier is the reason you are picking a card, confirm it in the agreement you are actually sent.
Bilt also publishes the conversion in round numbers, which is easier to hold in your head than the per-dollar version: "For every $30 in Bilt Cash earned, you can unlock 1,000 Bilt Points when you make rent or mortgage payments, across multiple homes." Their own worked example: a $2,000 rent payment plus $60 of Bilt Cash converts to 2,000 points.
Concede these before arguing anything, because two of them are significant.
The welcome bonus has no spend requirement. Obsidian's terms say the $200 "will receive $200 in Bilt Cash on or about the Account Open Date." Palladium's 50,000 points, Gold status and $300 all sit behind $4,000 of Everyday Spend in 90 days. If you cannot clear $4,000 in three months, Palladium's headline bonus is not a bonus, it is a target you will miss.
Dining is better on Obsidian. 3X on your chosen dining-or-grocery category against Palladium's 2X, and 6X against 5X inside Bilt's partner-restaurant network. If a big share of your spending is restaurants, the $95 card out-earns the $495 one on those meals.
Two things you should know before selecting the 3X category. The non-selected category drops to 1X, and the grocery version is capped: "Your non-selected category will earn 1 base reward Bilt Point per $1 spent." Grocery is capped at $25,000 a year; dining is not capped.
You cannot collect both welcome bonuses. Bilt's eligibility conditions are cumulative across the lineup, so treat this as one choice, not a two-card sequence.
Strip out the hotel credit for a moment, because it is only worth what you would have spent anyway. It requires a booking of two nights or longer through the Bilt Travel Portal, and it does not arrive as one lump. Obsidian's terms grant "credits of up to $50" per half-year, resetting in the first half of each calendar year and again in the second, for "a total maximum of $100 each calendar year." Palladium runs $400 a year on that same semiannual structure. If you do not book portal hotel stays in both halves of the year, that line is zero for you on either card.
That leaves the fee gap at $400, against which Palladium puts up:
Above that, Palladium wins. Below it, Obsidian does, and the dining gap pushes the crossover higher if restaurants are a large part of your spending. My own number sits above it, which is why I carry the Palladium. If yours does not, the honest recommendation is Obsidian, and the loop this article describes still works.
And if you want to test the mechanic before paying anything at all, Blue is $0 with the same 4% and the same housing structure.
Any figure that depends on your own redemptions. We value a Bilt Point at 1.8 cents. That is our number, not Bilt's, and it is a judgement about a 1:1 currency into a partner set we value at 1.63 (World of Hyatt), 1.60 (Avianca LifeMiles), 1.55 (Alaska Mileage Plan), 1.50 (Virgin Atlantic) and 2.20 (Japan Airlines). Most of those sit below 1.8, so the figure leans on the better redemptions being reachable. If you consistently redeem far above that, the arithmetic in Step two shifts and the Housing-only multiplier gets more attractive. That is a claim to test against your own last five redemptions, not a hope.
That this survives contact with a bad month. Everything above assumes you actually put ordinary spending on the card. The engine is the everyday spend; the mortgage is what it feeds.
If your everyday card spending reliably matches or exceeds your housing payment every month, and you consistently redeem Bilt Points well above three cents, the Housing-only option is the better side of this trade. That profile is real. It was not mine, and the monthly re-grading is the part I did not want to manage.
If you will not put ordinary spending on the card, none of this works. The whole flow starts with everyday purchases generating Bilt Cash, and 4% of very little is very little. A mortgage alone, under the Flexible option, earns you the $200 and $300 Bilt Cash grants converted to points and not much else.
And if the mortgage is the only reason you are looking at a $495 card, do the subtraction before you apply. The automatic pieces, $200 in Bilt Cash and $400 in hotel credits used on stays you were taking anyway, cover most of the fee. The rest has to come from spending you were already doing. It is a good card for a household already living inside the Bilt ecosystem, and an expensive one for a household buying it for a single feature.
