The builder’s preferred lender, and the incentive attached to it
Builder incentives have gotten large — $12,000 to $20,000 is now ordinary where $5,000 used to be. The incentive is real money and it is yours to use. What decides whether you keep it is where it lands. There are only three places it is allowed to go, and they do not hold their value equally if you refinance. Here is the arithmetic, and how to put the two offers on one sheet.
Sometimes the builder’s lender is the best deal on the table.
That needs saying first, because most of what is written about this topic starts from the opposite assumption. An affiliated lender that prices competitively and hands you $15,000 is a good outcome, and you should take it. I have sent clients into a builder’s lender and told them it was the right call.
What has changed is the size of the number. A decade ago the incentive was a few thousand dollars and the affiliated lender’s rate was usually within shouting distance of the market. Today the incentive can be $20,000 and the rate can be half a point off. Those two things move in opposite directions, and at that scale the comparison stops being obvious and starts being arithmetic.
Two things are true regardless of which way your numbers come out:
- You cannot be required to use them. Federal settlement rules prohibit anyone making a referral from requiring the use of a particular provider. The narrow exception that does exist runs to a lender requiring an attorney, credit reporting agency or appraiser of its own choosing to protect its own interest. There is no exception that lets a seller require you to use its affiliated lender.
- The incentive itself is lawful and normal. A discount or incentive offered to you for doing business with a company is treated differently from a fee paid between two companies for sending business. The rules on that are settled, and nobody is doing anything improper by offering you money.
So the question is not whether to be suspicious. The question is what the incentive is worth after it lands, which is a number you can compute.
An incentive has exactly three destinations, and cash is not one of them.
This is the part that surprises people, and it explains almost everything about how these offers are structured. Money that comes from the seller side of the transaction is an interested party contribution, and agency rules are specific about what it may pay for. It may pay closing costs, prepaid items and escrow funding, and up to twelve months of HOA dues. It may buy down your rate.
It may not fund your down payment, it may not fund your reserves, and it cannot be handed back to you as cash at closing. Any amount left over after your actual closing costs is treated as a sales concession and deducted from the sales price for loan-to-value purposes — which can quietly move you into a worse pricing bucket rather than into your pocket.
So the whole game is which of the three destinations the money goes to, and how much of it you still have if your plans change.
And there is a cap on the total
The contribution limit is set by occupancy and loan-to-value, and it applies to everything from the seller side combined:
| Occupancy | Loan-to-value | Cap |
|---|---|---|
| Primary or second home | Above 90% | 3% |
| Primary or second home | 75.01% to 90% | 6% |
| Primary or second home | 75% or below | 9% |
| Investment property | Any | 2% |
FHA runs a flat 6%. VA allows 4% in seller concessions, and a builder-funded temporary buydown counts against it.
Run this one before you set your down payment. On a $500,000 home with 10% down you are at 90% loan-to-value and the cap is 6% — $30,000, so a $20,000 incentive fits comfortably. Put 5% down instead and you are above 90%, the cap drops to 3%, and the ceiling becomes $15,000. The same incentive is now $5,000 over the line. That makes your down payment a financing decision as much as a cash decision, and it is easier to settle before the contract than after.
When the lender is affiliated with the seller
A lender is normally not an interested party, and a lender credit is normally neutral. That changes when the lender is affiliated with the seller. Agency guidance is explicit that where the lender is, or is affiliated with, an interested party to the transaction, its incentive is treated as a sales concession.
Practically: a credit from the builder’s own lender counts against the same cap as the builder’s money, not on top of it. If you are being shown a builder incentive and a lender credit as two separate wins, they are sharing one ceiling.
The three destinations do not hold their value equally.
If you keep the loan for thirty years, this section does not matter much — everything gets used eventually. It matters if there is any real chance you refinance in the first few years, which on a house bought at a high rate is a chance most buyers are counting on.
| Where the money went | If you refinance at 18 months | Value kept |
|---|---|---|
| Real closing costs | Spent, but on costs you were going to pay anyway | All of it |
| Prepaid escrows and reserves | Your money, in your account, paying your bills — and the balance is refunded when the loan pays off | All of it |
| Temporary buydown | Consumed month by month as payment relief you actually received; the unspent balance is credited at payoff | All of it |
| Permanent discount points | You bought thirty years of a lower rate and used eighteen months of it | Roughly a third |
The escrow line is the one worth sitting with. Funding your tax and insurance escrow is not a fee — it is your own money moving into your own account, and it comes back to you when the loan pays off. How escrow actually works covers the mechanics. Directing incentive money there is the closest thing to keeping it in cash that the rules permit.
The points line is the one that costs people money, and it is the destination the affiliated lender has the most reason to steer toward. That is not a conspiracy — it is arithmetic. Real closing costs and prepaids on a typical file might absorb $16,000. If the incentive is $20,000, points are the only sink large enough to take the rest without it spilling into a sales-price reduction. The structure produces the recommendation.
The same $20,000, on one file.
The setup
A $500,000 new build, 10% down, a $450,000 loan at 90% loan-to-value. The affiliated lender quotes 6.875%. An outside quote comes back at 6.375%. The builder incentive is $20,000, conditioned on using the affiliated lender.
Principal and interest at 6.875% is $2,956 a month. At 6.375% it is $2,807 — a difference of $149 a month, or $1,785 a year, with no incentive attached to it.
What the real costs absorb
Lender, title, recording and appraisal, about $6,500. Prepaid interest for fifteen days, $1,271. Twelve months of homeowners premium, $2,400, plus three months of insurance escrow, $600. Six months of property tax escrow, $4,000. Twelve months of HOA dues, $1,200, which is the maximum the rules allow an interested party to pay. That is $15,971.
Which leaves $4,029 with nowhere neutral to go
It cannot come back to you. Left as an unapplied concession it comes off the sales price, and $450,000 against an adjusted $495,971 is 90.73% — over the 90% line, into a different pricing bucket and a different contribution cap. So it goes to points, which is the one remaining destination.
This is why the buydown conversation happens. It is not the lender being greedy. It is the only legitimate place left for the money once real costs are covered — and it is also the destination that survives a refinance worst.
What the points actually buy, and what happens if you refinance
Assume a typical day where one point buys about a quarter percent. On a $450,000 loan a point is $4,500.
Permanent points, held versus refinanced
$12,000 to points is 2.67 points, roughly 0.667% off, taking 6.875% to about 6.208%. That saves $198 a month, and it breaks even at 61 months — just over five years.
Refinance at eighteen months and you received $3,557 of the benefit. The other $8,443 stays with the lender. There is no proration, no refund and no provision for one anywhere in agency guidance, because points are consideration earned at closing rather than money held on your behalf.
The ratio holds at any size. At eighteen months you keep about 30% of what you spent on points; at twenty-four months, about 40%. The break-even is five years, so a plan that involves refinancing sooner than that is a plan that gives most of the money away.
A 2-1 temporary buydown, same loan
Year one at 4.875% pays $2,381 instead of $2,956 — a subsidy of $6,897. Year two at 5.875% pays $2,662, a subsidy of $3,531. The escrowed deposit is $10,428.
Pay the loan off at month eighteen and $8,662 has been consumed as payment relief you actually received, and $1,766 is still sitting unspent in the account. Nothing is stranded. You either used it or it is credited back.
This is the inversion, and it runs against the usual advice. Permanent is normally described as the better value because it lasts. It lasts only if you do. On a file where a refinance is genuinely likely, the temporary buydown is the one that holds its value and the permanent points are the one that does not.
Neither of those is a recommendation on its own. If you are buying your last house and never refinancing, points at a five-year break-even are perfectly sound and the temporary buydown is the weaker choice. The decision turns on how long you keep the loan, which is your call and not mine. How to decide on points runs that break-even generally, and the discount points calculator will do it on your numbers.
Who funded the buydown decides where the leftover can go.
A temporary buydown is not a rate. It is a deposit sitting in a segregated account, released each month to make up the difference between what you pay and what the note requires. What a temporary buydown really is covers that in full. Because the money is held rather than spent, there is always a balance if the loan pays off early — and the question of whose it is has a written answer.
Agency guidance says that if the mortgage is paid off before the funds are exhausted, they are credited to the payoff amount, or returned to the borrower or the lender as specified in the buydown agreement. VA is stricter and not optional: remaining funds must be applied to the outstanding indebtedness.
Two things follow from that, and they are the practical ones:
- The seller or builder is not on the list. Money a builder contributed to a buydown does not go back to the builder. It goes to your payoff, to you, or to the lender.
- A lender-funded buydown can go back to the lender, and that is the agreement working as written rather than anything going wrong. I have had a file where the unused balance would have returned to the lender that paid it in, which is exactly what the guidance contemplates.
The clause worth reading before you sign
The buydown agreement form in common use triggers on the property being sold and the mortgage being prepaid in full. A rate-and-term refinance is a prepayment without a sale — which is to say the standard form does not squarely address the situation you are most likely to be in.
The agency language is broader and governs a loan sold to an agency. But the document that binds your particular loan is the buydown agreement in your closing package, and it is two pages. Ask for it before closing, not at the table, and read the payoff paragraph. That is the whole diligence item.
One thing you are not exposed to. Lenders do carry early payoff provisions that claw back compensation if a loan pays off quickly — typically within 180 days. Those bind the originator, not you. There is no borrower penalty attached, and no agency loan carries a prepayment penalty. The affiliated lender has a real business reason to discourage a fast refinance, and it is worth knowing that the reason is theirs rather than a cost to you.
Separately, and in your favor: points paid by a seller or builder on a purchase are generally deductible by the buyer, who reduces basis by the same amount and treats them as if paid personally, subject to the conditions in the IRS guidance on points. Whether it helps you depends on whether you itemize, and it is a question for your tax preparer rather than for me.
The incentive has to be optional, and it has to be a real discount.
The settlement rules set three conditions on a package discount of this kind. It must be optional to the purchaser. It must be a true discount below the prices otherwise generally available. And it must not be made up by higher costs elsewhere in the settlement process.
The first two are easy to check. The third is the one that is genuinely hard to evaluate from the outside, because it requires knowing what the affiliated lender’s pricing would be without the incentive attached — which is exactly the thing an outside quote tells you.
The rule that was written, and then withdrawn
In November 2008 the federal regulator finalized a rule redefining required use to reach any situation where access to a discount, rebate or other economic incentive was contingent on using a referred provider. That definition would have prohibited this structure outright.
The homebuilders’ trade association sued the following month. The rule was suspended in January 2009 and the revised definition was withdrawn in May 2009. An advance notice in June 2010 described complaints that buyers were committing to a builder’s affiliated lender in exchange for construction discounts without time to shop, and that the affiliated lender then charged costs or rates that were not competitive. Nothing was ever finalized.
The practice is lawful today. It is not lawful because a regulator examined it and concluded it was harmless. That is worth holding in mind as context, not as an accusation about any particular builder or lender.
One more mechanical point: the incentive has to be disclosed to the appraiser, and the appraisal must report it — expressly including below-market-rate financing. An incentive that does not appear anywhere in the file is a problem for the loan, not a favor to you.
Get one outside quote and put both on the same sheet.
That is the entire method. It costs you nothing, it takes a day, and it is the only way to answer the question the rules themselves care about — whether the discount is real or is being made up elsewhere.
Four things to line up side by side:
- The note rate on each, at the same points. Not the payment, and not the buydown year-one payment. The note rate with the discount points stated separately, so you are comparing the same thing twice rather than two different things once.
- Where the incentive lands, line by line. Ask for it itemized: how much to closing costs, how much to prepaids and escrows, how much to points. That single question tells you more than any other.
- Total cost over the years you actually expect to be in the loan. Not thirty years, unless you mean thirty years. If you think you refinance inside three, run it at three.
- What happens to the money if you leave early. Points are gone. Escrows come back. Buydown balances are governed by the agreement. Now you know which is which.
If your plan involves refinancing, price the refinance now rather than assuming it. On the numbers above, refinancing at eighteen months from 6.875% to 6.375% saves about $144 a month on the remaining balance. That is a real improvement and it is also not a certainty — rates may not cooperate, and a refinance you were counting on and did not get leaves you holding the note rate. Treat it as a goal, not a guarantee, and make sure the file works if it never happens. What a no-cost refinance really is explains how the costs get covered when the time comes, and the break-even calculator will price it.
A few things worth handling early on a new build regardless of which lender you use. Your rate lock has to survive the construction timeline, and extended locks cost something. Your first tax bill will not be your real tax bill, which changes the escrow math above more than anything else on this page. You are almost certainly buying into an HOA in a planned development, and the dues go into your qualifying payment. And if the appraisal comes in under contract, the negotiation runs differently than on a resale. The construction and new-build guide collects all of it.
I have an interest here, and you should know what it is.
I am a broker. If you use the builder’s lender, I am not on the file. So read everything above knowing that, and check it against the outside quote rather than against my word.
What I will tell you is how this actually goes. Years ago the builder incentive was small enough that I could beat it on price — I would price with a lender credit, come back half a point better, send the client an estimate, and the builder would match it. The client got a better deal and I got nothing, which is a fine outcome and not a business.
The incentives got big enough that I cannot match them, and that changed the advice rather than ending it. When the incentive is $15,000 or $20,000, take the incentive. The useful conversation is not whether to use it. It is where it lands, whether the file still works if rates never improve, and what the loan looks like in two years.
That conversation is free and it does not require you to do anything with me. Send me the builder’s worksheet and I will put it next to a real quote and show you both. If the affiliated lender wins, I will tell you that, and it happens.
Send me the builder’s worksheet and I will run it both ways.
Whatever the preferred lender gave you — the estimate, the incentive amount, the buydown structure. I will put it beside an outside quote on one sheet, at the same note rate and the same points, with the total cost over the years you actually expect to be there. You make the call from there.
