Should a Seller Credit Lower My Cash to Close, or Buy Down My Rate?

A seller credit spent on closing costs is money saved once, at the table. The same credit spent on discount points is a smaller amount saved every month, for as long as the loan lasts. The right use turns on two questions: how the credit compares to your actual closing costs, and how long you expect to keep this mortgage.

Most advice on this stops at "it depends." It does depend. It does not depend on anything mysterious, and both numbers that settle it can be in your hands before you sign the contract.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, NMLS #483943, through C2 Financial Corporation. I'm licensed in fourteen states, and this question usually reaches me on a weekday afternoon, from someone whose agent has just called to say the seller agreed, and who has until the end of the day to say what the money is for.

What is actually being decided here?

The negotiation is over. A dollar amount is on the table, it will appear as a line in the contract, and at closing it gets applied on the settlement statement against what you owe. The money never passes through your hands, so the only decision left is which side of your own costs it lands on.

There are two honest destinations.

Against cash to close. Lender charges, title work, the closing attorney, your initial escrow deposit, prepaid interest. Real money you would otherwise wire. The full anatomy of those charges is worth reading once before you decide anything, because "closing costs" is four different categories wearing one name.

Against the rate. Discount points are a charge paid at closing in exchange for a lower rate for the life of the loan. A temporary buydown is a different animal: it funds a lower payment for the first year or two, then the payment steps up to the note rate. Discount points and temporary buydowns sets out how each one is built.

Whether the seller may contribute at all, and how far, is a separate question with a separate answer. Every program caps contributions, and the cap moves with the program, the occupancy, and the down payment. Whether a seller can pay your closing costs covers that ground. Everything below assumes the credit is agreed and sits inside the cap.

Why does the size of the credit decide most of this?

The first number to look at is not the rate. It is the credit sitting next to your actual closing costs and prepaids. Three cases fall out of that comparison, and they do not have the same answer.

The credit is smaller than your costs. Then every dollar you move to points is a dollar of costs you now cover with your own cash. Points bought this way are bought with your money, and the ordinary break-even arithmetic applies with nothing softening it.

The credit is close to your costs. This is the real fork, and the one the rest of this article is about. Horizon and reserves decide it.

The credit is larger than your costs. A credit cannot exceed your actual costs and come back to you as cash. The surplus is not refunded, not carried forward, not applied to principal. It is lost. What a seller credit can and cannot pay for states that boundary plainly. So the surplus has one useful home left, which is buying the rate down, and the comparison stops being "are points worth it" and becomes "points, or nothing."

That third case is where the most money gets left behind, and it is also the easiest to prevent, because it is a sizing decision made before the contract is signed rather than an allocation decision made after. If you know roughly what your costs will be, you can ask for a credit shaped to them instead of a round number that overshoots.

How do I find my own break-even?

Two lines of arithmetic, and a calculator tape rather than a paragraph.

Extra cash you bring under the points version     $6,000
Monthly payment saving under the points version   $  105
                                                  ------
Months to recapture                                   57

Divide the extra cash by the monthly saving. That is how many months you have to keep this loan before the points version has paid you back. Every month after that is profit. Everything before it is not.

Then run the number against two honest tests.

Will you still have this loan by then? Not the house. The loan. A refinance ends the recapture just as thoroughly as a sale, and a rate move you were happy to see is exactly the thing that would trigger one. What happens if rates drop after you lock is this same question asked from the other side. A five-year recapture on a loan you would refinance at the first opportunity is a five-year recapture you will not finish.

Will the cash be missed? Money spent on points is gone the day you close, and it is gone in the exact week a new house is most likely to ask for something. A modest monthly saving is a poor trade for reserves you do not have. This is not a rule that says never buy points. It is a rule that says count what is left.

What order should I run this in?

1. Get a real cost figure first. Not a national average. Your scenario, your state, your loan amount, with the escrow deposit and prepaid interest included, because those are usually the largest single line and the one people forget.
2. Compare the credit to that figure. You are looking for which of the three cases above you are in. That alone answers a lot of it.
3. Confirm the cap with whoever is writing the loan. A credit above the program limit does not roll into the rate. It gets cut.
4. Ask for the same scenario priced both ways, in writing. One version with the credit against costs, one with as much of it as the cap allows against points. This is a normal request and takes minutes.
5. Do the division. Extra cash over monthly saving, in months.
6. Compare the two on the form, not in conversation. Both versions produce a Loan Estimate, and the sections that move are the ones the lender controls. How to compare two Loan Estimates line by line is the method for reading them against each other.

Where does this decision usually go wrong?

Sizing the credit last. The credit gets negotiated as a round number, then the costs come in underneath it, and the difference disappears. Ask for the number your costs support.

Buying the payment instead of the loan. A temporary buydown shows a lower payment on paper for the first year and reads as the better deal next to permanent points. It is a real tool and it fits real situations, usually an income you can document is rising. What it is not is a lower rate. The rate under it is the note rate, the payment steps up on schedule, and the qualifying is done on the note rate regardless.

Treating the credit as your money. It is a term of the purchase contract, not a balance in an account. It cannot become a down payment, it cannot be paid to you, and if nothing on your side of the settlement statement needs it, it stays with the seller.

Deciding on the rate quote alone. A lower rate always looks better in isolation. The question is never whether the rate is lower, only whether the cash it cost is recovered before you leave the loan.

An illustration

Numbers below are made up to show the mechanism. They are not a quote and not a prediction.

Take a $400,000 loan with $9,000 of closing costs and prepaids, and imagine the same house negotiated two different ways.

A $6,000 credit. Applied to costs, it leaves $3,000 to bring. Moved to points instead, the costs come back in full, so you now bring $9,000, and the payment falls by $105 a month. The extra $6,000 of cash divided by $105 is 57 months, a little under five years. Keep the loan a decade and the points version is comfortably ahead. Refinance in year three and it never gets there.

A $14,000 credit. The $9,000 of costs is covered with $5,000 spare, and that spare cannot be handed to you. Spent on points it lowers the payment for as long as the loan lasts. Left where it is, it returns to the seller. The break-even calculation still exists, but you are no longer weighing points against your own cash, because there is no version of this where the $5,000 lands in your pocket. Both versions cost you the same at the table.

Same house, same buyer, opposite answers, and the rate never entered into it.

Common questions

Can a seller credit be used to buy down my mortgage rate?

Yes. Discount points are a legitimate closing charge, and seller contributions can generally be applied to them, subject to the contribution cap for the program and occupancy. Both the amount and the use should appear in the purchase contract and then on the Loan Estimate, so the lender prices the loan the way the contract describes. Confirm the cap before the number is agreed rather than after, because a contribution above the limit does not convert into anything else.

What happens to a seller credit that is bigger than my closing costs?

The excess is not refunded to you at closing and is not applied to your principal. A credit can only offset costs that actually exist on your side of the settlement statement, so anything above your total closing costs and prepaids simply stays with the seller. That is why sizing the credit against a real cost estimate matters more than negotiating a large round figure, and why an oversized credit is often best pointed at the rate before closing rather than discovered on the day.

Is a temporary buydown better than permanent discount points when the seller is paying?

They answer different questions. A temporary buydown lowers the payment for the first year or two and then steps up to the note rate, which suits a household expecting documented income to rise or planning to refinance early. Permanent points lower the rate for the life of the loan and pay off only if the loan lasts past the recapture point. Neither changes the rate used to qualify the file. The honest test is how long the loan is likely to survive.

Should I ask for a lower price instead of a seller credit?

They are different instruments and not interchangeable. A price cut lowers the loan amount, which moves the payment only slightly because the reduction is spread across the full term, and it never bumps into a contribution cap. A credit is full-strength money available immediately for costs or for the rate, and it is capped. The house also has to appraise at the contract price for a credit to work, since the credit keeps the price higher on paper.

When do I have to decide how the credit is applied?

Earlier than most people expect. The credit amount is a contract term, so it is fixed when the contract is signed, and the use shows up on the Loan Estimate that follows. Changing the allocation later means a revised estimate and, close to closing, a revised settlement statement, which costs time nobody has in the last week. The practical moment to decide is while the contract is still being written, which is also when the cost estimate that should drive the decision is easiest to get.

Price it both ways before you commit

The whole decision comes down to one comparison run twice: the same scenario with the credit against costs, and the same scenario with the credit against the rate. Run your own numbers on the rate tools and bring both versions to the contract conversation, so the allocation is a decision you made with the arithmetic in front of you rather than one made at the closing table.
