Short answer: choose a seller credit when cash-to-close is your main constraint and you have enough eligible closing costs to use it. Choose a lower price when you can fund closing comfortably and want a smaller loan and payment. Compare both on the same lender worksheet—headline dollars alone do not show the tradeoff.
What a seller credit actually changes
A seller credit can reduce eligible closing costs and prepaid items. It does not automatically become cash in your pocket. Under Fannie Mae’s current interested-party contribution rules, credits cannot fund the borrower’s down payment, reserves, or minimum contribution. The credit also cannot exceed actual borrower closing costs without underwriting consequences.
For Fannie Mae loans, the current maximum financing concessions are 3% for a principal residence or second home above 90% LTV, 6% from 75.01%–90% LTV, 9% at 75% LTV or less, and 2% for an investment property. The limit is calculated from the lower of the price or appraised value—not the loan amount. Other loan programs may use different rules, so confirm the exact limit with the lender before writing the offer.
Worked example: $15,000 credit or $15,000 price cut?
Illustrative assumptions—not a quote: 30-year fixed loan, 6.50% rate, 20% down, $18,000 of eligible closing costs in either scenario, no mortgage insurance, and the property appraises at the contract price. Taxes, insurance, HOA fees, points, and future refinancing are excluded because they depend on the property and borrower.
| Item | $900,000 price + $15,000 credit | $885,000 price + no credit |
|---|---|---|
| Down payment | $180,000 | $177,000 |
| Loan amount | $720,000 | $708,000 |
| Eligible costs paid by buyer | $3,000 | $18,000 |
| Down payment + closing costs | $183,000 | $195,000 |
| Monthly principal & interest | $4,551 | $4,475 |
In this example, the credit option preserves about $12,000 of cash at closing but costs about $76 more per month in principal and interest. Dividing $12,000 by $76 gives a simple break-even of roughly 158 months, or 13.2 years. Before that point, the liquidity benefit may matter more; after it, the lower-price option has recovered the upfront difference through the smaller payment. This is a cash-flow comparison, not a forecast of resale value or total investment return.
Three checks before putting the credit in an offer
- Get a lender estimate first. A credit larger than eligible costs can be wasted or treated differently. The CFPB Loan Estimate explainer shows where seller credits reduce Estimated Cash to Close.
- Protect the appraisal math. Raising the price to create a credit can create an appraisal problem. The CFPB specifically warns that a higher price paired with a credit may not appraise. Review the site’s appraisal-gap worksheet before combining a credit with gap language.
- Compare net seller proceeds. A $900,000 offer with a $15,000 credit is economically closer to $885,000 before other terms—but commission, transfer taxes, repairs, timing, and risk still affect the seller’s decision.
When each option usually fits
A credit is often more useful for a buyer who would otherwise drain emergency reserves, especially when the available credit can cover title, lender, prepaid tax, insurance, or permitted rate-buydown costs. A price reduction is often cleaner for a buyer with sufficient liquidity who expects to hold the loan for a long time. CFPB guidance emphasizes that seller-paid costs are not free: buyers may effectively finance them through a higher purchase price. See the CFPB’s mortgage-cost comparison.
A practical offer worksheet
- Ask the lender for maximum allowable credit and estimated eligible costs.
- Request two Loan Estimates using the same rate, term, down payment percentage, and lock assumptions.
- Compare cash to close, monthly P&I, APR, and five-year cost—not just the credit.
- Confirm appraisal exposure and how an unused credit will be handled before signing.
- Keep post-closing reserves for repairs and surprises; do not optimize cash-to-close to zero.
