A seller-funded temporary buydown supplies early payment relief; an equal-dollar price reduction changes the purchase price and loan. Use the calculator below to compare the seller’s cost, buyer payment schedule, cash down, and remaining debt.
A seller credit can address eligible closing costs; a price reduction changes the transaction price and usually the amount borrowed. Their value depends on your cash constraint, financing rules, and expected ownership period. Compare written scenarios using the same seller concession budget.
Ask which problem the concession needs to solve
Start with your constraint. Do you need less cash at closing, a lower ongoing payment, or both? A reduction that modestly lowers the payment may not solve a cash shortage. A credit that preserves cash does not automatically create the lowest long-term borrowing cost.
The seller also evaluates net proceeds, contingencies, and timing. Discuss negotiation strategy with your real estate agent and have the lender confirm the financing treatment before the contract is finalized.
Check usable costs before asking for a credit
Seller contributions have program-specific limits and permitted uses. Under Fannie Mae rules, limits vary with occupancy and leverage, and contributions cannot simply exceed eligible closing costs without consequences for the transaction analysis. Do not treat a percentage ceiling as a promise that the entire credit can be used.
A credit is not an unrestricted cash payment to you. Ask the lender to itemize the eligible costs it would cover and whether any amount would go unused. Review the conventional purchase guide or relevant FHA guide for the financing path being evaluated.
Compare three written versions
Request the base transaction, the negotiated price reduction, and the credit option. Compare down payment, base loan, rate, points, lender credits, insurance, total payment, and cash to close. If seller funds buy a rate reduction, obtain the corresponding actual pricing.
Use the temporary versus permanent buydown guide to distinguish a short-lived payment subsidy from a different note rate. Do not compare the first-year payment on one option with the permanent payment on another.
Keep the comparison realistic
Use a realistic holding period and a common future date for remaining debt. If choosing a credit preserves needed cash, show where that cash will remain. If choosing a price reduction, confirm it does not leave you short on closing funds or reserves.
An appraisal below the contract price can change the loan and cash required. Have the lender update the worksheet when the price, credit, appraised value, or closing date changes rather than relying on an early verbal estimate.
Same concession, different use
Assume a $500,000 price, 10% down, and a $10,000 concession. Reducing the price to $490,000 reduces the assumed down payment from $50,000 to $49,000 and the base loan from $450,000 to $441,000. A $10,000 credit instead keeps the original price and base loan but could cover up to $10,000 of permitted costs, if the program and actual cost amounts allow it. Rates and other costs are not held equal by a real lender merely because this example does.

Common questions
Can the credit cover my down payment?
Do not assume so. Seller closing-cost concessions and borrower down-payment requirements are separate rules.
Is a credit always better if I will move soon?
No. Compare the usable credit, pricing, fees, retained cash, and your likely timeline.
