Common questions
What I would want you to understand before choosing
Is a builder incentive free money?
No. It can still be valuable, but it is part of the transaction. Compare the home’s price, the preferred lender’s rate and fees, the outside-lender offer, and nearby comparable sales instead of judging the incentive headline alone.
Why can a closing-cost credit help more than the same price reduction?
A credit can reduce the check due at closing dollar for dollar, up to eligible costs. A price reduction is divided between a smaller down payment and a smaller loan, so its immediate payment effect is usually more modest.
Does one point always lower the rate by 0.25%?
No. One point is always 1% of the loan amount, but the rate reduction varies by lender, loan type, and market. Use the rate and cost on the actual written quote.
What happens if the incentive is larger than my closing costs?
The unused amount may not become cash back. Ask the lender and builder whether it can be reallocated to discount points, permitted prepaids, upgrades, or a price change—and confirm the answer in writing.
Do I qualify using the temporary buydown payment?
Typically, no. For a conforming temporary buydown, the lender qualifies the borrower using the full note-rate payment. The temporary payment is a subsidy, not a change to the note.
What if I expect to refinance soon?
Test a short horizon, but do not assume a future refinance will be available or economical. A permanent buydown can fail to recover its upfront cost if the loan ends before break-even.
Why compare an outside lender if it removes the incentive?
Because a larger incentive does not guarantee a lower total cost. The outside offer gives you a reference point and negotiating leverage. Compare written Loan Estimates issued as close together as possible.
Are all credits permitted for every loan?
No. Limits and eligible uses depend on loan program, occupancy, loan-to-value ratio, and the item being paid. This calculator does not decide eligibility; your lender and settlement professionals must confirm it.
Review the actual offer
Want me to place your builder’s worksheet beside the outside Loan Estimate?
I can help you identify which numbers truly differ and which option best matches your cash, payment, and likely timeline.
Important limitations
Use this as a planning conversation, not an official quote.
Educational estimate. This tool provides a planning estimate based on the information you enter and the assumptions shown. It is not financial, lending, legal, tax, insurance, appraisal, or settlement advice; a credit decision or preapproval; a commitment to lend; a property valuation; or a guarantee of costs, savings, eligibility, or future results.
This is not a lender-issued Loan Estimate. Your lender determines qualification, interest rate, points, mortgage insurance, lender credits, program eligibility, and final cash required. Builder incentives and preferred-lender offers are subject to written contract and loan terms, eligibility, appraisal, contribution limits, available closing costs, and change without notice.
No brokerage relationship is created. Using this tool, requesting results, submitting a form, or contacting Ask A Walker does not by itself create a client, agency, brokerage, fiduciary, or other professional relationship. Any representation, services, duties, and compensation will be described in a separate written agreement signed by the applicable parties.
