Short answer: Convert the builder’s preferred-lender offer into a written, apples-to-apples mortgage comparison. Request Loan Estimates for the same property, loan type, down payment and lock period; then compare rate, points, lender charges, lender and seller credits, cash to close, monthly payment, five-year borrowing cost and confidence in the closing deadline. A large credit can be valuable, but it does not prove the linked loan is cheapest.
Freeze the assumptions before comparing offers
Mortgage rates can change daily, so estimates issued on different days can create a false comparison. Give each lender the same sale price, loan amount, down payment, loan program, occupancy, property type and desired rate-lock period. Identify the builder credit exactly: amount, eligible costs, required lender or title provider, expiration, closing deadline and what happens if construction is delayed.
Use the broader OKC new-construction guide to coordinate the contract. This financing decision should also be synchronized with the permit and occupancy-record checklist, because a cheap loan that cannot meet the actual completion date may not solve the buyer’s problem.
Read the credit in context
On the Loan Estimate, compare origination charges, points, services the buyer can and cannot shop for, lender credits and estimated cash to close. CFPB warns that lender credits may be paired with a higher interest rate. A seller or builder credit can reduce cash needed at closing, but the buyer should also test whether the purchase price, options or other terms changed to fund it.
Do not subtract the headline credit from one lender’s fees and stop. Compare total loan costs and the “In 5 years” figure using the same assumptions. Ask each lender for a version with and without points or credits so the tradeoff is visible.

Federal Regulation X addresses affiliated business arrangements. When the exemption applies, the referring party provides a written disclosure describing the relationship and estimated charges, and required-use limits apply. A relationship between a builder and settlement-service provider is not automatically unlawful, and an incentive is not automatically a bad deal.
Save every disclosure and compare the named provider’s actual estimate. Ask who owns or controls each company, which services are optional, which contract benefits depend on using the provider, and what the buyer loses by choosing someone else. Legal questions about a specific required-use arrangement belong with qualified counsel or the appropriate regulator.
Stress-test the construction timeline
New homes introduce completion, inspection, appraisal, repair and certificate-of-occupancy dependencies. Ask how long the rate is locked, who pays an extension, whether the builder credit survives a delay, and whether a revised Loan Estimate may be issued. Keep those answers in writing.
Doug and Ronnie’s practical approach is to compare financing alongside the construction milestone calendar, not as a separate last-minute task. Preserve the new-construction inspection-period guide deadlines even when the preferred lender says the file is moving quickly.

Create columns for each lender and rows for rate-lock date, rate, APR, points, Section A origination charges, lender credit, builder or seller credit, estimated cash to close, total monthly payment, five-year cost, appraisal timing and final approval conditions. Note which figures are estimates and which are fixed.
Choose based on the complete transaction, not the largest advertised number. Before the financing deadline, request corrected disclosures for errors and obtain written confirmation that the selected lender can work with the expected completion date. Loan terms and program eligibility remain subject to the lender’s underwriting.
Document the comparison before selecting a lender
Save each Loan Estimate with the date, rate-lock status and loan assumptions used for the quote. Build a one-page comparison that separates lender credits, builder or seller credits, points, origination charges, services the borrower can shop for, prepaid items, estimated cash to close and the five-year cost shown on the form. Note any upgrade or closing-cost incentive that disappears when another lender is chosen. Then ask each lender to price the same loan amount, down payment, lock period and occupancy scenario on the same day. This does not make the estimates perfectly final, but it makes the tradeoffs visible and gives the buyer a dated record of what was actually compared before signing a lender-selection or incentive acknowledgment.
