A builder may offer a closing-cost credit, rate incentive, or another promotion when you use a preferred lender. The offer can be valuable, but you should evaluate the full transaction before choosing it.
Compare the same home and loan assumptions
Ask the builder's lender and another lender for figures based on the same home price, down payment, loan type, and expected closing date. Review the interest rate, any discount points, lender fees, monthly payment, cash to close, and how the incentive is applied. A lower rate may have an upfront cost; a large credit may come with different pricing.
Watch the construction timeline
Your projected completion date can move. Ask when a rate can be locked, what happens if construction is delayed, and whether extension charges may apply. Confirm what happens to a lender incentive if you choose different financing. Read the purchase agreement and have your real estate or legal adviser explain deadlines and contingencies.
Build a post-closing budget
New homes can still bring costs for window coverings, appliances, landscaping, HOA dues, and moving. Include property taxes and insurance in the estimated monthly payment. A payment estimate based on incomplete property information should be revisited as closing approaches.
I can help you compare a builder's offer with another mortgage scenario for an Atlanta-area new construction purchase. Bring the incentive sheet and proposed contract terms to the conversation.
