New Construction vs. Resale: Financing Differences Every Buyer Should Know

Buying a brand-new home sounds straightforward — but the financing process is meaningfully different from purchasing an existing resale property. Understanding these differences protects your interests and can save you significant money.

Builder Financing: The Incentive Trap

Most national and regional builders have a preferred or captive lender. They will offer incentives — closing cost credits, upgrades, rate buydowns — to use their lender. These incentives are real and can be valuable. But they do not mean the builder's lender offers the best overall deal.

Before committing to a builder lender, get an independent quote. The incentive may be worth it — or the rate and fees may be unfavorable enough to negate it. You have the right to use any lender you choose on most new construction transactions.

Extended Rate Lock Challenges

New construction can take six to eighteen months to complete. Standard rate locks run 30 to 60 days. This creates a challenge: how do you protect your rate during a long build period?

Options: Extended rate locks available from many lenders for 90 to 360 days — typically at a cost or with a float-down provision. Float-down options allow you to lock now but capture a lower rate if market rates improve before closing. Some builders lock rates through their captive lender programs.

What Changes Between Contract and Closing

Unlike a resale where your loan is processed against an existing appraised property, new construction loans close against a just-completed home. The appraisal is done based on plans and comps — and if the builder raises prices or makes changes during construction, a re-evaluation may be needed.

Contract-to-Close Timeline Management

New construction closings frequently slip. Communicate proactively with your lender about timeline updates. A rate lock expiration during construction delays can be costly — understand your lock expiration terms and extension options from the start.
