Financing considerations

How the money usually works here

Construction financing: No true construction loan needed: Keystone finances the build; buyer closes on the finished home.
Rate lock: Rate-lock options depend on the home's completion timeline, the loan program, and current market conditions. We will review the available options once the buyer's expected closing date is confirmed.
Lender credit: Eligible borrowers may receive a lender credit from our branch. The available credit depends on the final loan amount, loan program, and transaction details. Contact Corie for a personalized financing review.
Typical starting price: Low $400s (townhome/villa)
Typical range: $550,000 to $700,000
Upgrades: Base pricing is stronger than most competitors thanks to a robust included-features list; buyers typically upgrade cabinetry, flooring, and lighting.

If the builder owns the lot and delivers a finished home, read what happens between contract and keys. If the house goes up on land you own, start with how construction loans work in Pennsylvania.
