How Do You Finance a New Home Build in Idaho?

Financing is the step buyers worry about most and understand least. The short version: you bring the lender, we work alongside them, and most local lenders who do construction lending have done this many times.

Which loan you need depends on how you buy

How a construction loan works

1. Approval. The lender approves you for the full contract price, which includes the lot, the home and your upgrades.
2. During the build. The lender pays the builder in stages as work is completed. You typically make interest-only payments on what has been drawn so far.
3. When the home is done. The loan becomes your permanent mortgage, with full principal-and-interest payments.

One-time close vs. two-time close

• One-time close (construction-to-permanent): one loan and one closing covers the build and the mortgage.
• Two-time close: a construction loan for the build, then a separate mortgage when it's done. Two closings, but you can shop the mortgage at the end.

Contingency in the contract

Construction lenders often require a contingency built into the contract to cover changes or price movement during the build. Your lender will tell you if yours does and how much.

What a local construction loan can look like

One example from a local lender we work with. Idaho Central Credit Union advertises these features on its construction loans:

• Options with as little as 5% down on approved credit
• One-time and two-time close options
• Fixed or variable interest rates
• Build times up to 20 months
• Interest-only payments during construction
• Land equity can count toward the down payment
• Options to stay in your current home while the new one is built

Terms change and depend on your credit, so confirm current details with the lender. Our mortgage calculator page has the loan officer's contact information.

Rates and payments

The rate we show on our homepage was 7.10% as of October 28, 2026. Use the mortgage calculator to estimate a monthly payment from a home price, down payment, rate and term.

How Odyssey works with your lender

• You choose the lender. Most of our buyers use an Eastern Idaho bank or credit union that understands new construction.
• Most Odyssey contracts are fixed price for the base plan plus your upgrades, which is what the lender underwrites.
• Changes after contract are priced and signed as change orders before the work happens, so the lender and you always know the number.
• In rare cases, Odyssey can carry financing if a bank loan falls through. Ask us directly.
