Types of mortgage interest rates

Not every rate you see quoted is the same product. Here is how the common options differ when you are building rather than buying.

30-year fixed rate

One interest rate locked for the life of the loan, spread over 30 years for the lowest possible monthly payment.

Best for
Buyers who want payment certainty and plan to stay in the home long term.
Watch out
You pay substantially more total interest than on a shorter term.

15-year fixed rate

Same fixed-rate certainty on a shorter schedule, typically about 0.6–0.9 points below the 30-year rate.

Best for
Move-up buyers with strong equity from a prior sale who want to be debt free sooner.
Watch out
Monthly payments run roughly 40–50% higher than a 30-year term.

Adjustable rate (ARM)

A fixed introductory rate for 5, 7, or 10 years, then periodic adjustments tied to an index plus a margin, within caps.

Best for
Buyers confident they will sell or refinance before the first adjustment.
Watch out
After the intro period your payment can rise at every adjustment up to the lifetime cap.

Construction-to-permanent

Interest-only draws during the build, then a single closing converts the balance to a permanent mortgage.

Best for
Anyone building a new home with an HBA member builder rather than buying existing.
Watch out
Rates usually price above a comparable purchase loan; ask how and when the permanent rate is set or locked.

FHA / VA / USDA

Government-backed loans with lower down payments and more flexible credit standards; VA and USDA can reach 0% down.

Best for
Buyers with limited down payment, veterans, or rural Preble/Fayette County sites.
Watch out
Mortgage insurance or funding fees add to the effective cost even when the note rate looks low.

Jumbo

Loans above the conforming limit, priced by portfolio lenders and often near or slightly above conforming rates.

Best for
Higher-value custom builds in Dayton and the Miami Valley.
Watch out
Expect larger reserves, a bigger down payment, and stricter documentation.

Rate buydown (points / builder buydown)

Paying discount points up front — sometimes funded by the builder — to lower the note rate permanently or for the first 1–2 years.

Best for
Buyers in a high-rate market who want a lower payment while they wait to refinance.
Watch out
A temporary 2-1 buydown resets upward; qualify at the full note rate, not the teaser payment.
