Idaho conventional mortgage: limits, down payment math and the state rules

A conventional loan in Idaho is priced by Fannie Mae and Freddie Mac’s national rules, then shaped by local facts: a $460,000 median, property tax near 0.56%, title company closings, and a baseline conforming limit of $832,750. Here are the numbers and the rules, in that order.

The Idaho conforming limit and where jumbo starts

A conventional loan is conforming when it fits Fannie Mae and Freddie Mac’s limit and their guidelines; in Idaho that limit is $832,750 for a one-unit home in 2026. With 20% down, a purchase up to about $1,040,938 stays conforming; with 5% down, up to about $876,579. The state’s $460,000 median leaves ample room, so a typical purchase here is conforming unless the buyer is in a premium neighborhood. Every Idaho county is in the table below; see conforming loan limits and jumbo loans.

Conforming limits for all 44 Idaho counties

The 44 counties of Idaho split into two groups for 2026: 43 at the $832,750 baseline and 1 FHFA high-cost county (bold in the table) with one-unit limits up to $1,249,125. A buyer who crosses into Teton County gains $416,375 of conforming room over a baseline county.

What a conventional loan costs on the Idaho median

Each row is the same $460,000 Idaho home at 6.5% for 30 years — only the down payment changes. PMI is an illustrative market rate for that down payment; property tax is the state’s rough 0.56% effective rate divided by twelve.

Under 20% down, conventional loans require mortgage insurance until the loan-to-value falls; the next section gives the ${e.nom} timeline. Payment tables at other amounts and rates: mortgage payment tables.

How long you pay PMI here

Mortgage insurance on a conventional loan is temporary. With only the scheduled payments at 6.5%, the Idaho buyer who put 5% down reaches the 80% request point after about 10 years and 4 months and the 78% automatic point after about 11 years and 3 months; with 10% down the request point comes after about 7 years and 11 months. Paying an extra $276 a month toward principal, or asking for cancellation on a new appraisal after two years of appreciation, shortens the clock. The full rules are on how to remove PMI.

The Idaho closing: costs and who runs it

Idaho closings are handled by title companies acting as escrow agents, with no attorney requirement and attorneys rarely involved in a residential purchase. Idaho is a dry-funding state: the title company records the deed of trust with the county recorder and disburses once the lender’s funds arrive, which can be a day after signing. Closing fees are split between the parties by custom and the seller usually pays for the owner’s title policy.

Idaho has no mortgage recording tax, no intangible tax and no real estate transfer tax at all. The county recorder charges a per-document recording fee for the deed of trust and for the reconveyance when the loan is paid off. Idaho is therefore among the cheapest states in which to record a loan. Idaho has no real estate transfer tax and no mortgage tax; recording fees are nominal.

Idaho closings use title and escrow companies; with no transfer tax, buyer costs typically total 2% to 3% of the price, and sellers customarily pay for the owner’s title policy.

Prepayment, spouses and homestead in Idaho

Prepayment. Idaho has no statute that flatly bans prepayment penalties on residential mortgages; the Idaho Credit Code (Idaho Code Title 28, chapters 41 to 46) governs consumer credit terms and disclosure for the lenders it covers, and the Idaho Residential Mortgage Practices Act requires licensees to disclose loan terms accurately. The federal ability-to-repay rule caps penalties tightly and bans them on adjustable or higher-priced loans.

Spouses and title. Idaho is a community property state; Idaho Code § 32-912 requires both spouses to join in any encumbrance of community real property, so a non-borrowing spouse signs the deed of trust unless the home is established as separate property.

Homestead. Idaho’s homestead exemption (Idaho Code § 55-1003) was raised from $100,000 to $175,000 in 2020 and attaches automatically to the owner-occupied home (§ 55-1004), protecting that equity from judgment creditors but not from a deed of trust, tax liens or liens for improvements.

The complete state layer — licensing, predatory-lending limits, disclosures, foreclosure — is on mortgage laws in Idaho.

Frequently asked questions

What is the conforming loan limit in Idaho for 2026?

There is no single Idaho number: 1 of the state’s 44 counties are FHFA high-cost areas in 2026, with one-unit limits between $1,249,125 and $1,249,125 (Teton County); the other 43 use the $832,750 baseline. Above your county’s limit, the loan is jumbo.

When can I cancel PMI on a conventional loan in Idaho?

The request point is 80% of the original value, the automatic point 78% — federal rules, identical in Idaho. With 5% down on the state’s $460,000 median at 6.5%, the amortization schedule alone gets you to 80% in roughly 10 years and 4 months; with 10% down, in about 7 years and 11 months. Paying extra principal shortens both.

Does Idaho add anything to a conventional loan’s closing costs?

Idaho has no mortgage recording tax, no intangible tax and no real estate transfer tax at all. Idaho has no real estate transfer tax and no mortgage tax; recording fees are nominal. Idaho closings use title and escrow companies; with no transfer tax, buyer costs typically total 2% to 3% of the price, and sellers customarily pay for the owner’s title policy.
