Quick answer
A median-value Idaho home ($446,400) costs about $3,281 a month with 10% down at the 7.24% national average rate. Property tax is light at 0.43% of value, helped by a homeowner’s exemption that removes 50% of your home’s value, up to $125,000, from the tax roll, and Idaho has no real estate transfer tax. Idaho Housing and Finance Association lends up to 8% of the price for down payment and closing costs to households earning up to $170,000.

The Idaho homeowner’s exemption
Idaho’s biggest property tax break is the homeowner’s exemption. If you own and live in the home as your primary residence, the county leaves 50% of the value of the house and up to one acre of land off the taxable value, up to $125,000. Once the county assessor approves it, the exemption stays in place until the home changes hands or stops being your primary residence.
The cap matters once a home is worth more than $250,000. On the median $446,400 home, the dollar cap applies, so the exemption is $125,000, and you pay tax on $321,400 — 72% of the value.
With the exemption counted, Idaho’s effective property tax rate of 0.43% is below the US ratio of 0.89% and the 3rd-lowest of the 50 states and DC. Local levies still set the final bill, so look up the property’s current taxes and confirm whether the seller’s exemption is on it — a new owner must apply.
Two ways to look at an Idaho payment
Idaho’s median home value is above the national median — the 14th-highest in the country — while its median household income of $81,166 is below the US figure. The table compares the median home with the price that income supports under Freddie Mac’s guideline of keeping housing under 30% of gross income.
10% down, 30-year fixed at 7.24%, Idaho’s effective tax rate
| Median home | Price the median income supports | |
|---|---|---|
| Price | $446,400 | $276,000 |
| Principal and interest | $2,738 | $1,693 |
| Property tax at 0.43% | $160 | $99 |
| Insurance at $4.90 per $1,000 (Freddie Mac national average) | $182 | $113 |
| PMI (midpoint of Freddie Mac’s range) | $201 | $124 |
| Monthly total | $3,281 | $2,029 |
The median income supports a price $170,400 below the median value. Buying the median home on these terms takes an income of about $131,200.

Idaho Housing’s down payment and closing cost loan
Idaho Housing and Finance Association (IHFA) offers a second mortgage of up to 8% of the sales price that can pay the down payment, closing costs or both. A few things set it apart:
- Open to repeat buyers. You don’t have to be a first-time buyer.
- Income limit. Household income must be at or below $170,000 — about 2.1 times Idaho’s median household income — and some IHFA loans set lower limits.
- Your own money. You put in at least $500 of your own funds.
- Education. Every buyer completes IHFA’s Finally Home! homebuyer education course.
- Repayment. It is a loan, not a grant. You repay it in monthly payments alongside the first mortgage, so count that second payment in your budget.
On the median $446,400 home, 8% is $35,712. An FHA loan needs at least 3.5% down ($15,624), and closing costs at the low end of the CFPB’s 2%–5% range add about $8,928, so the assistance more than covers both, leaving $11,160 of room. Borrowing the maximum is not always wise — a smaller second loan means a smaller second payment. Compare it with grants and other options in the first-time buyer programs guide.
No transfer tax at an Idaho closing
Idaho has no state real estate transfer tax, so neither side pays a tax based on the price. Closing costs come down to lender fees, title insurance, recording fees, prepaid interest and the first deposits into escrow — on the median home, the CFPB’s typical range works out to $8,928–$22,320. Your Loan Estimate lists the actual figures, and the closing cost calculator gives a state-specific estimate before you apply.

Idaho’s homes are the 5th-newest in the country by median build year, and its owner share is the 8th-highest. Newer construction can mean fewer surprises in the inspection, but rural properties with a private well or septic system deserve their own checks.
