## 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.

> **Tip: Apply as soon as you move in**
>
> The exemption is not automatic for a new owner. File with the county assessor once the home is your primary residence; the [property tax guide](https://mortgage-math-us.com/blog/how-property-taxes-change-your-payment/) shows how a change in the bill moves your escrow payment.

## 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.

> **Worked example: 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](https://mortgage-math-us.com/loan-types/fha-loans/) 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](https://mortgage-math-us.com/first-time-buyers/programs/).

## 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](https://mortgage-math-us.com/tools/closing-cost-calculator/?state=ID) gives a state-specific estimate before you apply.

## Idaho’s housing stock and ownership

*Idaho compared with the US (Census ACS 2024 1-year)*

| | Idaho | United States |
|---|---:|---:|
| Median home value | $446,400 | $360,600 |
| Median household income | $81,166 | $81,604 |
| Effective property tax rate | 0.43% | 0.89% |
| Median gross rent | $1,384/mo | $1,487/mo |
| Median owner costs with a mortgage | $1,769/mo | $2,035/mo |
| Median year built | 1993 | 1981 |
| Homes lived in by their owners | 71.7% | 65.3% |

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. If you are weighing whether to keep renting, the [rent vs buy calculator](https://mortgage-math-us.com/tools/rent-vs-buy-calculator/?state=ID&price=446000&rent=1384) opens with Idaho’s median price and rent.
