Buying a home in Idaho
Lenders qualify Idaho buyers on gross income, but the budget that actually pays the mortgage is net of state income tax that reaches 5.30% at the top — a few percentage points of headroom that a pre-approval letter quietly assumes you have. Property tax adds a second, permanent layer at roughly 0.58% of assessed value per year.
A buyer earning $100,000 with $600 monthly recurring debt, 20% down, and a 6.5% 30-year fixed mortgage can typically afford a home up to about $400,122.72 in Idaho, with an estimated monthly housing cost around $2,333.33. The 2026 median single-family home price in Idaho is around $500,000.
The 0.58% property tax used here is a statewide effective average — actual bills are set at the county and city level and can differ substantially within Idaho. Verify with Idaho State Tax Commission (https://tax.idaho.gov/taxes/income-tax/individual-income/individual-income-tax-rate-schedule/) and the county assessor before setting a price ceiling.
Idaho home affordability — FAQ
How much house can I afford on $60K in Idaho?

How much house can I afford on $150K in Idaho?

That breaks down to about $3,034.86 principal & interest, $290.09 property tax, and $175.05 insurance per month.
What is the property tax rate in Idaho?
Idaho's effective property tax rate is approximately 0.58% of assessed home value annually. That is among the lowest in the country — only Hawaii (~0.28%) and Alabama (~0.39%) are lower. On a $500,000 home, expect roughly $2,900 per year in property tax.
What is the median home price in Idaho?
The 2026 median single-family home price in Idaho is around $500,000. With 20% down that means a down payment near $100,000 and a financed amount of about $400,000. Prices vary widely by metro — coastal and urban areas typically exceed the state median by 30%–60%.
Is Idaho good for first-time homebuyers?
Idaho state income tax reduces take-home pay, which lenders factor into debt-to-income ratios. Property tax at 0.58% is a low recurring cost. Idaho first-time buyers may qualify for state-administered down-payment-assistance programs through the state housing finance agency.
What's the 28/36 rule and how does it apply in Idaho?
Lenders typically cap front-end DTI (housing payment / gross monthly income) at 28% and back-end DTI (housing + all debt / gross monthly income) at 36%. In high-property-tax states like Idaho (~0.58% property tax), the front-end ratio binds sooner because property tax and insurance can push monthly housing 25%–35% above pure principal & interest. Use the comfortable, stretch, and maximum ranges above to gauge how aggressive your budget is.
Can I afford more house in Idaho or Nevada?
On the same $100,000 income, 20% down, 6.5% rate, good credit profile, the estimated max home price is $400,122.72 in Idaho vs $403,002.19 in Nevada. Nevada allows about $2,879.47 more purchasing power — driven mainly by differences in state income tax (affecting take-home) and property tax rates.
