A median Idaho home costs $446,400 (14th of 51). Borrowing 80% at 7.40% gives $2,727.21 per month once $160.00 of tax and $94.58 of insurance are added to $2,472.63 of principal and interest; at 5% down with PMI, budget $3,367.53.
Homestead exemptions and property tax relief
The homeowner's exemption removes 50% of a primary residence's value, up to $125,000, plus up to one acre of land. Apply with the county assessor; it stays in place until you sell or stop living there. Under House Bill 843, starting in 2026 the exemption is no longer prorated: the full exemption applies for the year as long as you apply by the county's last business day of the year. Lower-income owners can also get the Property Tax Reduction ("circuit breaker").
First-time buyer programs
The Idaho Housing and Finance Association offers down payment and closing cost assistance of up to 8% of the price as a 15-year second mortgage. Buyers generally contribute $500 and complete homebuyer education.
Transfer and recording taxes
Idaho has no real estate transfer tax.
Closing costs to plan for
Buyer costs are title, escrow and lender fees.
When property tax bills are due
Idaho property tax bills go out in late fall. You can pay in full by December 20, or pay half by December 20 and the rest by June 20, and late halves get a 2% charge plus interest. If the 20th falls on a weekend, the deadline moves to the next business day. Escrow accounts usually cover both halves.
Before you buy in Idaho
Apply for the homeowner's exemption as soon as you move in. Since House Bill 843 took effect in 2026, the full exemption applies for the year as long as you file by the county's last business day of the year. If you apply after the second Monday in July, you get it as a tax cancellation. Owners 65 and older, disabled or widowed, with 2026 income after medical expenses of $40,030 or less, can also apply for the Property Tax Reduction in 2027.
