Idaho rental property guide
Boise was the poster child of 2020-2022 overbuilding — rents still negative YoY in 2026. Coeur d'Alene, Idaho Falls, and Twin Falls offer more workable economics. Strong landlord law + no state STR restrictions in most markets.
This page gives you the Idaho starting numbers TrueCap uses: the market tier, how landlord-tenant law leans, a typical effective property-tax rate, and HUD Fair Market Rent for each Idaho city TrueCap covers. Use them to set your first assumptions, then verify the parcel before you offer.
Data as of 2026; verify locally before you offer.

HUD Fair Market Rent by Idaho city
HUD Fair Market Rent is the FY2026 housing-program benchmark for the county or metro that contains each city. It is a starting rent for a 2-bedroom or 3-bedroom unit, not a comp for a specific property. Replace it with current leases for the address. When you enter a supported Idaho address, TrueCap starts from the HUD figure and labels it HUD FMR so you can see what you changed.
Three things to verify locally
- Property tax bill. Pull the current bill for the parcel from the county assessor or treasurer, then check how the assessment resets after a sale. A statewide rate is a starting point, not the bill you will pay.
- Rental licensing and permits. Many cities require a rental license, an inspection, or a certificate of occupancy before you can lease. Check the city and county rules for the address before you close, and budget the fees.
- Insurance quotes. Get a written landlord-policy quote for the specific property, including wind, hail, or flood coverage where it applies. Premiums vary by ZIP, building age, and roof, and they decide whether a thin deal still clears.
