Idaho Mortgage Financing: Property Tax Brackets & PITI Calculations
Calculating a monthly home loan payment in Idaho requires factoring in Principal, Interest, Homeowners Insurance, and local county Property Taxes (PITI).
The Idaho Homeowner's Property Tax Exemption
Under Idaho Code § 63-602G, owner-occupied primary residences in Idaho qualify for the Homeowner's Property Tax Exemption, which exempts up to 50% of the taxable value of the home and up to one acre of land (capped at a statutory maximum index annually, typically ~$125,000).
PITI Monthly Payment Components in Idaho
- Principal & Interest: Standard amortized monthly loan obligation.
- Idaho Effective Property Tax: Averages approximately 0.63% to 0.75% statewide (Ada, Canyon, and Kootenai counties).
- Hazard & Wildfire Insurance: Averages ~0.35% to 0.50% of structural value annually.
- Private Mortgage Insurance (PMI): Applied if putting less than 20% down on conventional loans (0.3% – 1.2% annually).
