What the payment actually costs
The carrying cost that lenders leave out of the headline number: at 0.69% effective, Idaho sits 38th of 51 states and adds around $230 a month to a $400,000 home, or $2,760 a year.
Homeowners insurance runs about $1,100 a year in Idaho, 42nd of 51 states and below the $1,552 national average. Together, tax and insurance add roughly $322 a month to the payment before you have paid a dollar of principal.
How this fits the rest of your tax bill
The trade-off runs the other way here. Idaho property tax is low at 0.69% — 38th of 51 — but the state does tax income. Owners get off comparatively lightly; the cost shows up on the pay stub instead, which favours buyers with modest incomes and large homes over high earners in small ones.
Housing costs compound with the rate. Idaho runs about 7% below national-average costs, so the same 0.69% rate applies to a smaller assessed value than it would elsewhere. A percentage rate is only half the number that matters; the base it applies to is the other half.
Property tax rates are effective statewide averages; your county assessor sets the actual figure and it varies widely within a state. See our methodology.
