How it works

Lenders cap the full housing payment — principal, interest, property tax, insurance — near 28% of gross monthly income, and all debt payments near 36%. In Idaho, property tax at about 0.63% of value plus roughly $1,200 a year of homeowners insurance come to about $336 a month on the median home, and that comes out of the 28% budget before anything goes to the loan. On the median income the housing budget is about $1,736 a month, leaving $1,411 for principal and interest.

Homes in Idaho spend about 45 days on the market on average. Idaho's property tax rate is low and a homeowner's exemption shields part of a primary residence's value, but rapid in-migration to the Boise area pushed prices up faster than almost anywhere else in the country.

Does Idaho's income tax affect how much house I can afford?
Not in the lender's math, which uses gross income. It does affect what's comfortable: Idaho's income tax tops out at 5.30%, so take-home pay is smaller than gross by more than federal tax alone.
