Boise mortgage calculator
A median-priced Boise, ID home at 6.75% over 30 years, with Idaho property tax of 0.63% and $1,400 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$3,701 a month, all in
Principal and interest are $3,088; escrow and PMI add the rest. Over the full term the loan costs $635,571 in interest. Discounted at 5%, buying here has a net present value of $14,089 ($322,983 in today’s dollars).
Within Idaho, Boise is 3rd of the 4 Idaho markets covered here, between Coeur d'Alene at the top and Idaho Falls at the bottom of a 1.53x spread. A state-level median hides most of that.
The price-to-rent ratio here is 21.9 ($529,000 to buy, $2,012 a month to rent), which is high. Renting and investing the deposit is a genuine alternative in Boise, not a fallback position.
Boise carries a premium over the rest of Idaho: a median home here runs $529,000, about 15% above the state median of $460,000. The deposit moves with it, so the same 20% down is $105,800 rather than $92,000.

Where these numbers come from
Idaho medians come from editorial and are refreshed weekly. The Boise figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
