Pre-loaded with real Idaho data: Ada County property tax (0.44%), average homeowners insurance ($2,240/yr), Treasure Valley appreciation forecast (3.5%), and current rent growth (2.0%/yr).

Renting — monthly
Current rent$2,200
Renter's insurance~$15
Rent in year 5$2,429
Total today/mo$2,215
Equity built/mo$0
Buying costs $1,569/mo more out of pocket today. That gap narrows as rent climbs 2.0%/yr — reaching $2,429/mo by year 5 while your mortgage stays fixed.
Idaho homeowner's exemption removes 50% of assessed value up to $125,000 from your taxable assessment — already factored in above. Renters receive none of this benefit.
Renting + investing comes out $45K ahead over 5 years
Over a shorter horizon at current rates, investing your down payment at 7.0% outpaces appreciation gains. Buying typically wins in the Treasure Valley at 6–7+ years — extend your timeline and the math flips decisively.
