Investment Summary
As of 2026, Boise City, ID has a 1.3% cap rate, indicating limited cash flow potential at current prices of $545,631 median.
Boise City is very expensive relative to rents — expect negative cash flow. At $545,631 median home price, Boise City requires significant capital. A 20% down payment alone is $109,126. With 3-bedroom rents around $1,660/month, the 1.3% cap rate tells the story. Cash flow is deeply negative at -$2,315/month with standard assumptions. This market requires appreciation to justify the investment.
At 0.30% on the 1% rule, rents are low relative to purchase prices. You'd need a significant discount from asking price to make the numbers work. DSCR of 0.20 is below 1.0, meaning rental income doesn't cover the mortgage. DSCR lenders will likely decline this market at current prices.
Bottom line: At current valuations, Boise City doesn't make sense for rental investors focused on returns. Look at lower-cost markets unless you have specific local knowledge.
