Affordability & Mortgage
Income needed assumes a ~32% GDS ratio; weekly is mortgage principal & interest only. Price ÷ income is the home price over the income needed. Fixed reference assumptions so listings compare on equal footing, not a lending decision.

Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
Investor snapshot
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersThe last 5 whole-home leases in Rural King signed at a median of $4,788 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $6,456. The gross yield above is on the asking price, before taxes and upkeep; the cap rate is after them. A finished basement or second suite can push real rent above it. Taxes, fees, and vacancy vary by property, and cap rate is before financing.
