Most lenders use two limits. Your housing payment, including principal, interest, property tax, homeowners insurance and any PMI, should stay under about 28% of your gross monthly income, and all of your monthly debt payments together should stay under about 36%. The calculator takes whichever limit is lower, then works backward from that payment to the most expensive home it covers at the current rate.
In White Sulphur Springs, property taxes run about 0.81% of a home’s value each year, based on the Census median tax bill, which counts against the same monthly budget as the mortgage. Each quarter point move in mortgage rates changes the price you can afford by roughly $3,715 for a median income household. A larger down payment, paying down other debts, or a lower rate from a local lender all raise your budget.
