30 year fixed at 6.95 percent, the Freddie Mac weekly average for September 17, 2026, three percent down with mortgage insurance, Williamson County property tax at the 2026 county rate of $1.30 per $100 on the 25 percent Tennessee residential assessment ratio, and homeowners insurance at the county average. A home inside a municipality carries an additional city rate on top, so these figures are the favourable case. The county’s cheapest new-construction detached home is $335,000, a three bedroom of 1,646 square feet in Fairview, observed September 18, 2026. With every Tennessee program applied a beginning teacher reaches about $146,000; stretched to the FHA limit of 31 percent of pay, about $157,000.

4.1 What the saving is worth instead

Target is $20,100, the cash to close on a $335,000 home at three percent down plus about three percent in closing costs. Assumes the household saves five percent of gross pay today, and the same five percent plus the annual rent saving in an Upward community. The upper bars are optimistic for the lower-paid roles, because a household spending more than half its income on rent is unlikely to save five percent of it. Saving the cash to close does not by itself make the purchase possible: the income limits in the chart above still bind. For most of these households the saving shows up as financial slack, not a closing date.
