What this means
- Valuation. Prices are 56% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are up 6.5% over the past year (U.S.: +1.2%).
- Supply. Listings are 60% below the 2017-19 norm: still a tight market.
- Negotiating. Buyer leverage is low (12/100; U.S.: 54): homes typically sell at or above asking (100.1% of list); 27% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 30% of the median household income (U.S.: 35%); it takes about $85k a year to keep the payment at 30% of gross pay. That includes about $1,388 a year for home insurance (U.S.: $1,790).
- Disaster risk. FEMA expects about $105 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. Leaning up: likely −3% to +14% over the next 12 months (84% chance of a rise).
