What this means
- Valuation. Prices are 44% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are up 4.1% over the past year (U.S.: +1.2%).
- Supply. Listings are 39% below the 2017-19 norm and falling (−14% vs. a year ago): still a tight market.
- Negotiating. Buyer leverage is moderate (58/100; U.S.: 54): homes sell for about 8.8% below their final list price; 12% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 25% of the median household income (U.S.: 35%); it takes about $49k a year to keep the payment at 30% of gross pay. That includes about $1,699 a year for home insurance (U.S.: $1,790).
- Disaster risk. FEMA expects about $101 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. Leaning up: likely −6% to +11% over the next 12 months (74% chance of a rise).
