What this means
- Valuation. Prices are 82% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are up 2.4% over the past year (U.S.: +1.2%).
- Supply. Listings are 67% below the 2017-19 norm: still a tight market.
- Negotiating. Buyer leverage is moderate (40/100; U.S.: 54): homes sell for about 1.1% below their final list price; 25% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 41% of the median household income (U.S.: 35%); it takes about $145k a year to keep the payment at 30% of gross pay. That includes about $1,261 a year for home insurance (U.S.: $1,790).
- Disaster risk. FEMA expects about $161 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. Leaning up: likely −6% to +10% over the next 12 months (72% chance of a rise).
