What this means
- Valuation. Prices are 33% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are up 2.9% over the past year (U.S.: +1.2%).
- Supply. Listings are 67% below the 2017-19 norm and rising (+10% vs. a year ago): still a tight market.
- Negotiating. Buyer leverage is low (5/100; U.S.: 54): homes typically sell at or above asking (103.6% of list); 13% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 31% of the median household income (U.S.: 35%); it takes about $174k a year to keep the payment at 30% of gross pay. That includes about $1,357 a year for home insurance (U.S.: $1,790).
- Disaster risk. FEMA expects about $87 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. Leaning up: likely −4% to +12% over the next 12 months (79% chance of a rise).
