What this means
- Valuation. Prices are roughly in line with local incomes (+2% vs. this area's pre-2020 price-to-income norm).
- Prices. Home values are up 5.0% over the past year (U.S.: +1.2%).
- Supply. Listings are 62% below the 2017-19 norm: still a tight market.
- Negotiating. Buyer leverage is low (4/100; U.S.: 54): homes typically sell at or above asking (104.1% of list); 13% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 35% of the median household income (U.S.: 35%); it takes about $209k a year to keep the payment at 30% of gross pay. That includes about $2,262 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 −3% to +13% over the next 12 months (83% chance of a rise).
