What this means
- Prices. Home values are down 0.9% over the past year (U.S.: +1.2%).
- Supply. Listings are 64% below the 2017-19 norm and falling (−40% vs. a year ago): still a tight market.
- Negotiating. Buyer leverage is low (35/100; U.S.: 54): homes sell for about 8.9% below their final list price; 0% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 29% of the median household income (U.S.: 35%); it takes about $71k a year to keep the payment at 30% of gross pay. That includes about $1,696 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. No clear direction: likely −8% to +8% over the next 12 months (59% chance of a rise).
