What this means
- Prices. Home values are down 4.4% over the past year (U.S.: +1.2%), 18% below their 2022-23 peak.
- Supply. Listings are 15% below the 2017-19 norm and falling (−25% vs. a year ago), still somewhat tight.
- Negotiating. Buyer leverage is high (97/100; U.S.: 54): homes sell for about 11.2% below their final list price; 14% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 42% of the median household income (U.S.: 35%); it takes about $73k a year to keep the payment at 30% of gross pay. That includes about $3,845 a year for home insurance (U.S.: $1,790).
- Disaster risk. FEMA expects about $1236 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding. Flood isn't covered by standard homeowners insurance.
- Outlook. No clear direction: likely −8% to +8% over the next 12 months (56% chance of a rise).
Next 12 months
