- Prices. Home values are up 3.5% over the past year (U.S.: +1.2%).
- Supply. Listings are 4% below the 2017-19 norm and rising (+5% vs. a year ago), close to pre-pandemic levels.
- Negotiating. Buyer leverage is moderate (49/100; U.S.: 54): homes sell for about 0.7% below their final list price; 26% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 57% of the median household income (U.S.: 35%); it takes about $201k 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).
- Buy vs. rent. Buying costs about $1,945/mo more than renting a typical home (mortgage payment vs. typical rent).
- Disaster risk. FEMA expects about $84 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
