What this means
- Valuation. Prices are 21% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are up 10.1% over the past year (U.S.: +1.2%).
- Supply. Listings are 77% below the 2017-19 norm: still a tight market.
- Negotiating. Buyer leverage is low (14/100; U.S.: 54): homes sell for about 6.5% below their final list price; 0% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 27% of the median household income (U.S.: 35%); it takes about $54k a year to keep the payment at 30% of gross pay. That includes about $1,244 a year for home insurance (U.S.: $1,790).
- Disaster risk. FEMA expects about $142 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. No clear direction: likely −7% to +10% over the next 12 months (66% chance of a rise).
Next 12 months
No clear direction
A rise is somewhat more likely than a fall, but not by enough to call. Likely change: −6.8% to +9.5% (80% range; middle estimate +2.5%), chance of a rise 66%, of a 5%+ drop 14%.
