What this means
- Valuation. Prices are 33% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are down 1.9% over the past year (U.S.: +1.2%).
- Supply. Listings are 4% below the 2017-19 norm and rising (+10% vs. a year ago), close to pre-pandemic levels.
- Negotiating. Buyer leverage is moderate (58/100; U.S.: 54): homes sell for about 1.7% below their final list price; 33% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 30% of the median household income (U.S.: 35%); it takes about $103k a year to keep the payment at 30% of gross pay. That includes about $1,915 a year for home insurance (U.S.: $1,790).
- Buy vs. rent. Buying costs about $799/mo more than renting a typical home (mortgage payment vs. typical rent).
- Disaster risk. FEMA expects about $95 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. No clear direction: likely −7% to +9% over the next 12 months (64% chance of a rise).
Next 12 months
