What this means
- Valuation. Prices are 72% above what local incomes have historically supported (this area's pre-2020 price-to-income ratio).
- Prices. Home values are up 8.9% over the past year (U.S.: +1.2%).
- Supply. There are 30% more homes for sale than the 2017-19 norm and rising (+18% vs. a year ago), so buyers have more to choose from than before the pandemic.
- Negotiating. Buyer leverage is high (100/100; U.S.: 54): homes sell for about 31.1% below their final list price (as of Dec 2017); 21% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 45% of the median household income (U.S.: 35%); it takes about $104k 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).
- Disaster risk. FEMA expects about $176 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from flooding.
- Outlook. Leaning up: likely −7% to +10% over the next 12 months (67% chance of a rise).
