What this means
- Valuation. Prices are roughly in line with local incomes (+8% vs. this area's pre-2020 price-to-income norm).
- Prices. Home values are up 4.6% over the past year (U.S.: +1.2%).
- Supply. There are 19% more homes for sale than the 2017-19 norm and falling (−24% vs. a year ago), so buyers have more to choose from than before the pandemic.
- Negotiating. Buyer leverage is low (16/100; U.S.: 54): homes typically sell at or above asking (105.9% of list); 17% of listings had a price cut (U.S.: 26%).
- Affordability. A mortgage on the typical home takes 75% of the median household income (U.S.: 35%); it takes about $385k a year to keep the payment at 30% of gross pay. That includes about $1,861 a year for home insurance (U.S.: $1,790).
- Buy vs. rent. Buying costs about $5,703/mo more than renting a typical home (mortgage payment vs. typical rent).
- Disaster risk. FEMA expects about $340 a year in natural-disaster damage per $100k of building value (U.S.: $155), mostly from earthquakes. Earthquakes aren't covered by standard homeowners insurance.
- Outlook. Leaning up: likely −4% to +13% over the next 12 months (81% chance of a rise).
