by Dima Williams When Betsey Rider and her husband decided to sell their four-bedroom house in Annapolis, Md., to tap the rising demand this May, they found buyers before even listing the abode. The Riders and the homebuyers settled on a price of $825,000. But days later the appraiser came back with a value of roughly $720,000—more than $100,000 less than the contract price. “We could not comprehend why,” says Rider.
