Robert and Emerald Oravec were itching to sell their condominium late last year to move closer to a favorite surfing spot, but they were stuck. They owed the bank $194,000 and figured the most they could get was $180,000.

When they put their San Diego home up for sale a few months later, they fielded five offers within two weeks. It sold for $260,000 in May, allowing them to invest profits in a new home that’s more than twice the size on a large lot and 40 minutes closer to the surfing beach.
