Rancho’s Half-Off Sale…It’s been more than a year since home prices dipped below half their former values in Marina, Seaside and Salinas, but—in line with realtor predictions—higher-end properties have been slower to sag.

The sale will be held at 4 pm at the Preserve Hacienda. For info, contact Albert Burney Auction Co. at 800-434-1654. [KA]
