San Diego County Treasurer-Tax Collector Dan McAllister has scheduled an auction of nearly 300 parcels on March 19 at the San Diego Convention Center.

The property auction is held annually to satisfy the nonpayment of taxes due, including penalties. In this instance, $7.2 million needs to be paid.

There are 107 improved properties and 182 unimproved parcels ready for auction, McAllister said. Owners have until 5 p.m. March 18 to pay their bills or see their properties auctioned off.

In some years, buyers of parcels have gotten some great bargains, McAllister said.

Interested bidders can buy registration packets for $75 at any of the treasurer-tax collector’s offices in downtown San Diego, Chula Vista, Kearny Mesa, El Cajon or San Marcos.
