Orange County's annual tax foreclosure sale is scheduled to take place today.

The Orange County Office of Real Property, which runs the sale, says there are 107 properties for sale, including 20 homes.

Officials say that the properties may go for as little as 50 percent of their market value.

Buyers are urged, however, to not get caught up in the moment and know what they are buying. There may be liens, fees and needed repairs to make the homes and properties livable and clear of other outstanding debts.
