When I checked for short sales in the active listings in San Diego County only, detached and attached, I got 933.
I input ‘%short sale’ in each of the remarks, conf remarks, and supplemental categories. Some guys put ‘not a short sale’ just to be picked up on these types of searches, so it’s probably +/- 10% or so.
If you don’t put the % in front, you only get the ones that have ‘short sale’ as the first two words.
