We’ve had a couple threads about inventory lately, but from early Dec. till around late Feb. inventory can be very erratic so I don’t think you should read too much into it.
If I go to http://www.sdlookup.com/Market-92106-Point_Loma and look at Inventory History I see that inventory dropped through the fall, bottoming around Jan 1 and is now starting to come back. This is the typical seasonal pattern. Expect houses that didn’t sell last year to come back on the market in the coming months as spring season returns.
