Check Balboa Ridge activity and click on all the units. Do comparisons on location, square footage and price. Then check recent sales. Check to see if anyone posted any NODs or foreclosures on them. Short sales may end up selling for less, potentially and most likely bringing down the comps.
Eventually the developer may end up reducing. I personally think 315k is too high and wouldn’t do it. There are units in UTC selling for less and better hood.
