Note too that in Wake County, unlike decades past, there is no meaningful "foreclosure discount" (defined as the fact that winning courthouse bid prices were generally (historically) much lower due to the forced sale feature of NC statutes and Deed of Trust Power of Sale clauses) and this is confirmed by a recent Fannie Mae study.
