I'm reviewing an appraisal of a new construction property located in a neighborhood of much older housing (50-100 years old.) The sales price range in this neighborhood is from about $50-$170K. The subject came in at $230K! The appraiser went to new construction subdivisions for comps and failed to adjust for the differing neighborhoods and lack of conformity of the subject with its neighborhood. Anyway, I'm trying to find better comps but there's a lack of good data. I can find a few newer houses in this older neighborhood that were built on tear down sites (sites worth about $20K), but they are much smaller houses. Most of these rebuilds have about 1,000 sf versus the subject's 2,100 sf. I'd like to stay away from new subdivisions entirely. The subject's neighborhood is a gang area and there's graffiti in some places. I'd rather stay in the same neighborhood and adjust the comps upwards. I certainly wouldn't have any comps to bracket the upper end- the new construction subdivisions are just in an entirely different class of neighborhood and conformity. Sooo, it looks like all I can do is use comps that sold for less and adjust upwards, probably in excess of FNMA guidelines. I really don't have the option of bracketing the upper end and that's what concerns me. Right now, I'm looking at older sales (3-4 years ago) of a few new properties in the neighborhood and trying to extract an adjustment as to how much %-wise they differed from other areas. Any ideas as to what other lousy data might be useful?
