Once again, we've done it to ourselves. The lender/investor community has begun asking for the listing of the subject property because, although the form asks for "any current listing," appraisers seldom provide it. When the lender/investor requires a copy of the listing, it is discovered (for example) that the appraised value of $119,000 is on a house that is currently listed for $74,000.
Or the investor asks for a copy of a listing that the appraiser swears doesn't exist, that the house is not currently listed, although the realtor's for sale sign is clearly visible in the photo (usually next the the appraiser's car). The listing is for $60,000 and the appraisal is for $80,000.
Or the appraiser says the zoning is SFR, the highest and best use is SFR, there are no significant adverse influences near the subject. The subject is 6 bedrooms, 4 baths and about 1,000 sq. ft. larger than any of the comparable sales. The major arterial location is obvious from the location map. The lender requests the listing, and lo and behold, it's zoned commercial and the current and anticipated use is as an adult group home.
One last one, a "SFR" on an acre and a half, parking lots from adjacent commercial businesses are visible in the photos. All the comps are located in subdivisions (curvy streets, cul de sacs) and on 8,000 +/- sq. ft. lots. Subject is on a major arterial. A call to the local zoning authority reveals the subject is zoned commercial. A copy of the listing reveals the "average in every way SFR" to be a teardown for commercial development.
I say, give them the listing. You have nothing to hide and it adds valuable information to your report. If you don't want to give the listing itself, give a 12 month listing history, with prices and dates.
