You can complete an appraisal on any form you wish as long as it conforms to USPAP. You may want to wander over to the FNMA website and read the info on the 2055 form because DTU will not order a 2055 for a multi-family property. The 2055/2065's are for single family's.
But as long as your client knows they can't sell the loan to FNMA on a 2055-maybe it's a home equity loan???, and you tell them about it, then have at it, but only if you can produce a credible report/value using the 2055 that conforms to USPAP.
I have had lenders request a duplex appraisal be done on a 1004 and considered the unit as a whole combining GLA, beds, baths etc. I asked these lenders if they would prefer the duplex form and they addamently asked for the 1004. The 2055 should be able to be done in the same way.
I hope you did fully explain the REAL situation in the report and that your report was based on a 'Hypothetical Condition' per instructions of the LO. Without, that's a report that will hang over your head for a very long time.
I pretty much came up with what you said Ben, to make it compliant with USPAP. I will check out the site you mentioned. I already sent my concerns to the lender making sure they know what they are ordered, and how its highly unusual. No income approach on an income property
If you are not comfortable doing a drive by on an income property refuse to do it. Today I got an order for a drive by on a 2055 form. The property turned out to be a 55 acre farm in a conservation area. I told the mortgage company that the format was inappropriate. The mortgage co. called me back and said that I should use comparables from thirty miles away. I told those idiots that my fee would be $1,000 and that I could do the report during the second week in December. The mortgage co. called me back and said that they would get another appraiser, I have no doubt that some fool will give them what they want.
