A) Our office just got handed an assignment to perform a residential appraisal on a new development quadplex. So far so good. We do plenty of those, and know the market for long-term tenant rentals well in the subject's market area.
B) The problem is, the developer is adamant that the units are going to be rented on a per-day/week/month basis, ala AirBnB, and as a result, any appraisal performed must approach appraising said property based on per-day/week/month rental prices, market cap rates, etc. rather than as long-term rentals.
Your office chief appraiser should know if appraised as B) it no longer qualifies as a residential loan, it was appraised as a small motel, despite calling it air BnB . The developer/borrower wants it both ways - (and likely did it before )- this borrower wants the low rates of a res loan, but the high income rental of a motel type use to max out the value. .
Whether it is a cert Res or a Cert Gen, they have to do a HBU analysis. If the developer is instructing the HBU of appraisal, it is an unacceptable assignment condition. I would pass on this assignment because something is off at your "office" wrt to letting a client dictate how to appraise , - yes if appraised as a commercial type rental basis a cert gen should do it. . I doubt office wants to pay the higher cert gen fee and borrower does not want a higher interest commercial loan.
