Hi Sue --
Question -- why are you doing a condo conversion, instead of a townhome split with a party wall agreement? Does the zoning not permit lot splitting?
The lending industry holds condos in lower regard than attached single family townhomes, even if the real estate market is indifferent to the distinction. A half duplex with land ownership and a party wall agreement is superior to a 2 unit condominium association, because there is no need for an HOA or an association to own the land.
If legally permitted, dividing the land and writing a party wall agreement is they way I'd go. Of course, there are other issues -- like water taps. In Denver, the Water Board likes to see an individual tap for each townhome unit; but I have seen conversions with a single tap addressed in the party wall agreement -- sort of a utilities only HOA.
As for the report -- I'd try to go with the old 2055. If the lender is okay with a duplex on the old 2055, they should be okay with the condo or half duplex townhome on the same report. Are they really willing to accept a single report for both situations? It will take a lot of narrative, but I guess it can be done.
I would argue the better choice would be two reports that are similar in content, but one for the duplex and one for the half duplex. In fact, the most conservative approach would be a 2-4 unit income property report for the duplex, and a 1004 ASF or a 1073 Condo report for the half duplex. But since the lender doesn't want that, the old 2055 is probably the best option.
