Purchasing building that was previously split into condo parcels

[Brad Bass]

I'm currently under contract for a 5 unit building and have hit a bit of a snag.  One of the previous owners split the units into their own parcels, which classifies them as "condominiums".  However, I am purchasing the building in its entirety and there is no existing condo association.  The units have never actually been sold individually and the previous deed has all 5 units listed on it and there are no individual unit deeds associated with any of the units.  

Since these are "condos", the bank is saying that we will need to order 5 appraisals, 5 inspections, have to pay higher interest rates, etc.  Despite the parcels being split up, it is virtually no different than a standard 5 unit complex.  I still have to insure it as a 5 unit building in its entirety, it will be one deed and title transfer, etc.  

Are there any grounds for justifying/convincing the bank to treat this as a 5 unit apartment building as is the case for all intensive purposes?
