Problem financing duplex that is listed as 2 townhomes by county

[Bernadeau C.]

Hello,

I have a duplex under contract at the moment but I just found out the county has it listed as two townhomes on the appraiser website and my lender just told me that he cannot give me one loan for the property because of how it is listed. 

Does anyone know a lender that will allow one loan for this duplex even though it is technically two townhomes that share a common wall. I am buying it from the same seller and our contract has both of the units on there as one transaction. 

Any thoughts?
