Duplex listed as commercial

[Myles Young]

Found a duplex that works with the numbers in a quiet neighborhood. Looking at the taxes and property information has shown that the property is listed as commercial which is confusing to me since it’s in a residential area no where near commercial buildings. 

My lender that I had set up has informed me that they will not be able to lend on this property due to the listed commercial. Are there any reasons for concern with a property listed commercial as a duplex? Are there any benefits to listed commercial?
