Two Houses on Common Lot

[Eric Jelen]

I'm just starting out and have been searching for residential multi-family properties.  I'm planning on living in one of the units and renting out the others.  I have come across some properties that have two homes on a single lot.  One in particular has to two 4bdr houses that are on a single lot (listing doesn't say how many baths).  My agent explained that I should check with my lender to see if I could even get a loan for this kind of property before we schedule a showing because there won't be many comps.  My lender got back to me and told me that I wouldn't be able to get a loan for this kind of property.  I was curious if anyone had experience with these kinds of properties?  I have a hard time believing they can't figure out how to appraise the property?
