2 house deal

[Lester Appel]

I am looking at a property that has been on the MLS for over 200 days. I like the area and am comfortable with the neighbourhood and its growth potential.

I just spoke with the seller's realtor and found that at least 2 offers fell through because the lenders will not lend on the property apparently because of the lot being a single lot with 2 single family homes. The lot is R2 and the homes are legal (perhaps the second being a mother in law unit) but there is not sufficient land to separate the homes into individual tax lots. 

I am seeking advice on how to proceed. I ran the property thru the rental calculator and am prepared to make an offer but if the previous suitors could not get conventional loans how can I? 

I am happy to hear what alternatives might be. I am just getting started in serious real estate investing so your input is welcome
