It has two units, but the house is only a legal one family, looking to possibly purchase it and live in one of the units and rent out the other, one as a Airbnb or just as a regular rental would need to get some kind of financing to make this purchase by being only a legal one family a conventional mortgage I think would be out of the question.

It has been rented out as a complete unit for 3 years now. 

Investment Info:Large multi-family (5+ units) other investment.
