Advice on buying home that was airbnb

Hello all
not sure if this is the right place to post this. but an opportunity fell in my lap. A previous Airbnb home is coming for sale. 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. Any suggestions would be appreciated thank you.
