Can I convert a commercial complex to a multi?

[Ryan Dossey]

I have a question. My wife and I are looking to house hack. Could I buy a unit with more than 4 units and merge some together to qualify for a standard mortgage? For instance I find a home that has 5 units. I want a large master suite so I knock out walls and make a larger unit. What would have to be done to accomplish this? I imagine that I would need to most liekly use a HML or private funding and refi out with a conventional correct? Anyway to buy a 5 or 6 unit and convert down?

Same situation if I find an 8plex of efficiency units could I knock out walls and turn into a nicer 4plex?
