Scaling house hacking

[Andrew Ager]

So I recently bought my first house hack: townhouse rent by room .

My goal is to buy a new one every year with a FHA loan refinancing into a conventional then reusing the FHA loan for the new property taking my roommates with me to each property while turning the previous one into a full time rental .

I can save the down payment each year easily.

I guess my question is what kind of criteria is demanded by mortgage companies to allow me to do this ? And is there anything else I should know before trying to scale up in this way ?
