Hope everyone enjoying Memorial Day weekend.

My tenant lives in the unit above me and has been there since before I purchased the property (She is also a section 8 recipient).

@Mikhail EgeDoes Alex live in the house he's renting for 4k per month?

Plumbing/electrical etc are just repairs< same as if you were living there.

You are asking for a lotTo get a deal, with location and needs.You need a good place to live for your Mom so she is close to supermarket restaurant may be park.Find the best place for your Mom and yes work on the financing. 

Which area works best for multi-family investing will depend on a few factors:- will you be living in the property as well?

I live in Illinois, if that factors into any decision on what my initial strategy should be. 

Recommend any tips (for STRs), any guidance etc.We live in the Phoenix metro area..Thanks everyone.

I am planning on House Hacking the 3 unit (live in 1 rent out the other 2)  for a year or 2 and then move out a rent my unit out.$200k is a lot of money if you are in a flat market.   

I recommend using a boilerplate lease agreement, then adding attaching an addendum with a list of rules particular to your shared living space.
