I'm looking to invest in small multi-families in Pennsylvania, ideally in the $80- 120k purchase price range.If possible !

If these issues are persistent, it could affect your rental income and tenant satisfaction.Long-Term Investment Goals: Reflect on your long-term investment goals.

I just purchased a multi-family rental property.

rent by the room, rent by the unit (small MF), rent out an ADU, etc.If you plan on renting by the room, then maybe more square footage and potential rooms to rent.If it is small multi-family, then you can look at similar size rentals to see what their market rates are or use programs like Rentometer.com or BP rental rate calculator. 

You are going to have "seasoning" issues trying to take cash out.

Zoning should not be too much of an issues, but uses may alter parking requirements. 

There's a ton of information available on these forums if you're ever unsure about anything, take a look around, chances are another person has encountered the same issues and share their experiences on here.

I-if it's "big expense", I get ahead of this issue by whipping out a receipt book (you can buy one at any store like Target, Wal-Mart, Staples, Office Depot, etc) and jot down the work that was performed, materials, hours, amount of people, other expenses, etc.

If I do move, I'm considering a house hack on a multi-family, ideally a 4-plex.Honestly, I'm familiar with downtown Houston, Spring, The Woodlands, etc. but nothing past the Galleria on the West side. 

If so, would this still cause issue with the S-Corp tax rules?
