@Jack Lindstromdefinitely house hack. and if you're trying to 'cash flow' a house hack - reframe your thinking. 

I'm closing on a 3 unit house and I'm looking for a Property Manager.

Look for books on "how to repair your house". 

From my experience, the reps at section 8 truly want to find suitable housing for their voucher holders hence I would be very suprised if they lowered the rent beyond the current rate.

I don't see doing really well with RV parking spots but there are a couple of folks renting RVs near our lake house and they seem to do OK.

They said they would sell me to directly if I wanted the house.

Adding additional assets, a familiar market, buying a house "for free" as I call it, and gaining experience with lower level of risk How did you find this deal and how did you negotiate it?

I am not sure what the ARV would be, specially because the other houses in that street currently have a lower value than what this house is listed for.

They said they would sell me to directly if I wanted the house.

That POP moved north into Shelby Park and then north again into Smoketown where houses that were recently 100K now sell for $200K+ and that story isn't done yet.
