We served the second tenant shortly afterwards and once they saw how the other situation played out, my wife was able to work with them to get them out without going through an entire eviction process.

@Jordan Sachs I can not speak to PA but in MN, yes, I have seen similar scenarios play out. 

Flipping is probably a little more intense, but can still be done with a day job, but again, my average flip versus my average rental: flip has made much better returns.And as for generational wealth and handing down something to your kids... well, I guess I view it as: if I can hand my kids a $10mm trust fund held in public securities, or $10mm real estate portfolio, they are going to be pretty set either way, but a real estate portfolio will continually have costs and work, a brokerage account is a bit more set and forget, with some periodic rebalancing.

For me, 2- 4 plexus are, most of the time, a cash flow play, and therefore, the ARV is less important in the analysis.
