On the other hand, I expect that anti-landlord policies will be firmly entrenched and taken as gospel. 

What has been your experience with purchasing buy and hold properties using SDIRA funds and the legal fees I should expect? 

Have a gentle but firm conversation with the neighbor, let them know what you intend to do with the property, what your expectations are of him and what his expectations can be of you (even if it’s just about parking).Hopefully this two steps will go a long way to resolve any future issues that are similar to this.All the best.

Could you define:- ballpark expectations on return- time horizon, how liquid you need it to be- how passive?

What other issues can I expect when a septic fails or the foundation needs repair?

Expect to have some wall cracking and maybe even a structural issue to deal with.

I was wondering is it beneficial to get a property manager in a house hack when cashflow exceeds my expectations?

@Oren Harel congrats on your hosting experience, 5-star reviews are not easy to come by these days.I have to caution you on your expectation of earning "passive income" by starting a short term rental management company. 

I'm an out of state landlord and I'd like to sell my last property off in Broken Arrow. 

If thats what you expect then stop now and save your money.
