Is there a way to separate from them legally without getting a lawyer involved? 

One that involved firing their entire field operations team, which I thought was key to their success.

10% is probably a little steep, and like John said, a flat fee may be more reasonable.Setting up a proper STR is not cheap, but once you are set up properly, you deal with routine breakage.I recommend managing yourself and saving the 20% personally, getting a rockstar cleaning team and a reliable handy person, using something like Hospitable that can help automate messaging when listing, and reading the book from the bookstore here called Short-Term Rental, Long-Term Wealth.

Should have done more digging up front on everyone involved in the deal, not just the managing GP.

We keep everyone in the loop all throughout the process.To stay on track, we maintain a comprehensive checklist that covers all the tasks involved in closing a deal.

If the tenant doesn't cure the issue w/in the timeframe then the PM should cure the issue I.e send someone over to clean the yard, and tow the vehicle if necessary.

-------------------------------------------I am involved in a construction project which requires a Builder’s Risk policy/coverage…something off the beaten track for most people.

Both are on autopay, have insurance, keep their places clean, and are civil to each other.The upstairs tenant is a school teacher in her late 40's. 

I'm no exactly new to BP but have never introduced myself or gotten involved. 

There is a ton of trust involved on both sides, but especially when you're the one shelling out the money.
