To be able to continue through many different stages the real estate markets had endured over four decades is incredible.

You don’t want to endure the delays of a winter sale.

And frankly, knowledge is only one piece of the "puzzle", the main component is rather the personality - endurance threshold, confidence level, risk tolerance, common sense, persistence and resilience.  

Pit bulls were bred by changing mytochondria to get dna that can endure pain, and horriblest ways imaginable.

I have had to endure many headaches with entitled tenants (2 properties with inherited tenants) who feel they are more owners than I.

Gotta love it if you are going to endure this phase.If you want to construct, then skip college and join a good construction company.

I cannot endure month by month agony (losing money) just with the hope of appreciation - I'm too cheap for that.

That being said, the frequency of discrepancies in the short period of time you've owned definitely seems very very high and I would probably lose a lot of confidence in the turnkey operator at that point.I'm casually looking into different turnkey markets but I do have a lot of reservations including the experiences you've had to endure. 

This limits my ability to see if they are employed, any information on prior rental history, criminal history etc.I planned to ask the owner to get them to sign a month to month and tell them that my intention is not to put them out after each month (which it isn't) but in case things go bad I do not want to endure it for a year.

Sounds like a terrible scenario to throw at her but this was the consequences that we would endure.
