Basically, an okay deal now is better than a great deal in another few years.I live with my family overseas in a relatively unstable part of the world.

He either purposely took advantage or he is unstable in some manner. either way want him out now..

To add additional context,  I would personally be more willing to sign my name onto a $6M mortgage collateralized against a $10M asset in an "A" market that has historically low vacancy rates, no deferred maintenance and is located in a stable market with a rent roll that covers the debt services and operating expenses with reasonable cushion for reserves than sign my name on a $90,000 loan collateralized against a $100K property in a C/D unstable market with high vacancy rates and where capex will disproportionately impact operations.

Apparently an unstable individual can hold your rental business completely hostage by making false accusations. 

The tenant is mentally unstable, didn't pay rent over a year, got evicted, forced out by the Sheriff and kept coming back to the property by breaking locks and lock picking.

Some of the lists you might consider are Absentee Homeowners with Equity, Seniors with 20+ Year Ownership and Financially Unstable.

I would also say that markets like Manhattan are not super representative of most markets in the US - a lot of foreign investment I'd imagine in NYC, Miami etc - I'd guess a lot of these cash purchases are more about exchanging unstable or risky foreign assets/currencies for perceived stability/safety of US top metro residential real estateI think in a lot of other markets where this isn't relevant - I think most are cash offers being "king" as not having appraisal or other contingencies that might sabotage the sale after 30 days or so and make people re-list (sellers will take less to avoid this risk and downside)

I was recently involved in a thread where the OP was almost radical in her dedication to her short-term $savings at the expense of long term gain, and yet was bemoaning having had a mentally unstable tenant turn vicious on her.If you "face the beast" you must expect to be battered mercilessly at some point.

STR's are unstable with a lower likelihood of guaranteed income.

It might help you, just like this post should have helped you.Either way, if you are feeling unstable because of it, please just lay it down and leave it alone.
