I don't feel that the partners are doing anything malicious to destroy the 3rd partners equity.

One situation like this can destroy his lending reputation, and rightly so.Also, if 15,000 is all it takes to tap him out, then he is very small time.

Some marinas charge high daily parking fees or have no parking.In places like Florida, boats are destroyed by bad weather, which seems to happen a few times per year. 

My first thought is, if she agrees to leave the place, and doesn't destroy it, take that option. 

Big players such as Bill Gates are buying massive amounts of land and destroying millions of trees, turning regular farms into GMO farms.

Since the majority of repairs are for tenant damage, it's hard to predict how much that will cost because there is no way to guess what they are likely to destroy--- and they can be very creative about destruction.So I do not get over-extended, I keep my credit in excellent shape in case I ever want to borrow, and I screen like crazy before I let a tenant in.For commercial real estate, there is a reason that is a game for the big boys.

The tenant isn't going to pay you $10k if they have a stove fire and set the place ablaze destroying the kitchen.

Great info, I didn't even think of it in the perspective of what can destroy the property in the case of the tenant living there.

those could be/are big assumptions, equivalent to "what if an asteroid destroys the planet?"
