It was my house prior to marriage and we decided to rent it out.We’ve had two other tenants and never any problems, but this one has been a different story.

was "How solid is your marriage?"

This agreement will contemplate spell out solutions and procedures for for all of your questions above including how to split monies and profits.The biggest thing to remember is a true partnership is like a marriage.

What about if a state decides to outlaw gay marriage (that moved from a state issue to a federal issue -- are you okay with that?)

Generally after marriage any personal property held by either spouse is property the other spouse has an interest in, so yes, a spouse can make claims to property acquired during the marriage such as with a divorce.

Not saying it is predatory, but taken on the whole, the security provided and other claims, it can cause trouble.Private investors or operators/borrowers, small entities with key persons, need to look to the issues of death, incapacitation, incarceration, marriage, divorce, bankruptcy, other judgments and in some cases, aspects of asset management and asset (note) valuation as such may effect medical and death benefits.

I suffer with awful credit and an eviction due to a horrific marriage. 

As far as I can tell every HOA document has something like this one form or another:The term "single family residential purposes" also shall be defined as: (1) one or more persons related by blood, marriage or adoption, which may include only parents and their dependent children, siblings, parents or grandparents; or (2) by no more than two unrelated persons living together as a single housekeeping unit and their dependent children, siblings, parents or grandparents.See Article III Section 3.1 here as an example: https://1drv.ms/b/s!

(no relation via marriage or blood).

Interesting stat about the marriage and wealth thing.
