Is there some type of community or organization that will give you comfort that you will easily be able to find the help you need, find tenants and/or resolve disputes if they come up. 

I wrote in a dispute and they didnt make me pay.

Q-94-21862, which terminated the regime of absolute community of property between petitioner and respondent, as well as the Resolution [4] dated August 13, 2001 denying the motion for reconsideration.The facts are as follows:Petitioner Elena Buenaventura Muller and respondent Helmut Muller were married in Hamburg, Germany on September 22, 1989.

Hopefully there's no more.2) What are some precautionary steps you take to avoid dispute, ambiguity (he said, she said) or situations like this? 

move in/move out condition report. signed by both you and tenant. it should explain what condition everything is in when lease begins. if something is new, state it. if something is broken, state it. also, take more photos and video than you think is necessary. if tenant disputes a security deposit deduction, you need proof of original condition. my philosophy is "if its not in writing, it didn't happen." if you have no proof of condition upon move in, you cannot charge tenant for it.

you cannot even win on a dispute over a negotiable instrument with that argument let alone a recorded sale agreement.

@Jon Holdman Intent absolutely matters, I'm not disputing that.

1) Eliminate those without sufficient equity.2) Treat surviving spouse deals differently3) ID competing petitions as disputes means opportunities to solve big problem4) Consider sub-niches: incarcerated heirs, charitable beneficiaries, out of USA, etc.5) If you can cross-reference foreclosure and tax sale properties, it doesn't get much better

Here in Dallas's county it is very easy to file an abstract of judgment on someone's property, and it is very easy to get it removed from the deed all they need to do is dispute the judgment the one that holds the judgment will need to spend money to fight it, and it could cost more than the judgment is worth.Joe Gore

In the mean time the current tenant (my relative), has been receiving letters, at the home, from the county stating that the home is going into foreclosure unless the back tax are paid/disputed by March 31, 2014.
