Otherwise, find a GOOD property manager and they'll be worth their weight in gold.

a judge is going to see that. 6th, get a home inspection. hire an inspector with a mold certification. have him do a complete home inspection WITH testing on anything he feels may be mold. then, take that report back into court with you. thats a professional opinion that will hold more weight in court than anything your former tenant can bring to court. plus, if you are serious about selling the house, you just saved your prospective buyer $400 for their home inspection. lastly, counter sue the people for damages to the house. there is no way that the $1000 will cover all the clean up and damages. you would be surprised how quick they drop their suit when they are hit with one themselves. good luck

This chart says a 75 gallon aquarium weighs 850 pounds when it's full:http://freshaquarium.about.com/od/aquariumsandstan...So, I'd argue that the weight alone, could result in extensive and expensive damage to your floors/flooring. 

You need to weight the cost, quality of tenant and long term value it adds.

There is no guarantee that the floor will hold the weight of the bed and if that thing for some reason bursts could cause a fire.Now back to Emmanuella - there are many things you are not saying, once again.

Worst case, once a year you call your borrower and get verification, or have to be proactive and help them find affordable insurance.2) The borrower stops paying.Solution: a) Modify the note, perhaps add time to the note and lessen the payment. 

The sheer magnitude of information stored there actually added half a gram of weight to my PC.Would much prefer the interaction available here on a more recent post.
