They can hang it on you, ruined there credit, losses can be much more than the value of the property.

That last one was hilarious it reminds me of one of mine from last year when I was walking neighborhoods and hanging big yellow notices on doors.

Look for things that you can use later to negotiate/explain your offer.Liabilities:Bad railings, Tree over hanging neighbors home, etc. 

If I decide to hang on to the property do you think this is a smart move?

If SELLER isn't motivated, find lower hanging fruit.

(Loosely hanging from joist.)ØGarage electrical has seven blown fuses and not panel cover.

My question is this:Should I sell the property and use the cash to invest in a different property with better returns, or hang on to it?

Funny thing was they were usually people with a mental hang up of some kind or people that didn't want to be found by any one or paranoid, so I didn't take them to serious and asked you seem to be the neighborhood busy body so do you know of anyone who... of course you need to reword that.

It's a good place to hang for investor know how.

I have found that doing it ourselves often takes much longer and we would have been better off hiring it out than trying to save money (especially hanging, taping and finishing a house-- although an easy to learn project, that takes forever as a solo project and a decent drywall finisher isn't too hard to find).
