We have two older mobiles on our property and have had more bad than good renters, had to evect a few. Now have 12 x 60 and not sure if we want to rent again, but money sure comes in handy. Just got rid of a guy who owed electric and part of one months rent, found out he was a coke head and having it delivered here, but at least we didn't have to go through eviction process, gave him a three day notice and he found another place and moved. Not sure we will rent again, or fix some things to make it into guest quarters and sewing/quilting room for me.
Income sure helps with medical bills, but first we have to do some fixing up. Daughter who helps us with dogs and things around here lives very cheap in other one ( she is on disability). Be careful, check refrences and be sure you get enough rent and deposits and refrences.
