@Jim K. This is exactly why I have gotten fed up with real estate podcasts, forums, etc. It's all a bunch of sales guys trying to sell you "financial freedom" by spending $2,000 on their seminar. Or how easy it is to make a million dollars in 90 days starting from scratch. It's ludicrous.
When I bought my second rental property I was called by my agent about a week before closing and said he had an odd request from the seller. The seller (an older, recently widowed man) asked to stay in the house for 3 days after closing since he needed the money to pay for his next home.
My first thought was, absolutely not! I knew that would make it easy on him to leave any trash or belongings he didn't want behind for me to handle. My agent said that he would help (which he never did), my brother (who was a partner at the time) said what harm can this old man do? We were getting an pretty good deal on the house so I thought, Ok I'll help this gentleman out hoping he would do right by me for being decent.
Fast forward to the day I get the house. I open the door to trash left everywhere, food left out, furniture that was left behind, a garage completely full of old junk. I knew I shouldn't have done this and I was kicking myself.
But that's not even the worst part. I came back a few days later to start the renovation on the house and started emptying the house, my brother was there to help. After about 30 minutes I hear a loud yell from my brother with a handful of cuss words, so I run to where he was at. On my way there I was meet with a pissed off black cat hissing at me! The old man left a black cat trapped inside the house that my brother let loose when he opened a cabinet door! Since it was in a small town there is no such thing as animal control so I had to figure out what to do. Anytime we would get near the cat he would hiss and try to attack us. This cat had all of its claws and was able to climb up door frames and walls, it was wild!
It took us a few days before we could get it out of the house as it refused to leave but we were finally able to get it to leave the house on it's own. While all of this was going down we also found a litter of kittens hidden in a box in his overgrown back yard that we had to figure out what to do with as well.
Needless to say, don't be an idiot like me and let a seller stay in the home after you close or you may get attacked by a pissed off cat!
