We had our walk-through today, and we close tomorrow (yay!!), but while we were doing the walk through, we noticed that the sellers left a bunch of crap. I mean junk. There were things like: their fishing net curtains (yeah, seriously), a box of lice treatment for your hair, hangers, nasty towels, broken ladders and tools, and so much more. I am blown away by the amount of stuff they left.
On the flip side, they TOOK some things they weren't supposed to. They were supposed to leave their curtain rods, which was in the contract, and they took them. Also, they called our realtor and asked her if we wanted their front loading washer and dryers. We said yeah, sure! They said they'd leave them for us, and they didn't. That's not in the contract, so there's nothing we can do about that.
Anyway, I'm just frustrated by all of the junk. It's kind of nasty, and it really dampened my excitement about the walk-through.

Re: Walk through= seller's left crap.
That stinks. We had a similar problem, only the opposite side. Our movers left some stuff behind. So annoying. I hope it doesn't take much to get it all thrown out.
As for the washer and dryer, we took ours with us, but they were not listed as an inclusion in the contract and were never part of the deal. The home we bought also took their w/d with them.
I'm sorry for the mess and headache, don't let it get you down.
Let your Realtor know. Most likely you'll have to just throw out the junk and bill them for it (if necessary).
Re: the things they took that they were supposed to leave, I'd also mention it but its going to be far more trouble than its worth to get back the curtain rods (unless they were custom, then it might be worth it). The WD - nothing you can really do about that. Sorry
Most of all...don't let it get you down. You are getting a great new home and this wont even be a blib in your memories
Congrats on the new house!
