Buy a home after foreclosure, short sale, deed-in-lieu-of or bankruptcy expert
Helping families/people that have lost their homes get back into another in as little as 6 months
Appliance 'attached' to the property are considered as 'part of' the property. Such as light fixtures, built in appliances, etc. Refrigerators, washers, dryers, etc. are considered personal property so you can take those.
If it were me in the situation, would I take the appliances? Probably. I would def. try to leave at least the outside in as decent shape as possible for the neighbor's sake. So that they don't have an abandoned looking property that lends itself to possible theft and just affects the overall appeal of the neighborhood.
Once again, this is just a matter of deciding how much your appliances, etc. are worth to you and as far as legalities go, I am not aware of any issues with taking your appliances with you when you vacate.
Best of Luck.
