James appears to have cited the applicable law.
Yes, folks sometimes strip houses. (And they've been known to pump concrete down shower drains, too. Or punch holes in walls. Or remove all the doorknobs.) Doesn't mean it's right. And you could get into trouble.
With the lighting fixtures, you could do as Roland suggests--replace the (presumably) nice ones you recently installed with other functioning ones. Same with other items that you could replace. But I wouldn't touch the furnace.
Leave the house in reasonable, functioning condition. Then move on with your life.
Hope that helps.

Now, in all honesty you have nothing since you are being evicted from your home. You likely don't have the pot to pee in (unless you take the toilet too but you did not mention that) so what will the bank do? Would putting you in jail get them much, other than the satisfaction?
