I think it's a great name. As johname said, the plural sold for 10K in the past, and that can only help the cause. I think the pural works much better, but neverless the singular is still nice.
As for value, I feel this name screams end-user. Vacation homes are a big business and I dont see that changing anytime soon.
The extension def hurts the name, but I still feel you will make a nice ROI with the right end-user (depending on what you paid for it of course).
Overall I feel possible high $xxx to low $xxxx+ end-user value.
Good Luck
