We took a 20-day trip last spring to Idaho, Nevada, California and Utah and certainly couldn't have done that with a vacation home. If we were all worried about depreciation, we certainly would not buy FWs, boats, ATVs, etc. We would just buy a house with no furniture, not buy a lawnmower and probably would not put in hot water heaters or furnaces as they all depreciate as well.
