And once again, we play the "name game" making it hard to compare today's coaches to those in the past. Thor makes the "Freedom Elite" Class C coaches which look like rental models (no step, low door, huge rear compartment for German's luggage). A 2012 model M28U sold new for $92,697 and retails for about $58,850 according to NADA blue book. So you see, the 50% every 5 years formula is not too far off the mark. But of course, few people pay retail prices for these things, so let's be generous and assume 40% depreciation every five years.
And if your financial circumstances change, well, you can decide not to vacation at all, or just drive to the beach or something cheap. The timeshare locks you in - for life. You can never, ever get out from under it, which is why you should think very, very carefully before signing documents that commit you for life.
The average homeowner moves about every 8-10 years, so if you get into a situation like that, you either have to walk away from a mortgage and screw your credit (and declare bankruptcy) or rent the property out at a negative cash-flow until you pay down the debt or the market recovers. It is a shitty situation to be in, and many of my friends have had to confront this.
Ahh, television - the source of so much misery!
