Different approach than slip
I think slip is right that you could find a timeshare for free with one years dues paid for. We did that about seven years ago when we got a week in fort lauderdale fixed week 52 on ebay.
They covered maintence fees for that year, paid closing costs, and fees. The trading power with rci was high cause it was a fixed week 52 (36 points via rci for the 1 bed/2 bath unit) with maintenance fees of $585/year.
I wouldnt recommend this approach unless you have research how to get rid of the timeshare if you dont want it anymore. Often times, you CAN'T. You may be left with either paying the fees and taking the loss each and every year, defaulting (which not only damages your credit, but opens you to legal liabilities).
Have a clear and realistic exit strategy before you buy in case you need/want to sell.
I dont personally believe that many (if any) timeshares have any real value as their MF>average rental income, but if you are dead set on buying one, i recommend buying one with perceived value.
But if you buy a timeshare that has perceived value via ebay, you can at least unload it if it becomes necessary. Not saying you should spend Tens of thousands, but buy something that you are confident can be unloaded in the future. Here is one i found on ebay. Definitely agree with other posters though, take your time and get what you want.
Be picky, it is a buyers market.
