Jus to clarify, this is a RTU ownership correct?
Here are my questions to you (and the ones you should probably ask yourself).
1. How long was my original RTU contract?
2. What percentage of my RTU contract is left (take years left over total years)?
3. If the percentage is less than or equal to 75%, this might be a good deal.
4. Even if percentage is slightly more than 75%, it might make sense (many people would jump on getting 75% of their original purchase cost back for a TS, you could then take that cash and perhaps buy a resale ownership for something else for much less and have cash left over). Look at

I am confident that you can probably negotiate those prices a little lower. (You can also look on Ebay and other locations including the reputable agents often listed on site)
5. How many more years do you plan on using it, and, assuming you are going to try and liquidate prior to end of RTU, how much will you expect to get after all fees and comissions?
You don't need to answer, but those are the financial questions in play.
The emotional question is: Do you want to give up your ownership?
