you'll likely get a higher price and sell it within a day or two via agent. I'd choose one with high volume. Per my experience with The Timeshare Store, for a 50 point contract, you can even try a bit higher than "going rate" and might get a bite, as those small contracts are in short supply. I listed 50 point VWL at $95 when going rate was in the $90-92 range for small contracts. Got an offer the 1st day at $90. Said I'd wait a few days, offer raised to $93 later that day--sold. Contract was not fully stripped, but no current points.
The 10% fee was worth it for the fast, easy sale. I think the commission might be 8.5% now?? With a high volume agent, you should expect it sold in les than 1 week, assuming it's a WDW DVC. Plus, they deal with ROFR. All you do is sign the papers.
