All charities that accept timeshare donations don't actually take title from you. They will only accept trying to sell it for you through
brokers they have relationships with already. If they feel it can't be done in 30 to 60 days, they refuse to spend their time trying and will reject it. However this should be your first try after selling it for $1 on eBay.
If other charities won't accept your timeshare, we are a charity that will, but we do it differently. You select a closing escrow company to do the work and hold your funds until it's done so you're protected. We are only the final recipient when the title is transferred to us. At that time the escrow company sends the title and a $500 service fee they have on hold for you to us as our fee for accepting the timeshare. Why $500? because we make no money on a timeshare we don't resell, rent out or use. Based on IRS regulations, we hold it for 36 months then offer it back to the resort. Because we do it this way we can grant you a $5,000 donation income deduction instead of only what actual cash may have been received through another charity. The resort's incentive is that we ignore all their bills and don't care if they send us to collection. We don't use credit and have no assets except worthless timeshares.
It's fully legal and has been exhaustively discussed in another forum title "Getting rid of your timeshare". As a last resort (excuse the pun) we are what you can use to exit a deeded timeshare before you end up at Timeshare Relief or several of it's affiliates paying $4,000 or more to try to get out.
