You should buy from a licensed real estate broker when electing to purchase from a timeshare resale company. If you deal with individual sellers or non-licensed companies you are risking the money that you pay as well as you will have no place to turn if there is a problem later. When you purchase from a non-licensed company that is supposedly working as a for sale by owner company there is no recourse if you have a problem. Additionally, always make sure any money is put into escrow until closing. All reputable timeshare resale companies will offer this option.
