I wouldn't take the fact that Dave Ramsey endorses Timeshare Exit Team that they offer a legitimate service. They just happen to pay him a lot of money for the endorsement.
I don't think of them as a legitimate service at all. When TBN allowed a commercial for the same exit company, I emailed TBN and didn't see the commercial after that. I told them these companies take money and don't promise anything.
What they do, and I know you agree, is they make timeshares seem like the worst thing you could possibly buy, and so that keeps the cost down.
The first SBP weeks 9-43, 47 I bought, I paid $1,300 for an annual week. I was excited to get it for that price. Now they cannot be given away. I have taken a lot of free weeks. I was hoping they would gain some value so that I could sell them later on for a bit of a profit. That was 12 years ago that I started acquiring weeks. They are now a negative value.
