When looking there please be careful. Use only people with a lot of posts and read to see what they have posted. Try to get a judge of character. As much as possible on the internet. Get a contract, it is best for you and the person you rent from. It protects both of you!
Definitely read the sticky threads at the top of the rent/trade board. That should answer a lot of questions and there is a section in the FAQ thread called "a word to the wise" you should definitely read.
We are owners and have successfully rented out points we couldn't use so we've had good experiences from the "sellers" perspective. Good luck with renting points and hope you enjoy your stay at DVC. Several renters of ours have gone on to buy after they used our points.
We were looking at doing th same but to many wanted full payment up front and we decided to invest it in our own ownership.
Best of luck. Follow the website if you do which is covered under the DVC section.
