I rent out our points regularly as we don't go as much now that the kids are grown and gone.
I have always had good luck with the Disboards Rent/Trade board. If you don't post enough you have to pay to list your listing.
I have regular renters who use me year after year -- works great for me and them!
Right now renting points on your own via the Disboards -- the going rate for rental price is $15/point -- unless you have a highly sought after reservation or resort/room type.
I use a rental agreement which I feel protects me and the renter both. You can google
DVC Rental Agreement and find one -- if not and your interested private message me and I will send you the one I use.
I have never used David's so I don't have any experience in that.
