You could rent to whom ever you would like. Going rate on this forum is $8 to $9 for distressed points and $10 to $12 for points in good standing. As far as renting to family, that would be a price that you would have to come up with. Some owners give the points to family, others may get just enough to cover dues owed on those points, and others may get full boat. Regardless, even if you charge $12 a point the renter or family member is getting a great place to stay at a fraction of rack rate.
