10 Ants,
I have 210 BCV points available (please E-mail if interested), and I can tell you that when I rent out my points there will be no hidden costs. The cost per point is all you'll pay.
And from what I can tell from these boards, most people rent their points that way. Now, when you pay that cost does seem to be different from person to person.
Some folks require a deposit, then ask for a portion of the total when booking is complete, and then collects the rest a certain number of days out from the reservation date. But again, the cost per point seems to be final.
Anyway, I hope this helped. And like I said, please feel free to E-mail me if you would be interested in renting from me. Good luck.
