I am trying to think of the supply/demand impacts:
- The mega-renters will probably dump their contracts, flooding the resale market with supply and making values go down.
- The casual renters will probably get better money when renting their points, as they would no longer be competing with the mega-renters.
- The customers booking rentals will probably have to pay more due to Point #2. Maybe some of them will buy into DVC which may partially offset Point #1?
In my simplistic view, wait for resale prices to go down, buy a contract, and start renting out your points "casually".
