Resale purchases (as of this year) are no longer counted toward the total # of points needed to attain "VIP" levels of ownership. VIPs receive certain benefits, like unlimited housekeeping check-ins (without a fee), unlimited free reservations per year and a slightly earlier reservation window for certain types of reservations. The lowest VIP level requires 300,000 points, rather like 2 weeks worth in a 2BR during prime season and it goes up from there.
The savings on resale is usually substantial enough to not worry about this, and most resale owners are satisfied with paying a rare extra fee, if they make many short reservations in a year and use up the freebies. For most points usage purposes (reservations at FF resorts, exchanges via II/RCI and cruises), there's
no difference between developer buyers and resale buyers.
Also, if the resale contract purchased was
originally sold to its first owner
prior to Oct 2001, then the points are not eligible for use in "PlusPartners," the way of using points for hotels, car rentals, airfare, theme park tix and nightly stays at selected non-FF timeshares (in the RCI Points network). This may be upgraded to eligibility with an additional developer purchase, though, so it's not impossible to attain through resales. FWIW, FF has been handling more resale sales than in the past as well.
If one plans to stay at their home resort during prime time most years, it may make sense to buy there for the early booking window (especially at the most popular beach destinations). It may make sense to make a developer purchase as an add-on, if VIP privileges are negotiated into the deal. There are a few times when people just prefer or need to deal with the developer. But as I stated earlier, resale is usually the way to go, saving 70% of the purchase price!
