Totally agree with Dean. The APs are only returning $800 in value. You'll save more than that on another 130+ points by adding them to your resale.
As a follow-up to the timing issue, buying a resale is a lot like buying a house. First you have to find one you like. Then you need to negotiate terms with the seller. Even on a
DVC resale, everything is negotiable. Could take a few minutes, or it could take a few days if you have to go back and forth a few times.
Once you have a written contract, it needs to go to DVC to see if they want to exercise Right of First Refusal. If DVC thinks the terms of the contract are a bit too generous, they will simply buy it at YOUR negotiated terms, and you get to start all over looking for a new contract.
As I said, DVC has up to 30 days to take the contract via ROFR, so that could put the contract on hold for up to 4 weeks.
Assuming you pass ROFR, you then need to close on the contract. After closing, it takes a few days for the paperwork to be filed and DVC to formally recognize you as the owner.
A lot of the timing would depend on how anxious the seller is to move the process along. I've seen reports from frustrated buyers who were left hanging for weeks just waiting on the closing.
If you find a seller that is committed to keeping the process moving along, and if DVC declines ROFR in less than 30 days, you probably could complete the process in 5 or 6 weeks. But those things are totally out of your control.
And, as I said in my first reply, finding a contract could be the most difficult part of the process for you. As I understand it, contract of less than 150 are very popular. Many resale brokers will keep their own private waiting list of folks looking for specific contracts. Those under 150 rarely make it to the web sites before they are already spoken for.
Good luck.
