I'm sure you'll get plenty of tips. Here's mine (we bought one resale).
#1. Buy where you want to stay the most. It's important, because of the 11 month booking advantage at your home resort vs the 7 month at other
DVC resorts. If you're not sure where you want to stay the most, then ask questions here to see which one fits you and (possibly) your family the best.
#2. Once you've finished with #1 above, you'll find that the number of resales is now a much more manageable number. So the second part is....determine how many points you think you'll need. Use the points calculator here to figure out what it will cost in points to make your "usual" vacation plans. The factors that determine point needs are:
a. Which resort will you be staying at? (see #1 above)
b. How long do you plan to vacation each year? If you are
looking at vacationing every other year, figure out that trip
length and divide by two to get an average annual stay length.
c. What type of accommodation will you need?
- Studio and 1BR sleep 4
- 2BR sleeps 8
- Grand Villa sleeps 12
d. What time of year will you usually travel? Points vary by season.
Now you have a rough idea of how many points you need.
#3. Check the resale listings to see if a contract with close to that many of points is out there. Don't look for a perfect match in the resales...get something "close enough" to your point need....say within 25-50 points.
#4. Check the status of the contracts being offered for resale. Have they used this year's points? Have they borrowed next year's points? Those two are called "stripped" contracts because they restrict the ability to vacation right away. Obviously, they are worth considerably less per point than a full contract will all points available, or even the ones with banked points from a previous year (but watch the expiration date on those).
#5. If you don't see a contract you like, call the various brokers and let them know you're interested. Many contracts never make it to the market because the brokers have developed a "wait list" for contracts of various sizes and locations.
#6. Everything's negotiable, so don't be afraid to offer less than asking, or different terms, or who pays closing, etc. The worst they can say is no.
#7. Be aware that Disney has the right of first refusal (ROFR), so if you negotiate a "steal", Disney will buy it out from under you as they have the contractual right to do.
There really weren't that many other considerations for us. We didn't care much about use year, but that can be important if you always vacation at the same time of the year. We're all over the calendar, so use year wasn't very important to us.
Good luck!
