Things took off in the last 2 years. We first starting thinking about
DVC in fall of 2016, and BLT was around 110/pt resale at that time. Didn't purchase resale until July 2017 and paid 125/pt for a perfect contract. Was originally grumpy about it, but in hindsight it was a good move. New listings are all 140+ right now.
Like others have said
- economy stronger - built up demand from folks that have been putting expensive dis trips on hold, more people can afford to go. (or are willing to spend the money now, I know I put off big ticket items during times of uncertainty)
- rack rates going through the roof. We had an AoA family suite in Feb 2015 for about 350 a night or so. That same room is 550 dollars a night now for Texas spring break week. We rented DVC points in Mar 2016 and that sold us. We realized we could buy into DVC, have a better location, and better accommodations for the same money.
- Direct pricing increases - DVC charging more, so resale sellers can charge more. Buyers don't have a choice but to pay the increased cost if they want the points
- Location premium. - Some of the biggest increases have been properties with superior locations. Boardwalk and Beach Club have probably seen the biggest spike over the last 2 years (especially considering shorter contract end date), because people want to stay in that location. The monorail resorts stay pretty strong. OKW, SSR, AKV have seen more modest increases but have still gone up. I remember a couple years ago paying 100pp for SSR or AKV was unthinkable. Now it's not unusual for a good contract. I just checked on AKV and saw some folks paying 115 a point. That might be the biggest percentage jump in the last 2 years.
I expect DVC demand to stay strong for at least the next 4 years as star wars land and the 50th anniversary come up. After that, who knows.
Unrelated to DVC resale prices though, the recent cost increases of a WDW vacation might start affecting people soon. I know we've already adjusted our plans for our next trip to attempt to control costs a bit. The biggest thing we cut down on was table service meals. Everything though has gone up quite a bit the last few years.
