Summer is the slowest time for DVC according to multiple brokers. Not only are there less sales, but there are less listings too. Because of this, you have both limited supply and demand. The prices will soften some, but not by a large margin. Come the fall, which used to be low season, there will be more contracts and more purchases because the hype of SWL is going to go into full swing. People will want those points for fall 2019 and will need to be able to book 11 months out. The only way to guarantee that is to make sure you close in the fall of 2018. I foresee another increase on ppp in the resale market come this fall for that reason. If you are a planner, and have the funds, I would say to buy now if you are looking to have points ready to book for SWL. It's all just a personal opinion, but there you have it.
