I bought (2) via resale.
(1) on fidelity - got a really good price, great communication, passes quickly
(1) on DVC resale market - good price, took about 60 days to pass ROFR as there was some paperwork error and a lot of unclear finger pointing, and I felt like a crazy person because I had to keep following up (day 40, 45, 50, etc. lol)
I would say though the title company is your real most important component here if you know what you’re buying and what you want to pay. They all have different inventory and so you have to watch all of the sites closely.
