Bought and sold through them and really was extremely satisfied. They were always quick to respond to questions and kept in touch the whole way.
As far as time to close and have use of points, it all depends on how fast the sellers and buyers return paperwork (both offer and final docuemnts), how long Disney takes to ROFR--they have 30 days--and how long it takes Disney to get it up and loaded into the system.
I think right now, most people are reporting an average of 2 months. But, there was a huge rush to buy prior to the resale changes--now that those are all passed and either closed or close to closing, IMO, things should improve in the timeline.
Good luck!
