DVCRM has their guarantee that if the points delivered to your account after closing don't match what was promised in the listing/contract then they will make you whole.
We saw this recently with someone, I can't remember who, that had a seller use points for a cruise after they went to ROFR. So this Broker says they will compensate you if that happens. But in my case they said they'd remove that guarantee if I didn't use their preferred title company, the slow moving and overpriced Magic Vacation Title. I had not seen this caveat disclosed before I asked to change due to the delay.
