We used them for our recent purchase. I kept checking the others and just could not find what I was looking for in our UY. (I did make a few offers that just didn't work out.) I checked their site and found the perfect contract for us. Initial contact with the broker was 9/25. It took a little time to hear back, and then several days until an accepted offer. The real delay came in waiting for the sellers to return the papers, although they were great about banking some points that would have expired before I'd get them! We went to ROFR about 2 weeks later than I thought we would. And though I had warned them that the banked points would require an addendum, they didn't seem too prepared for that. Luckily, ROFR was not delayed by that.
And then, closing. That was the real time delay, and I think we paid a little more going through them for closing costs, but the price was still right. And the delay could just have been our sellers dragging their feet. We did finally get most of the points a couple weeks ago, but there were 2 contracts. I noted to the closing agent that the number of points they had on the deed was off by one (26 instead of 25.) They did not bother to fix it before sending it to Disney, and Disney would not give us the 25 points until it was corrected by the sellers...
So, short story long, we finally got the rest of the points yesterday. Total time - 9/25 to 2/9, for a nicely loaded BWV contract, $59 pp, in March UY. In time for me to book a room at BWV for F&W.
I never felt that we would lose our money, or be scammed, but they also did not feel like DVC experts like the big 3/4. We had the ability to be patient, but I did try to stay on top of it.
