Also worth noting that they subcontract out a lot of the process to what seemed to be the lowest-bidder. So you'll be dealing with a few different people during the process, won't get much handholding during, and at least in my case, they had some mistakes with the closing paperwork (and provided some of the paperwork that's supposed to be provided at least 24 hours prior to closing more like 12 hours prior)... so read over things carefully.
That said, all mistakes were fixed without any issue, the mistakes looked to be true mistakes (i.e., bringing the wrong piece of paper... something detailing the bank-to-bank payoff stuff I think, not trying to change numbers up from what was expected or anything shady), and I haven't had any problems arise following. My old mortgage company received payment correctly and everything seems to be transfered over and running ok now.
Final thought... their closing sub did forget to ask for a survey prior to closing and asked for one a few months post. I had a copy that I emailed to them; don't know what would have happened if I didn't though.
That said, I'd go through it all again. Noone was trying to scam in there, and it *is* a good deal!
TLDR[Too Long; Didn't Read]: Low cost comes at a price, you'll need to stay on top of the process and it may be a bit rough at the edges
