Just did a refi with them that was arranged through a mortgage broker. In the closing, in addition to signing the usual papers, we had to electronically sign a bunch of documents through their website. It was an incredibly slow and cumbersome process. It took half an hour for the title company's notary to be able to log into the site. Then each page refresh took several minutes, turning what should hvave been a one-hour closing into a three-hour closing.
Other than that, I've had no interaction with them either positive or negative. They funded the loan when they said they would, all the documents were in order, so I guess they did their job.
