Overall, I had a good experience with Mike and Pat from RateGravity, but this was offset by my experience with the lender (Webster Five) that was recommended through the site. Both Mike and Pat were extremely responsive, provided a lot of useful information throughout the process, and the flexible offer letter tool was great and easy to use, and the rate I received was competitive. As for the lender, while I understand that they are a small bank, they was extremely unresponsive and slow throughout the process, even though I had provided them with all the information in a timely manner, and it resulted in us having to move our contingency date back a full week. Despite this, the RateGravity team leveraged their contacts at the bank to push most of the process along, and I appreciated their help. Overall, while I had a positive experience with the RateGravity folks, I hope they vet the lenders they recommend better in the future.
