Although we weren't "underwater" on our loan, Brett Martin helped us through a HARP refinance that increased our monthly payments by about $80 but cut our term from 22 to 15 years. I'll take paying $80 * 12 * 15 = $14,400 extra over the next 15 years in order to save $2230 * 12 * 7 = $187,320 over the following seven years. If you plan to stay in your home for the duration of the loan, I recommend at least considering paying more points to drop your interest rate -- we paid a couple extra points and dropped the rate to 2.75% and saved a significant amount of $$ per month. I have recommended Quicken Loans to co-workers, and I know of at least one who is now in the process of a refinance as well. The speed and ease and lack of required funds at closing were all reasons why I'd highly recommend Quicken Loans to anyone in the future.
I received a $5 gift card for writing this review, regardless of whether I had a positive or negative experience.
