Although Discover doesn't offer a conventional mortgage refinance, consumers can refinance their primary mortgage with one of Discover's home equity loans to change their rate or term or to take out cash. The company offers fixed-rate home equity loans, which may be used to tap into a home’s equity as a second lien mortgage or refinance a primary mortgage. Consumers can borrow anywhere from $35,000 to $300,000, which should suit most borrowers, though those hoping to refinance more expensive homes will have to look elsewhere.

Discover does not require the applicant to pay any fees at closing. There may be fees in servicing such as late fees, early loan payoff costs (reimbursement of some closing costs), etc., depending upon the borrower’s subsequent actions. Discover accepts credit scores of 680 and above. They look at your full credit profile, including debt-to-income ratio, how much equity you have in your home, your income, and your credit score, among other things. To determine exactly what terms Discover can offer you on your home refinance, consumers should contact the bank directly, apply online or visit their website. The company offers loan calculators on its site that can be used to get an approximate idea of what they may qualify for.

Discover's large customer base means some complaints are to be expected. Discover doesn't have an unusual amount of complaints compared to many of its competitors and it still maintains an A+ rating with the Better Business Bureau due to its prompt handling of complaints. Hopefully you won't have to deal with your mortgage lender too much once you've completed your refinance, but if you're concerned about customer service, you can try calling Discover to assess their customer service yourself before signing up or explore a few other options.
