Quicken Loans is the biggest mortgage lender for a reason. It has a nationwide footprint and makes applying for a mortgage online very easy on the borrower. It offers competitive rates as well, which helps solidify its position as the best overall mortgage lender.

The online lending application is particularly attractive, as it does not involve the same hassles many traditional mortgage lenders require, like lots of physical paper and typing in a list of all of your accounts. With Quicken Loans, much of that happens automatically when you connect your bank accounts. The application process is quick and simple, which is why so many people use it every year.
