Prequalifying for a mortgage loan is pretty easy. Yet, It’s practically purposeless.
Having a pre-qualification letter just indicates that you discussed your financial situation with someone at the mortgage lender’s office. It indicates that you did not provide any documentation. And the lender didn’t verify any of the verbal information that you gave them.
It indicates that the lender merely considered the broader guidelines. And concluded that you are likely to be approved for a loan of up to a certain amount. Then the lender issued you a letter stating that they have pre-qualified your loan application.
