The mortgage application process refers to the series of steps and procedures that a borrower must complete in order to obtain a loan for purchasing or refinancing real estate property. This typically involves submitting an application, providing documentation such as proof of income, employment, and identification, undergoing a credit check, and having the property appraised. The lender will then review all the information provided before making a decision on whether to approve the loan or not. If approved, the borrower will be required to sign a mortgage agreement and pay any necessary fees, after which they can proceed with purchasing or refinancing their property.
