Prequalification is an initial determination, based on information that you verbally provide and a credit check, on whether you would qualify for a mortgage loan with BMO Harris Bank. Prequalification is not the same as a pre-approval. Prequalification only provides you with an estimate of how much you can borrow to buy a home, but is not a commitment by BMO Harris Bank to lend money to you or by you to borrow money from us. Prequalification may not be available for all loans or customers. Pre-approval may be required in some instances. You must submit additional information, complete a full application and pay the application fee to be considered for a mortgage loan.
