Mortgage brokers play an important role in helping individuals and businesses find the best mortgage for their needs. They act as an intermediary between the borrower and the lender, providing advice and expertise on a range of mortgage options. The cost of using a mortgage broker varies depending on the services they offer, the type of mortgage and the amount being borrowed. Generally, the broker will charge a fee of between 1% and 2% of the loan amount. They may also charge an hourly fee, or offer a flat fee for specific services. It is important to check with the broker about their fees before signing any agreement.
