Some mortgage brokers charge a fee for their services and some don’t. When you take out a loan via a mortgage broker, it does not cost you more in loan repayments. Brokers get paid a commission by the lender for bringing new business to them, but this does not impact your interest rate. Some brokers charge a fee for their service. They must disclose this fee upfront to you so that you know what it will cost if you engage their services.
