The pros of using a mortgage broker are convenience and access to a wider range of lenders. The cons are that you may be charged a higher interest rate and you may not get the best deal.
When choosing a mortgage broker, it's important to compare rates and fees, and to read reviews from past clients. It's also important to be clear about what you want from a mortgage broker - do you need someone who can help you find the best deal, or someone who can walk you through the process step by step?
Whatever route you choose, it's always important to shop around and compare rates.
