There are thousands of mortgage brokers out there so finding one isn’t that difficult. However, finding a good one may be slightly trickier so it's vital you do your research before committing. Ideally, you want a broker who is able to give you as big a choice as possible so they can compare mortgages from different lenders to find the right one for you. To determine whether you have found a good mortgage broker or not, consider the following things.
1) Will they find you the deal that suits your personal circumstances?
2) Will they find you a flexible lender?
3) Will they do the majority of chasing on your behalf?
4) Are they tied to an estate agent or lender?
