We highly recommend obtaining an agreement in principle before you start viewing properties if you're planning to apply for a mortgage. This is because an agreement in principle is usually required to make an offer on a property, and it can also help you negotiate prices. As a mortgage broker in Nottingham, we can help you to obtain an agreement in principle from a mortgage lender, which demonstrates their willingness to grant you a mortgage based on your financial circumstances. With an agreement in principle in place, you can have a better idea of what properties you can afford and approach the buying process with more confidence.
