Finding your dream home is exciting, but stepping into the property market without knowing your true buying power can lead to wasted time and heartbreak. Before you book your first viewing or negotiate an offer, you need to know exactly where you stand. That foundation starts with a reliable Mortgage in Principle.

What is a Mortgage in Principle?

A Mortgage in Principle (MIP)—sometimes called a Decision in Principle (DIP) or Agreement in Principle (AIP)—is an official written statement from a lender indicating how much they are willing to lend you.

Having a valid MIP does two crucial things: it tells you exactly what your maximum budget is, and it proves to estate agents and sellers that you are a serious, qualified buyer. In a competitive market, a strong MIP is often the difference between having your offer accepted or being overlooked.

The LPR Difference: Mortgages You Can Actually Afford

Many generic online calculators and automated systems generate inflated figures based on basic income multipliers. This creates a false sense of security that often results in a rejected application when the lender digs deeper.

At LPR Mortgages, we protect our clients from that stress. We do not just run automated checks; our expert advisers manually assess your full financial picture upfront. Whether you have complex income streams, self-employed accounts, or specific visa requirements, we meticulously prepare your profile before approaching lenders.

We ensure the number on your Mortgage in Principle reflects reality—so when you find the perfect home, you can make an offer knowing your mortgage is genuinely affordable and ready to be secured.
