What is the difference between a mortgage in principle and a full mortgage offer?

Buying a home is exciting, but it can also feel confusing with all the jargon you come across. Two phrases that often cause a bit of head scratching are Mortgage in Principle and Full Mortgage Offer. They sound similar, but they mean very different things, and it is worth understanding the difference so you know where you stand in the buying process.

What is a Mortgage in Principle?

A Mortgage in Principle, sometimes called an Agreement in Principle or Decision in Principle, is essentially a lender giving you an idea of how much they might be willing to lend you. It is based on some initial checks, usually a credit search and the information you provide about your income and outgoings.

It is not a guarantee, but it is incredibly useful. With a Mortgage in Principle in hand, you can go house hunting with more confidence. Estate agents and sellers will also take you more seriously because you can show that you have already started the process of securing finance.

Think of it as a ticket to get through the first door. It shows you have the potential to buy, but the lender still needs to look much closer before they will commit.

What is a Full Mortgage Offer?

A Full Mortgage Offer comes later, once you have chosen a property and the lender has had a chance to do all their detailed checks. At this stage, the lender will have gone through your payslips, bank statements, credit history and other documents in depth. They will also carry out a valuation of the property you want to buy to make sure it matches the price you are paying.

When everything stacks up, the lender will issue you a Full Mortgage Offer. This is the official confirmation that they are happy to lend you the money, on agreed terms. Once you have this, you are in a strong position to move forward with your solicitor and get to the exchange of contracts.

Why Does the Difference Matter?

The key thing to remember is that a Mortgage in Principle is only a starting point. It is not binding on the lender and it does not guarantee you a mortgage. A Full Mortgage Offer, on the other hand, is the green light that you are waiting for, and it means the money will be available once all the legal work is complete.

Plenty of buyers fall into the trap of thinking that having a Mortgage in Principle means the mortgage is secured, but that is not the case. Understanding the difference can save a lot of stress and disappointment down the line.
