A mortgage agreement in principle gives you an idea of how much you may be able to borrow and shows estate agents and sellers that you are serious about moving forward.

In many cases, this can be arranged quickly. Our mortgage advisors in Bristol are able to secure an agreement in principle within 24 hours of your initial mortgage appointment, helping you move forward without unnecessary delays.

Getting an agreement in principle does not commit you to a mortgage, though it can put you in a stronger position when you are ready to make an offer. We tend to see many first time buyers in Bristol look to secure one early so they can search for properties with a clearer budget in mind.

How Long Does An Agreement In Principle Last?

An agreement in principle usually lasts between 30 and 90 days.

The exact length will depend on the lender, though most give enough time to search for a property and make an offer. If it expires, you can normally apply for a new agreement in principle without much difficulty.

It is worth checking the expiry date early, especially if you are actively viewing properties.

Does an Agreement in Principle Guarantee You Will Get a Mortgage?

No, an agreement in principle does not guarantee you will be accepted for a mortgage.

It is based on the information you provide and an initial credit check. When you submit a full mortgage application, lenders will carry out more detailed checks, including verifying your income and assessing the property.

If anything changes or new information comes to light, the outcome may differ from the original agreement in principle.

Does an Agreement in Principle Affect Your Credit Score?

An agreement in principle can affect your credit score, though this depends on the lender.

Some lenders use a soft credit check, which does not leave a mark on your credit file. Others may carry out a full check, which can be visible to other lenders.

Applying for several agreements in principle within a short period can have an impact, so it is usually better to keep applications focused.

How Will The Information You Give For an Agreement in Principle be Used?

The information you provide is used by lenders to assess how much you may be able to borrow.

This includes your income, regular spending, and credit history. Based on this, the lender will decide whether to issue an agreement in principle and give an estimated borrowing amount.

If you move forward with a full mortgage application, the same information will be checked in more detail to confirm everything is accurate.
