Get a mortgage in principle instantly, and learn how they help you get onto the property ladder. Our MIP is unique: it checks your credit history and eligibility with 18 lenders to accurately calculate how much you can borrow for a home.

What is a mortgage in principle (MIP)?

A Mortgage in Principle (MIP), also known as an Agreement in Principle or Decision in Principle, is a document from a mortgage lender or broker indicating how much they will likely lend to you for a mortgage

Before you begin house hunting, it’s essential to get a Mortgage in Principle because, combined with your deposit, it will set your budget for purchasing your new home.

When deciding how much to offer for a new home, remember to budget for additional costs associated with buying a house. It's crucial to consider these expenses in your financial plan. 

Using your mortgage Decision in Principle as a guide, it's not wise to exhaust your budget entirely when making an offer. Keep in mind that the actual amount a lender may approve could differ from your Decision in Principle during the formal application process once the lender has looked into your finances more closely.

What information do you need for a Mortgage in Principle?

To determine the amount you could borrow, we'll ask for the following details:

  • Your current and most recent addresses 

  • Your employment status

  • Your income

  • Your monthly expenses, including any existing credit commitments 

Don’t worry if you don’t have all this information to hand; you can save your profile and come back to it later. 

When you apply for a Mortgage in Principle, we'll perform a soft credit check to determine how likely different lenders are willing to accept a mortgage application from you and if there’s anything in your credit history that may impact how much you could borrow. 

Once you’ve got a mortgage Agreement in Principle, you can speak to one of our expert mortgage brokers about the next steps and how you can improve your chances of getting a good mortgage deal. 

How to apply for a mortgage in principle

To get your MIP, tell us about your situation and we’ll check how much you could borrow from a range of mortgage lenders.

Who can get a MIP?

To get a MIP with us, all applicants must be:

  • 18 or over

  • living in the UK

  • have the right to live and work in the UK

We need to know a few things about you so we can work out how much lenders would be willing to lend to you.

When applying for a mortgage in principle, we'll ask for your:

  • address history

  • employment status

  • salary

  • credit commitments

It's okay if you do not have all your information to hand. We'll save your profile as you go, so you can come back to it at any point.

You will not have to give as much paperwork or information as a mortgage application when you apply for a MIP with us.

Other lenders may ask you for:

  • payslips

  • 3 years of accounts if you’re self-employed

  • 3 months' worth of utility bills as proof of your current address

  • photo ID, such as a passport or driving license

Once you have the MIP, you can use it to make an offer on a home.

If the seller accepts your offer, you can apply for a mortgage with your chosen lender or broker.

How long does a mortgage in principle last?

When you get a MIP from a lender, you usually have about 3 months before your MIP expires (between 30 and 90 days).

You can reapply if it takes longer than planned to find the home you want to buy or if you find new, more competitive mortgage deals on the market since you arranged the MIP.

If your lender carries out hard credit checks, try not to apply too many times as it could damage your credit score.
