3 Person Mortgage

James Best explains how a three-person mortgage works.

Can you have a three-person mortgage? Can three people be on the same mortgage?

Yes, you can have a three-person mortgage. If that suits your situation, it’s good news – there may be a solution out there for you.

I would add, though, that not all lenders will accommodate this. You will need someone helping you that knows which lenders will or won’t allow three people on a mortgage – but a fair few lenders will look at this scenario.

Can you get a mortgage with friends in this case?

Yes, you can. There’s no rule that says you need to be related to the other people on the mortgage. It’s absolutely relevant and correct that three friends can be responsible for the mortgage and all live in the same house.

How do mortgages with three or more applicants work?

It’s important to understand the reason why you would want three people on a mortgage. It could be that all three of you are going to live in the same property and all three incomes are needed to support the mortgage.

One of the checks mortgage lenders do is that the mortgage will be affordable for all occupiers of the property. Essentially, if you have three lots of income to use rather than a joint mortgage with two, it probably means you could borrow more.

If three friends were to purchase a property together and all live in it, it’s likely that they could borrow a bit more from a mortgage company. Essentially, the mortgage is supported by three lots of income and three people are sharing the same household expenses.

It would mean three people are responsible for maintaining the mortgage and all three sign the property deeds. You all own the property, shared with the other two.

What deposit do you need? How much can you borrow with three people on a mortgage?

So there isn’t a specific amount of deposit that you need. Some lenders would allow a 5% deposit for three joint buyers, subject to criteria and affordability assessment.

But whenever we restrict the mortgage lenders in some way, it can also restrict other aspects of your case, such as deposit. It may be that when you’re looking at your options for three people on a mortgage, you may need more deposit. You might need to increase it from 5% to 10%, for example.

There is no specific requirement – it’s all subject to the lenders available and the terms they can offer you at the time you apply.

What documents do you need with three people on the same mortgage?

Documentation-wise, there wouldn’t be anything extra compared to a joint mortgage with two people. The same information would just be needed for all three people.

Speak To an Expert

Come on in and be quite forward with what you’re after – just be very honest with your mortgage broker. It’s good to make sure that we know absolutely everything about you. That way we can’t be blindsided by a lender. An open book policy is very good when coming to see your mortgage broker. 

Does it cost to add someone to a mortgage?

It can. Perhaps you’ve got a joint mortgage with two people and you’re looking to add a new party. The lender may charge a fee to administer those changes to the current mortgage. There could also be a cost on the legal side of things, as a solicitor would need to add the person onto the mortgage contract and the property deeds.

Do you pay stamp duty when adding someone to a mortgage? What other costs are involved?

Other costs would be those we’ve mentioned – fees to the mortgage company and the solicitor for the legal transactions.

With regards to the stamp duty, that really depends on your tax position. You could incur stamp duty if you’re being added to a property, even though you’re not physically purchasing it in the usual way.

In this specific instance it’s advisable to speak to a qualified professional for tax advice. They will confirm whether or not stamp duty is payable.

What are the pros and cons of having three people on a mortgage?

The pros include that your mortgage is likely to be larger than a two-person mortgage. That’s because three sets of income will be considered. Also, because those household bills are shared between three people rather than two, your costs are lower – so you could get a higher mortgage and afford a more expensive home.

The disadvantage, though, is that the three buyers would be financially linked to each other. Any negative things that happen – such as a missed mortgage payment or credit card payment, or falling into arrears – would not only affect your own credit score, but often the other two parties’ too.

You have to be acutely aware of who you are getting a mortgage with. You’re all indirectly responsible for each other’s credit score, because you are linked together.

Also, if three friends buy together, it’s reasonable to think that at some point one of them might want to exit that mortgage. They might meet somebody else and want to buy a home with them instead.

That could be difficult if we’re relying on all three incomes for that mortgage, and it could put strain on the other two parties if they can’t support the mortgage themselves – or don’t want to. So it’s important to be aware of that and jointly think about what could happen in the future.

Which lenders offer mortgages to groups of three or more people? Are there many?

I won’t name them, but having done some lender research today in December 2025, of those we use, between 25% to 30% can consider a mortgage for three or more people.

How do you get a multi-applicant mortgage? How can a mortgage broker help here?

As of today in December 2025, with 25% to 30% of lenders offering these mortgages, a broker can help because we know which ones they are.

That can save you time and make the process more streamlined and relevant to what you’re looking to do. Without that, you would have to research it all yourself, and hopefully choose a lender that not only offers three-person mortgages, but also presents the most suitable terms.

Then you’re in a position to make an informed choice about whether a three-person mortgage is right for you.

Key Takeaways:

  • Having three sets of income considered generally allows the group to borrow a larger mortgage amount and potentially afford a more expensive home, as household bills are shared across three people.
  • Not all mortgage lenders will accommodate a three-person mortgage, but a fair percentage (25% to 30% as of December 2025) of lenders do consider this scenario.
  • All three applicants are financially linked, meaning a negative event like a missed mortgage payment or falling into arrears by one person can negatively affect the credit scores of all three parties.
  • A significant disadvantage is the difficulty that may arise if one of the three buyers wishes to exit the mortgage, as the remaining two may not be able to support the mortgage on their own.
  • A mortgage broker is highly recommended; they know which lenders offer multi-applicant mortgages, saving the applicants time and helping them secure the most suitable terms.

YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP WITH YOUR MORTGAGE REPAYMENTS.
