Joint mortgages

A joint mortgage allows two or more people to buy a property together - learn how they work and if a joint mortgage is the right option for you.

What is a joint mortgage?

A joint mortgage is a mortgage that two or more people can take out together to buy a property. They will then own the property together and share the responsibility for making the monthly mortgage repayments.

Typically, they are taken out between spouses or partners. However, it is possible to have a joint mortgage with a family member or friend. Most joint mortgages are between two people, but some lenders allow up to four people to take out a mortgage together.

How do joint mortgages work?

They work in the same way as a regular residential mortgage. The application process is broadly the same, but all applicants will need to provide evidence of their income and go through a credit check.

Even if one applicant earns more than the other or provides the majority of the deposit, the responsibility for repaying the loan is shared 50/50.

However, you can set up a joint mortgage and the joint ownership of a property in two ways: Joint tenants and tenants in common.

This option means that each applicant owns an equal share of the property. For example, as joint tenants, each applicant would own 50% of the property if there were two owners or 25% each if there were four owners. It also means that:

  • If one owner of the property dies, their share automatically passes on to the other owner or owners

  • When you sell the property, profits from the sale will be split equally between the owners

  • If you remortgage, you will need to move to another joint mortgage 

Joint tenancy is what most couples, especially married couples, choose when taking out a joint mortgage.

If you choose to borrow on a tenants in common basis, each owner can own a different share of the property. This is usually based on how much each has contributed to the deposit or pays towards the monthly repayments.

In this case, if one of the tenants dies, their share of the property will form part of their estate. If they want their share to pass to the other owners, they will need to make this clear in their will. 

You can choose how much each tenant owns yourself. For example, if one tenant provided all of a £50,000 deposit on a house that cost £250,000, you could reflect this contribution by agreeing to a 60:40 split in their favour.

How much can I borrow with a joint mortgage?

You can usually borrow more with a joint mortgage because you can combine your incomes. 

Most lenders allow you to borrow around 4 or 4.5 times your joint income, so if both applicants earn £30,000 a year, they could potentially borrow between £240,000 and £270,000.

The exact amount you’ll be able to borrow will depend on your affordability and things like:

  • All applicant’s credit records

  • Your outgoings and debt

  • The size of the deposit you’re contributing to your purchase

What is a joint borrower sole proprietor mortgage?

A joint borrower sole proprietor mortgage (JBSP) is a mortgage that you enter into with another person, usually a parent or close family member. Only you will own the property, but they will share the responsibility for the mortgage repayments.

This is typically used by parents who want to help their children buy their first home without taking full ownership of the property. If you are unable to make the mortgage payments, the other mortgage holders will be liable to cover them.

The mortgage holders who do not own the property will not appear on the title deeds and, therefore, have no legal claim to the property or any increase in its value.

Once the initial mortgage deal ends, you can switch to a mortgage in your sole name if you can afford to do so. 

JBSP mortgages are similar to guarantor mortgages, where a family member agrees to cover the mortgage payments if you cannot. In this case, they provide their property or another asset as security against the mortgage.

Is it a good idea to get a joint mortgage?

If you’re married or in a long-term relationship, getting a joint mortgage will seem like the logical thing to do. It will allow you to borrow more and ultimately buy a more expensive home.

However, there are downsides to having a joint mortgage that you should be aware of. Here are some of the pros and cons of joint mortgages.

Pros and cons of joint mortgages

Joint mortgage pros

Borrow more

Boost your borrowing power, enabling you to buy a more expensive property

Larger deposit

Combining your savings means you can put down a larger deposit to access better mortgage rates

Shared liability

Sharing the liability of the repayments can reduce the risk of falling behind and going into arrears

Joint mortgage cons

Credit score

If one applicant has a poor credit score, it can mean your application is rejected and damage the other applicant’s score

Shared liability

Sharing liability also means that if the other applicants stop contributing to the repayments, you will be liable to cover them on your own

Hard to split

They can be complicated to separate if one of the owners wants to sell their share of the property

Joint mortgages FAQs

Traditionally, a joint mortgage is for two people; however, most mortgage lenders will allow more. Getting a mortgage for three or four people is possible, but this is the maximum most lenders will allow.

Each person who is part of a joint mortgage will have a legal claim to the ownership of the property. 

If you have a joint tenancy, each buyer will have an equal share of the property, so this would be 50/50 if two people are on the mortgage. 

If you have taken the mortgage out on a tenants in common basis, the ownership may not be equal, depending on how you have agreed to split the property. For example, one tenant may own 25%, and the other owns 75% of the property.

One person can cover all the payments on a joint mortgage if they can afford to. Mortgage lenders don’t mind where the money comes from, provided the monthly repayments are made on time.

When you apply for a joint mortgage, both parties will need to provide affordability evidence. However, they will look at the combined income, so each applicant doesn’t need to be able to cover the payments individually.

If one of the holders wants to leave the mortgage, for example, if a relationship breaks down, it is possible to get out of it. 

One option is to buy the other person out so the property can be transferred into just one name. However, this is likely to be expensive, and they will also need to be able to pay monthly payments on their own.

Alternatively, you could agree to sell the property and split the proceeds of the sale between you. It may also be possible to keep the property but rent it out, sharing any rental income between you.

If you decide to rent the property out, check this with your lender first. Most residential mortgages do not allow you to rent the property out, and you may need to remortgage to a buy-to-let product first. 

Any new borrowing you apply for and take out will be recorded on your credit report. If you keep up with the repayments, having a joint mortgage can have a positive impact on your credit score.

Taking out a joint mortgage also means entering into a financial relationship with the other applicants. This means your credit report can become linked to them, and their financial actions could affect your rating. 

For this reason, it’s best to only take out a mortgage with somebody you trust and who has a good credit record.

It’s possible to get one with friends. Most lenders don’t stipulate that you need to be in a relationship or related to take a mortgage together, provided both applicants meet the eligibility criteria.

Each applicant will need to provide evidence of their income and successfully pass a credit check. They will also have to meet any other requirements, for example, be below the lender’s maximum age limit, which can be anything from 65 to 90.
