4 Person Mortgage

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

For all four applicants, various documents are needed. It depends if we’re using all the incomes or not, but we would certainly need ID for each person – a passport or driving licence.

If we’re using everyone’s income, we’ll need four lots of payslips for the last three months. We also need bank statements for each of you to verify your outgoings and your income, again for the last three months.

If any of you are self-employed, it’s slightly different. That person may need company accounts or tax calculations submitted to HMRC. Typically lenders need the last two years’.

There’s not a huge difference here in what’s required – there are just more documents to get together between the four of you.

Does it cost to add someone to a mortgage?

If it’s a new mortgage, no, there’s no additional cost, unless you’re doing something like a Joint Borrower Sole Proprietor mortgage.

If you’re adding someone to an existing mortgage, there can be a legal fee involved to complete a Transfer of Equity. That enables you to take someone off a mortgage or add someone on. There would also be legal work involved in updating the property deeds.

A bank or building society may charge a fee to make a change to the application, too. It’s not as simple as taking one name off and adding another. Anyone being added needs to meet the lender’s criteria around credit checks and affordability.

You might bring someone on with no income and lots of debts, which would have a detrimental impact on affordability from the lender’s perspective.

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

A solicitor would confirm exactly what stamp duty would be due, if any. Stamp duty is based on your circumstances – and whether you’re taking on the mortgage debt with that person or buying a share of that property from someone who already owns it.

There are a few considerations here, so speak to a solicitor. Whether it’s a share in a property or taking a property over, there will be some legal work involved. That means legal fees, and potentially some fees with the lender as well.

To bring someone on to a mortgage, you might have to go through a remortgage process, which means submitting a new mortgage application. In turn, the lender may need to value the property, which could incur fees. There might also be product fees.

It’s always best to be prepared – having that conversation upfront will allow you to budget for those fees and understand the process.

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

The biggest one is your borrowing power. If you’ve got a lender taking four incomes into account, you can usually get a bigger mortgage. You might be able to afford a property at a higher purchase price than buying individually or with one other person.

It also makes things more affordable on a monthly basis, because you’re splitting the costs four ways. That includes mortgage bills, utilities, food shopping and more.

For a lot of people, it’s a creative way of getting on the property ladder sooner. Most lenders need a minimum of 5% deposit, but if you club together as a four you could get to that deposit sooner to buy a home.

The biggest downside is that your options will be limited. Not every lender is willing to lend to four people and they often cap it at two. That might mean you’re paying slightly higher rates.

It can also be more complex with four people buying property together. If someone loses their job or there’s a falling out, things can go wrong. It’s also a shared responsibility, as your advisor will explain. When buying as a four, every single person on that mortgage is responsible for the entire mortgage payment.

If you do fall out after you’ve moved in or one of you isn’t able to contribute their proportion of the mortgage payment, that affects you all. Any missed payment goes on all of your credit reports.

So, if you enter into a mortgage contract with others, make sure you’re all on the same page and you’ve got a plan if something does go wrong.

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

There aren’t many. We won’t name the lenders, because that landscape is changing all the time, but certain high street banks and building societies offer these mortgages.

They may only consider two or three incomes, but the mortgage can have four applicants. If you walk down the high street you might find it difficult, but a broker will find you a mortgage to suit your plans and goals.

How do I get a four-person mortgage? How can a mortgage broker help?

Getting a multi-applicant mortgage is similar to any other – it just needs a little more coordination and support. All applications go through the same checks on income, credit history and identity.

Once you’ve got all the documents together, the lender assesses everything as a single application. The key difference is how important it is to be fully prepared and get things structured properly from the start.

With four different people, there are four lots of credit scores to meet the lender’s requirements. Every single person on that mortgage needs to fit that lender’s policy, and this is where we come in.

We understand which lenders will accept multiple applicants – and include all four incomes if needed. It’s also about recommending the right lender for your individual circumstances. If three of you have excellent credit scores and one doesn’t, that could hold you back from a high street bank. We may need to look at an adverse credit lender.

We talked about deposit sources and being self-employed – again, there are lots of different moving parts there. Finding the right lender will be key.

A broker will sense-check the affordability and make sure you get a mortgage of a suitable size. It can be risky to get a vague Agreement in Principle online without providing any payslips.

Getting an Agreement in Principle that’s been sense-checked by a broker avoids you wasting your time. You won’t be turned down for mortgages which could be disheartening, especially if you’ve found a property you really like.

We’re there to support you through every stage. If something does go wrong or you hit any barriers, it’s our job to work with you and find a way forward. We’ll support you all the way through to getting the keys to your new home.

Key Takeaways:

• Getting a mortgage with four people is possible and can be a creative way to get on the property ladder, though not all banks offer this option, which can limit your choices.
• The primary benefit is greater borrowing power, since multiple incomes are factored into the application, potentially allowing the group to afford a higher value property.
• A significant risk is that all four applicants are fully responsible for the entire mortgage payment, meaning a missed payment by one person affects the credit score of everyone involved.
• Lender policies vary on affordability assessment; some may accept four applicants but only use two of the incomes to calculate the loan amount, while others will consider all four incomes for maximum borrowing.
• The application process requires all four individuals to meet credit score requirements and provide documentation, including ID, bank statements, and payslips, with self-employed applicants needing two years of company accounts or tax calculations.
