Joint Mortgages for Couples, Friends & Families
Buying a home with someone else can increase the income available for a mortgage assessment, but it also links the applicants financially. Start with the property, deposit, applicants and intended ownership structure so the case can be reviewed properly.
Standard joint mortgages, buying with a partner or friend, family-supported applications and joint borrower sole proprietor structures can all work differently. Lender criteria and affordability assessment apply.
What is a joint mortgage?
A joint mortgage is a mortgage taken out by two or more borrowers. A lender assesses the applicants together, which can mean more income is available when affordability is calculated.
The important point is that the mortgage is a shared legal commitment. A named joint borrower can normally be responsible for the whole mortgage debt if another borrower cannot or does not make their contribution. It is not simply a case of each person being responsible for their own percentage.
Different people can buy together for different reasons.
The right structure depends less on the relationship label and more on affordability, ownership intentions, contributions and what each person needs from the arrangement.
Buying with a partner
Couples may combine incomes and deposit funds when buying a home together. Both applicants' income, commitments and credit profiles can be relevant to the lender's assessment.
Buying with a friend or sibling
Friends, siblings or other relatives can apply together. It is particularly important to agree how deposits, ongoing payments and ownership shares will be treated before completing.
Family helping someone buy
A parent or family member may be able to support affordability by joining the borrowing. Depending on the lender and circumstances, a joint borrower sole proprietor structure may also be relevant.
Applicants with different circumstances
Different incomes, employment types, financial commitments or credit histories can affect the lender options available. The complete applicant profile needs to be considered rather than looking at one income figure in isolation.
How lenders assess a joint mortgage
Combining incomes can increase borrowing capacity compared with an application based on one income alone, but it does not automatically produce a larger mortgage or a lower interest rate.
A lender will consider the applicants and property as a complete case. That can include:
- Income and how each applicant earns it
- Regular expenditure and existing financial commitments
- Credit history across the applicants
- Deposit size and source of funds
- Property value, type and intended use
- Mortgage term and applicant circumstances
- The lender's own affordability and underwriting rules
Standard joint mortgage or JBSP?
These arrangements solve different problems. The key distinction is whether everyone named as a borrower will also own the property.
Borrowing and ownership usually sit together.
In a typical joint home purchase, two or more people apply for the mortgage and the buyers are also registered as owners of the property.
- More than one borrower is named on the mortgage
- The applicants are assessed together
- Each borrower can be liable for the mortgage debt
- The legal ownership arrangement still needs to be selected separately
More than one borrower, but one property owner.
With a joint borrower sole proprietor mortgage, often shortened to JBSP, another person can join the mortgage without becoming a legal owner of the property.
- More than one borrower can support the affordability assessment
- Only the sole proprietor is registered as the property owner
- The supporting borrower remains responsible for the mortgage
- Availability and criteria vary between lenders
Joint tenants and tenants in common are ownership structures.
They are not separate mortgage products. In England and Wales, people buying a property together commonly need to decide how their ownership will be recorded.
A joint case is only as simple as the complete borrower profile.
One applicant's circumstances can materially change the lender options even where the other applicant has strong income or credit.
One applicant has adverse credit
Lenders can review the credit history of everyone applying. The type, age and severity of previous credit issues may affect eligibility and product choice.
Different income types
One applicant may be employed while another is self-employed, a company director or has variable income. Evidence requirements and the way income is assessed can differ.
Unequal deposit contributions
Contributing different amounts does not remove the need to think carefully about the mortgage liability and intended ownership. Discuss legal ownership separately with the conveyancer.
Family support
If somebody is helping affordability but does not intend to own the property, it may be worth establishing whether an appropriate lender offers a JBSP or another suitable family-supported structure.
What happens if circumstances change?
A joint mortgage can last for years. Consider what the arrangement means if income, relationships or ownership plans change later.
One person stops contributing
The lender can still look to the other named borrower or borrowers for the mortgage payment. An informal agreement to split payments does not normally divide the lender's contractual rights in the same way.
You separate
Separation does not automatically remove either person from a joint mortgage. Until the lender agrees to a change, the existing borrowers can remain responsible for the debt.
One person wants the mortgage alone
A transfer into one name is normally subject to lender approval. The remaining borrower may need to demonstrate that the mortgage is affordable without the other applicant.
A JBSP supporter wants to leave
Removing a supporting borrower later is not automatic. The lender will normally need to be satisfied that the remaining borrower can meet its affordability and underwriting criteria.
Start with the case, then narrow the lender route.
A well-prepared joint mortgage enquiry makes it easier to identify the relevant questions before an application is submitted.
Share the purchase and applicant details
Provide the property, price or value, deposit, mortgage amount, applicant circumstances and intended timeline.
Clarify the borrowing structure
Confirm who intends to borrow, who intends to own the property and whether a standard joint application or a structure such as JBSP needs to be considered.
Prepare the supporting information
Income evidence, bank statements, identification, deposit information and property details can then be prepared around the requirements of the proposed lender route.
Application, valuation and legal work
The lender carries out its underwriting and affordability assessment. Valuation and conveyancing then form part of the wider mortgage and purchase process.
Bring the information that explains the whole case.
You do not need to know the exact mortgage product before making contact. Start with the facts that affect affordability, structure and lender criteria.
- Property address or the area you intend to buy in
- Purchase price or estimated property value
- Deposit available and where it is coming from
- Required mortgage amount
- Income details for each proposed borrower
- Existing loans, credit and regular commitments
- Whether each borrower will also own the property
- Any credit issues or unusual income circumstances
- Your expected completion date or purchase timeline
Questions to understand before applying together
The lender's exact criteria will vary, but these are some of the structural questions worth resolving early.
Can I get a joint mortgage with a friend or sibling?
Potentially, yes. Joint mortgages are not limited to married couples. Friends, siblings and other relatives can buy together, subject to the lender's applicant, affordability and property criteria. Consider the ownership arrangement and what happens if one person later wants to sell or leave the mortgage.
Does a joint mortgage mean we each own 50% of the property?
Not necessarily. Mortgage liability and property ownership are separate issues. In England and Wales, joint owners may hold a property as joint tenants or tenants in common. Tenants in common can have unequal beneficial shares. Your conveyancer should explain the ownership structure appropriate to your circumstances.
What is a joint borrower sole proprietor mortgage?
A joint borrower sole proprietor mortgage, or JBSP, has more than one person named as a borrower but only one person registered as the property owner. The supporting borrower can still be responsible for the mortgage even though they do not own the property.
Will applying jointly automatically get us a lower mortgage rate?
No. A joint application can make more income available for the affordability assessment, but the rate available can depend on loan-to-value, credit profile, property, product eligibility and lender criteria. Being a joint applicant does not itself guarantee a cheaper rate.
What if one joint applicant has bad credit?
The lender can consider the credit history of each applicant. A credit issue affecting one person may reduce the number of available lender or product options. The impact depends on the nature, value, age and wider circumstances of the credit history.
Can one person contribute a larger deposit?
Buyers can contribute different amounts, but the mortgage commitment and property ownership need to be considered separately. If unequal contributions are intended to result in different ownership interests, discuss this with the conveyancer before completion.
Can one person be removed from a joint mortgage later?
It may be possible, but it is not automatic. The lender normally needs to agree to the change and will generally assess whether the remaining borrower can afford the mortgage under its criteria. Legal work may also be required if property ownership is changing.
What happens if one borrower stops paying?
Joint borrowers can each be responsible for the whole mortgage debt. If one person does not make their expected contribution, the lender can still require the other borrower or borrowers to maintain the mortgage payments. Missed payments can also affect the borrowers' credit records.
Can more than two people apply for a joint mortgage?
Some lenders permit more than two applicants, but maximum applicant numbers and the number of incomes used for affordability can vary. The intended borrower and ownership structure should therefore be checked against the relevant lender criteria.
What documents are usually needed for a joint mortgage?
Requirements vary, but commonly requested information can include identification and address evidence, income documents, bank statements, details of existing commitments, deposit or source-of-funds evidence and information about the property being purchased. Each applicant may need to provide their own supporting documents.
