Mortgages for Foster Carers

Foster carers can apply for a mortgage like other borrowers, but the way affordability is assessed can be different. The main differences are usually how lenders treat fostering payments and what evidence they ask for.

This guide explains how foster carer income is commonly considered, the documents that may be requested, and the factors that can influence how much you can borrow.

Can you get a mortgage as a foster carer?

In many cases, yes. Lenders will still focus on the fundamentals of mortgage lending, including:

• whether the monthly repayments are affordable based on your household income and outgoings
• whether the mortgage term and loan amount fit within the lender’s lending policy
• whether you can provide the documentation the lender needs to verify income and circumstances

Where foster carer income can make a difference is during underwriting. Some lenders may include it in full, some may apply a cap or only include it under certain conditions, and some may not treat it in the same way as employment income.

How foster carer income is calculated for mortgage affordability

Mortgage providers do not all use the same method. The key variable is often how they treat the type of fostering payment you receive and the evidence you can provide.

Remittance notices vs other income evidence

A common reason foster carer applications succeed (or stall) is the lender’s approach to the income figure used for affordability.

• Remittance notices: some lenders may use these documents to assess fostering payments.
• Other evidence: in some cases, lenders may assess income using net amounts after certain expenses (where applicable).

Because the lender’s method can change the income figure used, two foster carers with similar real-world circumstances may be assessed differently depending on the lender’s criteria.

Income inclusion rules and caps

Even when fostering income is accepted, lenders may:

• include it at 100%
• include it at a capped percentage
• include it only if certain conditions are met (for example, length of time fostering)

This is one reason why lender selection can matter. A lender that caps income may still offer a mortgage, but it may not maximise borrowing capacity.

How lenders work out your borrowing capacity (in plain English)

Many lenders estimate borrowing capacity using an affordability model that often includes an income multiple approach.

The exact multiplier varies by lender and circumstance, so it is not possible to state a single figure that applies to everyone. In practice, lenders may consider income multiples as part of their assessment.

Illustrative example (not a quote)

If a household has:

• £30,000 salary
• £22,000 fostering income

Then the eligible income used could differ depending on whether fostering income is included.

• If fostering income isn’t included: £30,000 × (illustrative multiple) ≈ (illustrative result)
• If fostering income is included: £52,000 × (illustrative multiple) ≈ (illustrative result)

Your actual borrowing will depend on the lender’s affordability assessment, your outgoings, and other factors.

Evidencing foster carer income

For foster carers, the right evidence can be as important as the income itself. Requirements vary by lender, but many will look for documents that confirm both the arrangement and the payments.

Documents lenders commonly request

While every case is different, it’s typical to expect evidence such as:

• remittance notices (where the lender uses these to assess fostering payments)
• confirmation from the local authority or fostering agency that the fostering arrangement is in place
• evidence that fostering is ongoing, and in some cases confirmation of expected duration

How long you’ve been fostering can matter

Some lenders may prefer applicants to have been fostering for a minimum period before they will consider the fostering income for affordability. The timeframe can vary by lender.

If you are early in your fostering journey, it can be helpful to understand lender preferences before you commit to an application.

Deposit and affordability factors

Your deposit and overall affordability picture still play a central role in mortgage decisions.

Deposit considerations

Many mortgage routes require a deposit, and the minimum deposit needed can depend on the mortgage type and lender criteria. In some cases, foster carers may find that deposit expectations are similar to other self-employed or non-standard income scenarios.

Outgoings and household commitments

Lenders will consider your monthly commitments alongside your income. This can include existing loans, credit commitments, childcare costs, and other regular outgoings.

Because fostering income may be assessed differently by different lenders, the same set of outgoings can lead to different affordability outcomes.

Credit history and mortgage outcomes

Bad credit does not automatically prevent a mortgage, but it can affect:

• how many lenders are willing to consider the application
• the level of scrutiny applied to affordability
• the range of mortgage options available

For foster carers, it is especially important that the application aligns with lender policy on both income assessment and credit history.

Government schemes and shared ownership options

If affordability is a challenge, some borrowers may be able to consider government-backed routes or shared ownership options, subject to availability and eligibility rules.

Examples include:

• First Homes
• Shared Ownership
• Right to Buy

These schemes can have different requirements, and the best route depends on your wider circumstances.

How a mortgage broker can help with a foster carer application

A foster carer mortgage application can involve more variables than a straightforward employment-based application—particularly around how income is evidenced and how it is treated for affordability.

A broker can help by:

• identifying lenders whose underwriting is more likely to consider fostering income in a way that supports affordability
• highlighting the evidence needed to match the lender’s income assessment approach
• reducing wasted applications by focusing on lenders that are a better fit for your circumstances

Key points to remember

• Foster carer income can be used for a mortgage, but lender treatment varies.
• The way fostering income is evidenced (for example, remittance notices versus other documentation) can affect the income figure used.
• Affordability is often assessed using income multiples, so inclusion rules and any caps can materially change borrowing capacity.
• Credit history and the length/ongoing nature of fostering arrangements can influence lender decisions.

Understanding how lenders assess foster carer income can help you approach the process with more clarity and reduce the risk of delays caused by mismatched underwriting requirements.
