Can You Use a Loan for a House Deposit?

Some mortgage lenders may consider an applicant using borrowed funds for a deposit, while others may not accept it or may assess the extra repayment differently. This guide explains what may need disclosing and how a deposit loan can affect a mortgage application.

ImportantAs a mortgage is secured against your home, your home could be repossessed if you do not keep up the mortgage repayments. Think carefully before securing other debts against your home.

Can you use a loan for a house deposit?

Some mortgage lenders may consider an applicant using borrowed funds for a deposit, while others may not accept it or may assess the additional repayments differently. The source of the deposit must be disclosed accurately. A personal loan adds a monthly commitment that can affect mortgage affordability, so a general guide cannot say whether an application will succeed.

This is general information rather than a route to a particular outcome. The wider risks of taking on additional secured borrowing are covered in second mortgage risks.

What deposit sources may mortgage lenders consider?

Deposit sources can include savings and gifts, but lenders may ask for evidence of the source and apply their own policies. A gift and a repayable loan are not the same, and presenting borrowed money as a gift can mislead a lender. Requirements for gifted deposits, business funds or incentives vary by lender and transaction.

How can a deposit loan affect a mortgage application?

A deposit loan can increase regular committed expenditure and may affect affordability and credit information considered by a mortgage lender. The impact depends on the amount, repayment, timing, credit history and the lender's assessment. Multiple formal credit applications can also be visible to lenders, but the exact impact is not fixed.

More on how credit commitments generally interact with a mortgage or secured borrowing assessment is covered in pay credit card before mortgage.

What else needs budgeting when buying a home?

A house purchase can involve costs beyond the deposit, such as legal, survey, removal, insurance and tax costs depending on the transaction and location. Because relevant figures and tax rules change, checking GOV.UK and MoneyHelper directly is more reliable than relying on static figures published in a general guide.

A basic budgeting checklist can include legal fees, survey costs, removal costs, buildings insurance, and any applicable tax, alongside the deposit itself and ongoing mortgage repayments.

Frequently asked questions

Do I have to tell my mortgage lender about a deposit loan?

Yes. Accurate disclosure of a deposit's source is important, since a mortgage lender assesses affordability and the deposit together. Presenting borrowed money without disclosing it, or describing a loan as a gift, can mislead a lender and cause problems for the application. Lender policy on deposit sources varies.

Is a gifted deposit the same as a loan?

No. A gift is not expected to be repaid, while a loan is a repayable commitment that can affect ongoing affordability. Lenders may ask for evidence to confirm which category a deposit falls into, and presenting a loan as a gift can create problems for the accuracy of an application.

Will a personal loan stop me getting a mortgage?

Not necessarily, but a personal loan used for a deposit adds a monthly commitment that can affect how a lender assesses affordability. Whether an application succeeds depends on the lender's own criteria, the applicant's overall financial position and accurate disclosure, so no general guide can give a definitive answer.
