Planning your deposit and repayments
Pay off credit cards or save for a mortgage deposit?
Both use the same pot of money. Before moving your savings, compare what each choice leaves for your deposit, buying costs and monthly budget.
This guide helps you prepare a comparison. The right choice depends on your finances and the mortgage options available to you.

Can you get a mortgage without clearing credit card debt?
A mortgage may be possible with an outstanding card balance. Clearing every card is not a universal requirement. Before deciding how to use savings, ask for a comparison of the deposit, remaining commitments and mortgage required under each realistic option.
For how lenders assess balances, payment history and planned repayment, see our mortgage with credit card debt service page (opens in a new tab). This guide focuses on allocating your money before buying.
Work out which savings are actually available
Start with money you can access and use for the proposed purpose. Keep restricted savings, expected gifts and money tied up in a property sale separately until their availability is clear.
Set aside purchase costs
List legal work, surveys, moving costs and any applicable property tax. Costs and tax rules differ across the UK and by transaction. Use estimates for your own purchase, then replace them with quotations.
Home movers should also allow for selling costs and any charges on the existing mortgage. Do not count the same sale proceeds towards both repayment and the new deposit.
Keep an accessible reserve
Allow for unexpected expenses and changes in income. The amount depends on your circumstances; a mortgage application is not a reason to leave yourself unable to cover an urgent bill.
Check savings withdrawal penalties. For a Lifetime ISA, read the official withdrawal rules (opens in a new tab) before using money to repay a card. A withdrawal charge can reduce the amount you receive.
Worked example: three ways to allocate the same savings
Suppose a buyer has £35,000 in accessible savings, a £5,000 card balance and a proposed £250,000 purchase. They set aside £5,000 for buying costs and a reserve combined, leaving £30,000 to divide between card repayment and the deposit.
These are illustrative figures, not a mortgage quotation or a recommendation. They exclude future interest, new spending and changes in costs. The £5,000 allowance is an example, not an estimate of what your purchase will cost.
| Allocation | Keep deposit | Part repayment | Clear card |
|---|---|---|---|
| Card repayment | £0 | £2,500 | £5,000 |
| Card balance left | £5,000 | £2,500 | £0 |
| Deposit left | £30,000 | £27,500 | £25,000 |
| Deposit as share of price | 12% | 11% | 10% |
| Mortgage required | £220,000 | £222,500 | £225,000 |
Clearing the card increases the mortgage needed by £5,000 in this example. It also removes that card balance, subject to any residual interest or further transactions. These effects must be assessed together; the table cannot tell you which option a lender will accept.
The purchase price less the deposit gives the mortgage required here. Your own calculation should separately show any fees you intend to add to the loan, where permitted, and their effect on borrowing and cost.
Compare monthly affordability and total cost separately
What happens to the card costs?
Record the interest rate, balance, required payment and what you can afford to pay above it. For a promotional deal, add the expiry date and the rate that follows. Do not assume another transfer offer will be available.
Where borrowing costs more than savings earn, repayment can save interest. Access to emergency funds and withdrawal or repayment charges also matter. MoneyHelper explains the savings-versus-debt comparison (opens in a new tab).
What happens to the mortgage costs?
Ask the adviser to compare available options at each deposit level using the same mortgage term and repayment basis. Include product fees, monthly payments and the period being compared. A different deposit does not automatically produce a different interest rate.
The lender’s affordability calculation may differ from your household budget. Ask what card commitment it will use and whether intended repayment changes that assessment.
Agree the repayment timing before applying
- Before committing to a property: compare realistic purchase prices and cash allocations with the adviser.
- Before the mortgage application: confirm which debts remain, which will be repaid and the source of repayment funds. Declare the debts requested, including those you plan to clear.
- Before the lender’s deadline: supply the required evidence and meet any repayment condition. Keep your adviser informed if the plan changes.
- Before completion: check the final funds needed and avoid assuming that money already used for repayment is still available for the purchase.
Bring a one-page decision record to your discussion
- Money available: accessible savings, restricted funds and the source of any contribution.
- Money reserved: itemised purchase costs and a separate emergency allowance.
- Two or three allocations: repayment amount, balance left, deposit and mortgage required.
- Monthly position: take-home income, essential spending, card payments and proposed housing costs.
- Dates and uncertainties: promotional expiry, expected funds, sale timing and evidence still needed.
Ask the adviser to record the assumptions used, which options were assessed and what would trigger another review. If your income varies, include quieter months rather than relying only on the best month.
Questions about choosing between debt repayment and a deposit
Is partial repayment worth comparing?
Yes. Paying some of a balance may reduce interest and leave more cash for the purchase than clearing it in full. Ask the adviser to assess the remaining debt and deposit together. Neither a smaller balance nor a particular deposit percentage confirms that the mortgage will be available.
Can I use my Lifetime ISA to clear the cards?
Check the withdrawal rules before moving money. A withdrawal to repay cards will generally be subject to a charge unless a permitted exception applies. A qualifying first-home purchase follows a separate process through your conveyancer. Do not treat the displayed account balance as unrestricted cash.
What if my family offers to pay the card balance?
Explain who is providing the money, whether repayment is expected and any conditions attached. Keep evidence of the transfer and its source. Ask which checks the lender requires; calling money a gift does not make it one if you have agreed to repay it.
Should I delay buying until the debt is cleared?
Compare the likely repayment timetable with your housing costs and ability to save. Waiting may improve your position, but purchase prices, mortgage products and personal circumstances can change. Set a review point using a realistic budget rather than assuming that a fixed waiting period will produce approval.
How should we compare plans if the property price changes?
Recalculate the deposit percentage, mortgage required and purchase costs for the new price. Keep the card balances and available savings up to date too. A plan assessed for one property price cannot simply be carried across to a more expensive home.
Can I count a future bonus towards repayment?
Show when it is expected, whether it is guaranteed and what evidence is available. Keep a separate plan that works if it is delayed or lower than expected. Do not promise repayment by a mortgage deadline using money whose availability has not been established.
