Yes, you can move house with existing debt, but your mortgage lender will assess those commitments when deciding what you can borrow. The critical checks are your sale equity, existing mortgage redemption costs, debt payments and the affordability of the new mortgage.

Before committing to a purchase, compare your sale equity and existing debts with a mortgage affordability assessment.

Yes, moving home with debt is possible, but affordability is the real test

Having credit-card balances, a personal loan or another unsecured debt does not automatically prevent you from moving home. The mortgage lender has to assess the proposed borrowing alongside your income, regular spending and existing credit commitments, and the result may change how much you can borrow or which deals you can access.

The key distinction is between moving property and getting a new mortgage. Your sale may be viable even when a new lender will lend less than the mortgage you hoped to take. That gap needs to be identified before you commit to a non-refundable purchase expense or exchange a contract.

How debt changes mortgage affordability

A lender can count existing monthly debt payments as committed spending. A credit card balance may also be assessed using a minimum-payment assumption even when you normally clear the card every month. Personal loans with a remaining term can reduce the disposable income available for the new mortgage calculation.

Your credit report also matters, but debt itself is not the same as having adverse credit. A borrower with substantial balances that are always paid on time is in a different position from someone with missed payments, defaults or recent arrears.

The numbers that need to match

expected sale price minus the current mortgage redemption figure and sale costs
cash available for deposit and purchase costs
balance and monthly payment on each unsecured debt
new mortgage amount required after the move
stress-tested affordability at the lender’s assessment rate
any early repayment charge on the existing mortgage

Ask your lender for an up-to-date redemption figure rather than using the balance shown on an older statement. A mortgage can include an early repayment charge, daily interest or an exit administration fee, and those amounts affect how much equity is actually released.

Do not omit debts from a mortgage application

A lender’s affordability assessment depends on accurate information. Trying to make the borrowing look cheaper by leaving out a credit card, loan or other commitment can cause problems later, especially if the lender independently verifies your credit file or bank statements.

Where the debt is repayable from the sale proceeds, tell the lender that clearly and provide evidence. A confirmed repayment is different from saying that you will probably clear it at some point.

A safer order of operations

Get the mortgage position before making an offer that assumes the maximum theoretical borrowing. Then compare the current mortgage’s early-exit cost with the value of porting it, refinancing or waiting until the fixed period ends. Finally, budget for moving costs, tax or fees that apply to the property and a reserve for repairs.

When your existing debt is already hard to manage

If your current repayments are causing missed bills, do not use the house move as a substitute for debt advice. MoneyHelper can point you towards free debt help, and a debt adviser can look at your whole budget before you take on a larger secured loan.

Selling one home and financing another are separate calculations

Start with the realistic sale price, the mortgage redemption figure, estate-agent and legal costs, and any early repayment charge. The resulting net sale proceeds become the deposit available for the next purchase. Then model the new mortgage on the purchase price rather than assuming the old mortgage can simply be carried over. A lender can agree that you can move while offering a different maximum loan because the new property, income or affordability assessment is different.

Current rates also matter to the affordability decision. The Bank of England Bank Rate was 3.75% on 17 September 2026, while Moneyfacts reported a 6.00% average five-year fixed mortgage rate on 5 October 2026. Those market figures are not an offer for an individual borrower, but they illustrate why a moving-house decision should use an up-to-date payment estimate rather than an old fixed-rate assumption.

Deal with debt before you commit to the new purchase

If the move requires clearing a credit card, personal loan or car finance at completion, include that repayment in the cash-flow plan. Clearing a debt can improve the new mortgage affordability calculation, but it also reduces the deposit available. Ask the broker or lender to model both versions before exchange. That gives you a genuine choice instead of discovering after an offer is accepted that the proposed mortgage is smaller than expected.

Illustrative moving-home funding gap

Worked example

Illustrative example using the current 2026 market context: the Bank of England Bank Rate was 3.75% on 17 September 2026, while Moneyfacts reported an average two-year fixed rate of 5.98% on 5 October 2026. Those are market reference points, not an offer for Alex.

Alex expects £90,000 of net equity from selling a home. The new property needs a £260,000 mortgage, but Alex has £420 a month of unsecured debt payments. If a lender’s affordability model allows only £235,000 of mortgage borrowing, the move has a £25,000 funding gap before purchase costs. The issue is therefore affordability rather than the fact that debt exists.

Suppose a home sells for £420,000 with £260,000 needed to redeem the existing mortgage and £12,000 of selling costs. Net proceeds before other debts are £148,000: £420,000 − £260,000 − £12,000 = £148,000. If a £15,000 personal loan is cleared from those proceeds, £133,000 remains for the next purchase deposit and costs.

Can you get a mortgage while in debt?#

Existing debt does not create an automatic ban on borrowing for a home. The lender will assess income, spending and credit commitments, and large monthly repayments can reduce the amount of mortgage the household can support.

Should I pay off debt before moving house?#

Sometimes clearing an expensive or restrictive debt can improve affordability, but using every pound of house-sale equity to repay debt can leave too little deposit or emergency cash. Compare the effect on the mortgage application with the cost of keeping the debt.

Can I port my mortgage if I have debt?#

Porting is not an unconditional right to the old mortgage amount. The lender normally reassesses the new borrowing and affordability, so existing debt can still affect whether you can increase the mortgage for the next property.

Do credit cards affect a mortgage application?#

Yes. Lenders can consider credit-card balances and required payments when assessing affordability. A card being paid on time is positive compared with missed payments, but the balance can still reduce the amount available for a new mortgage.

Will a lender see my personal loans?#

A regulated lender can obtain information about existing credit commitments and may also ask for supporting documents. Do not assume a small personal loan is invisible simply because its monthly payment is modest.

Can I buy another house while keeping the old mortgage?#

It depends on the intended structure, lender rules and affordability. If the old home will be retained rather than sold, the lender needs to assess both the existing borrowing and the costs or income associated with the additional property.

What should I calculate before selling my home?#

Start with expected sale proceeds, subtract the mortgage redemption amount and transaction costs, then add any other cash that will be available for the new deposit. Compare that figure with the amount the next lender is prepared to lend after considering existing debts.
