Can you get a mortgage with debt?

Yes, most people who get a mortgage have some debt. What matters is how much it costs you each month, how you have managed it, and what is on your credit file. Here is what lenders check, and what helps.

3D glass cards, for getting a mortgage with debt

Quick answer

You can get a mortgage with debt. Lenders take your monthly debt payments off your income before working out what you can afford, and count credit card balances at about 3% a month. If your debt payments are under about 20% of your income and your credit history is clean, most lenders will consider you.

Higher debts or recent missed payments narrow the choice and can mean a bigger deposit, but specialist lenders exist for most situations. If you are struggling, free help is available from MoneyHelper.

What lenders check for a mortgage with debt

Lenders work out what you can afford from your income, minus your commitments and living costs, tested at a higher rate. Every monthly debt payment, from car finance to buy now pay later, reduces what is left, and credit card balances are usually counted at about 3% of the balance a month, however little you actually pay. They also look at your credit file for missed payments, defaults and court judgments. See how much you can borrow.

Your debt to income ratio

Your debt to income ratio is your monthly debt payments as a share of your gross monthly income. Under about 20% is comfortable for most lenders; above that, some lower the amount they lend, and above about 45% most decline. See the debt to income ratio checker.

If your credit history has problems

Defaults, CCJs, missed payments, debt management plans, IVAs and bankruptcy all stay on your credit file for six years. The older they are, and the more you have done since, the more lenders will consider you. Specialist lenders, many of which only work through brokers, cover most situations. See bad credit mortgages and mortgages after an IVA or DMP.

What helps most

If you want a mortgage with debt, clearing credit card balances before you apply can lift what you can borrow quickly. Making every payment on time from now on. Not applying for new credit in the months before a mortgage. Checking your credit file for mistakes and registering to vote. See mortgages with credit card debt.

Moving debts onto a mortgage

Some homeowners move other debts onto their mortgage to lower their monthly payments. It can cut the monthly cost, but usually means paying more in total, and the debts become secured on your home. Think carefully before securing other debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage. See debt consolidation remortgages.

If you are finding it hard to keep up, speak to a free debt adviser first. MoneyHelper (moneyhelper.org.uk) can point you to one.
