First-time buyers taking on record levels of mortgage debt to secure homes
First-time buyers are taking on significantly higher levels of mortgage debt as they battle to secure their first homes, with the average mortgage reaching £229,214 in the first quarter of 2026.
The trend towards higher borrowing has been accompanied by a notable shift in lending patterns, with buyers increasingly opting for high loan-to-value mortgages and extending repayment terms well beyond traditional standards.
In December 2025, 44% of first-time buyers chose mortgages with an 85-90% loan-to-value ratio, up from 41% the previous year, according to Barclays mortgage data. This increase reflects buyers putting down smaller deposits to get onto the property ladder, with average deposits dropping by 14% year-on-year.
The share of high loan-to-value lending, defined as mortgages with deposits of 15% or less, has reached its highest level for over a decade, according to Nationwide's house price review for 2026. This marks a substantial shift in the mortgage market's risk profile.
Extended mortgage terms become the norm
To manage these higher debt levels, first-time buyers are now signing up to mortgages that last an average of 31 years, significantly longer than the traditional 25-year standard. This extension of repayment periods allows buyers to reduce monthly payments whilst taking on larger overall debt.
The value of gross mortgage advances increased by 11.1% from the previous quarter to £77.4 billion in the second quarter of 2026, and was 31.7% higher than a year earlier, according to Financial Conduct Authority statistics. This surge in lending activity underscores the intensity of demand in the housing market.
Lenders push boundaries of affordability rules
Several lenders in 2026 are offering mortgages at more than 4.5 times income to first-time buyers who meet specific criteria, with some lenders offering up to 5.5 times salary. This represents a departure from traditional lending ratios, though it remains within regulatory guidelines.
The Bank of England's Financial Policy Committee introduced a loan-to-income flow limit in 2014, recommending that no more than 15% of any lender's new mortgage lending should be at or above 4.5 times income. This safeguard was designed to prevent excessive risk-taking in the mortgage market.
The willingness of buyers to take on higher debt levels comes against a backdrop of falling interest rates. The Bank of England base rate sits at 3.75% as of 2026, the lowest level since spring 2023, following four cuts in 2025. Lower rates have made larger mortgages more affordable on a monthly basis, even as the total debt burden increases.
Millions remain locked out of market
Despite the surge in lending activity, an estimated 3.5 million potential first-time buyers remain outside the property market, according to the Intermediary Mortgage Lenders Association. This substantial pool of aspiring homeowners highlights the ongoing affordability challenges facing those seeking to get onto the housing ladder.
The combination of higher debt levels, extended mortgage terms, and increased loan-to-value ratios represents a significant shift in how first-time buyers are accessing the property market. Whilst lower interest rates have provided some relief, buyers are committing to debt obligations that will extend well into middle age and beyond.
