For many aspiring homeowners, the dream of buying a first property has become increasingly difficult. While headlines often focus on house prices, it is now the cost of borrowing that is proving to be one of the biggest barriers to getting onto the property ladder.
Mortgage rates have edged higher in recent months as financial markets have become less certain about how quickly interest rates will fall. Although the increases have not been dramatic, even small rises in mortgage rates can have a significant impact on monthly repayments over the lifetime of a loan.
The Cost of Borrowing Matters
A higher mortgage rate may only add one or two percentage points to the interest charged, but the effect on household budgets can be substantial.
For example, a buyer borrowing £250,000 over 25 years would pay around £1,320 a month at an interest rate of 4%. If the mortgage rate rises to 5.5%, the monthly repayment increases to approximately £1,535.
That is more than £200 extra every month, or around £2,500 a year, before taking into account council tax, insurance, utility bills and the other costs associated with owning a home.
For many households, that additional expense is enough to prevent them meeting lenders' affordability tests.
Deposits Remain a Major Obstacle
Saving a deposit continues to be one of the biggest challenges for first-time buyers.
Many prospective homeowners are paying high rents while also facing increased food, energy and transport costs. Building up a deposit of 10% or even 15% of a property's value can take many years, particularly for younger workers and families.
Although there are mortgage products requiring smaller deposits, these often come with higher interest rates, making monthly repayments even more expensive.
House Prices Have Not Fallen Enough
While house prices have cooled in some areas of the UK, the declines have generally not been large enough to offset the increase in borrowing costs.
In many parts of southern England, affordability remains particularly stretched because property prices remain high.
Scotland presents a more mixed picture. Areas such as Caithness continue to offer comparatively affordable housing compared with many parts of the UK. However, local wage levels are generally lower and the choice of available properties can be more limited, meaning affordability challenges still exist despite lower average house prices.
Lenders Are Taking a Cautious Approach
Banks and building societies are continuing to assess borrowers carefully before approving mortgages.
Affordability rules introduced after the financial crisis require lenders to consider whether borrowers could still afford their repayments if interest rates were to rise further.
As a result, some buyers who could have borrowed enough to purchase a property a few years ago may now find they qualify for a smaller mortgage.
Will Conditions Improve?
Much depends on inflation and interest rates.
If inflation continues to fall towards the Bank of England's target, mortgage rates may gradually ease over the coming year. That would improve affordability for many first-time buyers.
However, there are still risks. Rising global energy prices, geopolitical tensions in the Middle East and continued uncertainty in international markets could keep inflation higher than expected. If that happens, interest rates may remain elevated for longer, delaying any significant improvement in mortgage affordability.
For many years the debate about housing centred on rising property prices. Today, the biggest challenge has shifted.
The affordability problem is increasingly driven not by the price of the house itself, but by the cost of financing the purchase. Even if house prices remain stable, higher mortgage rates can add thousands of pounds a year to household costs and make it much harder for first-time buyers to secure the keys to their first home.
That means the housing market may remain subdued until borrowing becomes more affordable. For many would-be buyers, the dream of home ownership has not disappeared—but it has become significantly more expensive to achieve.
