With mortgage rates back around 6% and government borrowing costs under pressure, homebuyers face an uncomfortable question: buy now, wait for a better deal, or risk taking on a debt that could become difficult to manage?
Buying a home is one of the biggest financial commitments most people will make. It is also one of the easiest decisions to justify emotionally. People find a property they like, imagine living there and start working out how to make the figures fit.
But the figures deserve particularly careful attention now.
UK government borrowing costs have risen sharply, international bond markets are unsettled, and mortgage lenders have been increasing some of their rates.
On 5 October, the average two-year fixed mortgage rate was reported at 5.98%, while the average five-year rate reached 6%. The cheaper deals that borrowers had hoped to find have become much harder to come by.
Nobody can say with certainty whether mortgage rates will rise further or fall again. But that uncertainty makes one question especially important: should you delay taking on a new mortgage?
The answer depends on whether you can afford the risk
There is no universal answer. Someone who needs to move for work or family reasons may have little choice but to proceed. A first-time buyer who has found a suitable property, has a substantial deposit and can comfortably afford the repayments may decide that buying now makes sense.
But someone stretching their finances to the limit, relying on interest rates falling soon, or expecting their income to improve may be taking a much greater risk.
The important question is not simply whether a lender will approve the mortgage. It is whether you can afford to live with it if circumstances turn against you.
A lender's approval does not guarantee that a mortgage is comfortable for your household budget.
What would another two percentage points mean?
Consider a repayment mortgage of £200,000 over 25 years.
The following figures are illustrative, assuming the interest rate applies throughout the calculation period and ignoring fees. They show how sensitive monthly payments are to changes in rates.
Interest rate Monthly repayment
4% £1,056
6% £1,289
7% £1,414
8% £1,544
At 6%, the monthly payment is about £233 higher than at 4%. At 8%, it is about £488 higher.
That is an additional £5,856 a year compared with the 4% example.
For a household with plenty of spare income, that may be manageable. For a family already struggling with food, fuel, childcare and other bills, it could be the difference between keeping up with payments and falling into financial difficulty.
And the figures cover only the mortgage. They do not include Council Tax, insurance, repairs, energy bills or the other costs of running a home.
The test every prospective borrower should take
Before signing, calculate what your repayments would be at the rate being offered and then at rates one and two percentage points higher.
Ask yourself:
Could we still afford the payments if interest rates rose?
What if one of us lost a job or had to reduce working hours?
Could we cope with a major car repair, a new boiler or another unexpected expense?
Would we still have enough money for food, heating and ordinary family life?
Would we have any savings left after paying the deposit, legal costs and moving expenses?
If the answer depends on everything going right, the mortgage may be too large for comfort.
This is particularly important for buyers with small deposits, high loan-to-income ratios or employment that is insecure or dependent on the wider economy.
Should you wait for house prices or mortgage rates to fall?
Waiting has advantages, but it is not a guaranteed winning strategy.
Mortgage rates could fall if inflation eases and financial markets become more settled. House prices could also weaken if buyers become less able or willing to borrow.
But the opposite could happen. Rates might rise further, house prices could remain firm in the area you want to buy, or a suitable property might become unavailable.
There is also a cost to waiting if you are paying rent while trying to save a larger deposit.
The sensible approach is not to try to predict the exact bottom of the housing market. It is to decide what you can afford and whether the property meets your needs at today's price and today's borrowing cost.
If a purchase only makes sense on the assumption that mortgage rates will soon fall, waiting and reviewing the situation may be preferable to committing yourself to a debt you cannot comfortably service.
Fixed rates offer certainty, not necessarily a bargain
A fixed-rate mortgage protects the borrower against changes in the interest rate during the agreed fixed period. That can make household budgeting easier.
But fixing at today's rate does not guarantee that you have secured the cheapest deal. If rates subsequently fall, you may be paying more than someone who takes out a mortgage later. Depending on the contract, leaving a fixed-rate deal early may also involve an early repayment charge.
A tracker mortgage may become cheaper if Bank Rate falls, but payments can increase if it rises. A variable-rate mortgage carries its own risks.
There is no mortgage product that removes every uncertainty. The choice is about the balance between cost, flexibility and certainty.
Before choosing a deal, compare the total cost, including arrangement fees, the length of the introductory period and what happens when it ends. An independent mortgage adviser can help assess the available options.
Do not confuse a mortgage offer with a household safety margin
A buyer might be offered a mortgage because their income and outgoings satisfy the lender's assessment. But life rarely follows a neat spreadsheet.
Energy prices can rise. Cars break down. Children need things. Household appliances fail. Work can become less secure.
The same bond market pressures that are increasing government borrowing costs may also affect businesses and the wider economy. If growth weakens, households could face higher borrowing costs at the same time as less secure employment.
That is why having savings left after moving can be just as important as finding the lowest available mortgage rate.
A buyer who uses every penny for the deposit and moving costs may have little protection against an unexpected bill.
What about people who already have a mortgage?
Existing homeowners do not necessarily need to panic. If you have a fixed-rate mortgage, your interest rate normally remains unchanged until the deal ends.
However, if your fixed period expires in the coming months, it is worth contacting your lender early and comparing available options. MoneyHelper advises borrowers to start reviewing their options well before their current deal ends. Some lenders allow customers to reserve a new rate and change it later if a better deal becomes available, subject to the lender's rules.
Do not simply allow a fixed deal to expire without checking what happens next. The lender's standard variable rate may be considerably more expensive.
If you are already struggling with payments, contact your lender before falling into arrears. There may be options worth discussing.
The final question: do you need to buy now?
For some households, the answer will be yes. A necessary move, a secure income, a manageable mortgage and a financial cushion can make buying reasonable even when rates are uncertain.
For others, particularly those borrowing at the limit of what they can afford, delaying may be the safer option while they build their deposit, reduce other debts or see how the market develops.
The danger is not simply that mortgage rates might rise. It is taking on a long-term commitment that leaves no room for anything to go wrong.
Before signing, ask yourself one final question: if mortgage rates were two percentage points higher when my deal ends, could I still afford this home without sacrificing the essentials?
If the honest answer is no, think carefully before proceeding. A property can be the right home and still come with the wrong mortgage.
The aim is not to frighten people away from buying a home. It is to make sure that when they do buy, they can afford to stay in it.
