First-time buyer mortgage payments exceed rent for 56%

What happened

First-time buyer mortgage payments were higher than previous rents for 56% of tenants who bought a home in September 2026, according to Hamptons. Its analysis puts that share at the highest level in at least a decade. For those households, moving into ownership meant an immediate increase in their regular housing payment, rather than a saving.

Hamptons used Connells Group data to match the mortgage payments taken on by first-time buyers with the rent they had paid before buying. That makes this a comparison of households before and after their move, rather than a comparison between an advertised rental property and an equivalent home for sale. It does not establish that the properties were the same size or type.

The average monthly mortgage payment for a buyer leaving the rental market reached £1,227 in September, Hamptons reported. The analysis also expressed the change as £1.09 in mortgage payments for each £1 previously spent on rent. That describes the reported comparison across buyers, not a payment increase every household should expect.

The balance had been different as recently as July 2026, when 47% of first-time buyers took on a mortgage payment above their former rent, according to Hamptons. September’s figure was nine percentage points higher. Hamptons attributed the changing calculation to recent mortgage rate increases, which have made borrowing more expensive for tenants preparing to buy.

The figures concern monthly mortgage payments, not the complete cost of becoming a homeowner. A repayment mortgage normally includes both interest and repayment of the loan, while ownership also brings responsibilities such as maintenance and buildings insurance. Those differences matter when interpreting a result that shows whether the immediate monthly payment rose or fell.

The background

Hamptons’ historical comparison shows how different the position was towards the end of the low-interest-rate period. In September 2021, 28% of first-time buyers took on mortgage payments above their former rent; in September 2022, the proportion was 33%. Most buyers in both groups therefore avoided the monthly increase now facing a majority.

In September 2022, buyers paid 90p towards their mortgage for every £1 they had previously spent on rent, according to Hamptons. The firm described raising a deposit as the main challenge at that point, against a backdrop of relatively fast house price growth. The latest findings add a separate question: whether the household can comfortably manage the payment after buying.

Deposit size remains an important dividing line in the September 2026 data. Buyers whose mortgage payments exceeded their former rent had an average loan-to-value ratio of 91%, equivalent to a 9% deposit, Hamptons found. Among buyers whose mortgage payments were lower, the average loan-to-value ratio was 83%, equivalent to a 17% deposit.

Loan-to-value measures the mortgage as a proportion of the property’s value. For the same purchase price, a larger deposit means less borrowing, and mortgage pricing commonly varies between loan-to-value bands. However, the Hamptons averages do not establish a deposit threshold that would guarantee a payment below rent for an individual buyer.

Purchase prices and borrowing costs also need to be considered separately. A less expensive home does not necessarily produce a lower monthly payment if the mortgage rate or repayment term changes. Property Pulse UK’s coverage of family home affordability and mortgage rates examines that distinction between the price of a home and the cost of financing it.

What people are saying

Hamptons’ central explanation separates market-wide conditions from individual circumstances. Its analysis identifies interest rates as an important influence on whether buyers generally pay more than they did as tenants, while describing deposit size as a key factor for individual households. The reported findings contain no named individual’s comments or lender forecast.

The firm also found a marked difference between age groups. In September, 67% of first-time buyers in their 40s took on mortgage payments above their previous rent. Their mortgage payments were, on average, 18% higher than the rent they had been paying, according to Hamptons.

Among first-time buyers in their 20s, 47% took on a mortgage payment above their former rent, compared with 58% among buyers in their 30s. These figures describe the buyers who completed purchases in the analysis. They do not measure the position of tenants who wanted to buy but could not proceed.

Hamptons partly linked the older buyers’ results to their choice of larger homes intended to meet their needs for longer. It also pointed to shorter average mortgage terms: 27 years for buyers in their 40s, against 31 years for those in their 30s and 34 years for those in their 20s. Both the home selected and the repayment schedule can therefore affect the comparison with earlier rent.

For a repayment mortgage with the same loan and interest rate, a shorter term generally means higher monthly payments but less interest over the full term. A longer term usually has the opposite effect. The age-group findings should therefore not be read as evidence that younger buyers necessarily face a lower overall borrowing cost.

What happens next

The Hamptons findings provide a September snapshot, not a prediction of the next mortgage rate move. They do not establish when the balance between rent and mortgage payments might reverse again. For a tenant considering a purchase, the relevant comparison is the payment attached to the actual mortgage available, rather than the average paid by earlier buyers.

A practical affordability check starts with the intended purchase price, available deposit, mortgage rate and repayment term. Comparing that resulting payment with current rent can show the immediate change in the household budget. Comparing several terms can also reveal how a lower monthly payment affects the total amount repaid.

Borrowing eligibility is a different question from whether the payment feels manageable. Loan-to-value measures borrowing against the property’s value, while loan-to-income measures borrowing against earnings. Property Pulse UK’s explanation of high loan-to-income mortgage limits covers that separate part of the lending framework.

The agreed purchase price also matters because it helps determine how much a buyer needs to borrow. Buyers can consider comparable local homes and their own budget before making an offer, rather than treating an asking price as a required payment. Coverage of homes selling below asking price provides context on negotiation, without guaranteeing a discount on any particular property.

The wider ownership budget needs room for costs outside the mortgage, including repairs and insurance. Flat buyers may also face service charges under their lease, which are separate from their loan repayment. Property Pulse UK’s guide to home insurance renewal prices explains why an individual quote can move differently from a market average.

Why this matters

For tenants planning to buy, Hamptons’ findings show why saving a deposit and affording ownership need separate calculations. A majority of the buyers studied faced a higher mortgage payment than their previous rent, before allowing for other ownership costs. The differences by deposit size and mortgage term also show why a national average cannot settle an individual decision. Buyers need to compare their current budget with the actual loan and property they are considering.
