UK Landlord Property Sales Losses Surge 32% to £1.15bn as New Tax Pressures Hit Buy-to-Let Market

29 October 2026 | UK Property News

UK landlord property sales losses have surged by 32% to £1.15 billion, according to newly released HMRC figures, highlighting mounting financial pressure on Britain’s buy-to-let investors as falling property values, rising ownership costs and tighter rental regulations reshape the housing market.

The figures, obtained by Bowmore Wealth Group through a Freedom of Information request, reveal that landlords and residential property investors reported £1.15 billion in realised losses during the 2024/25 tax year, compared with £870 million in 2023/24.

The £280 million increase comes as property investors face another potential squeeze following the Autumn Budget delivered on 28 October 2026, which announced further increases in income tax on rental profits from April 2027.

Although the newly released figures cover an earlier tax year, the latest evidence suggests financial pressures have continued into 2026, particularly in London, where flat prices have fallen more sharply than the wider housing market.

The findings raise fresh questions about the profitability of buy-to-let investment, the future supply of rental homes and whether more landlords will decide to sell rather than absorb additional costs.

Why Are UK Landlords Losing Money on Property Sales?

The latest Bowmore Wealth Group research, published on 27 October, identifies £1.15 billion in crystallised losses on residential property investments.

These are losses reported when investors sell their properties, rather than temporary reductions in the estimated value of homes they continue to own.

The figures do not include unrealised losses on properties still held by landlords, meaning the total exposure to falling valuations could be substantially greater.

However, the £1.15 billion figure does not represent the buy-to-let sector’s overall net loss. Profits made by landlords selling other properties are excluded, and the data does not show how many individual investors suffered losses.

David Floyd, Head of Private Clients at Bowmore Financial Planning, believes changes in the relative attractiveness of property investment are encouraging landlords to reassess their portfolios.

He said investors were increasingly comparing relatively modest net rental yields with returns available from global stock markets and UK government bonds.

Floyd also warned:

“The Renters’ Rights Act may have prompted buy-to-let investors to sell up even if it means taking a loss.”

His comments reflect growing concern that the combination of maintenance expenses, mortgage repayments, tax obligations and property management responsibilities is reducing the financial appeal of smaller rental portfolios.

For landlords who purchased properties during stronger market conditions, the situation can be particularly difficult.

An investor who bought a flat at a premium, subsequently faced higher mortgage costs and then decided to sell into a weaker market could experience a capital loss despite having collected rental income during ownership.

Nevertheless, a property selling below its purchase price does not necessarily mean the entire investment was unprofitable, since previous rental income and other costs must also be considered.

London Property Losses Raise Concerns for Buy-to-Let Investors

London has emerged as one of the most challenging markets for investors seeking to sell residential properties.

According to the latest Office for National Statistics housing figures, published on 21 October, average London property prices declined by 2.2% in the 12 months to August 2026.

Over the same period, average flat prices in the capital fell by 5%, highlighting a significant difference between the performance of apartments and houses.

Across the UK, average property prices increased by just 0.9% annually to £273,000, demonstrating how the national market has slowed.

Separate research from e.surv Chartered Surveyors presents an even more striking picture.

Its October 2026 House Price Index found that nearly four in ten London flats sold during the 12 months to August 2026, after being owned for between five and ten years, changed hands below their previous recorded purchase price.

The proportion was approximately one-third in the South East and East of England, compared with just over one-quarter across Great Britain.

The research covers qualifying flat resales generally, not exclusively landlord-owned properties, but it illustrates the weakness affecting an important segment of the buy-to-let market.

Rob Owens, Head of Research at e.surv, said:

“Flats remain one of the clearest areas of weakness.”

Owens identified building safety concerns, tenure arrangements and service charges as factors requiring greater attention from buyers and lenders.

For landlords owning leasehold apartments, these issues can translate into higher annual expenditure and a smaller pool of potential purchasers.

In some cases, investors may face difficult choices between accepting a discounted offer, funding additional improvements or continuing to hold a property whose capital value has declined.

The weakness of London’s flat market is particularly significant because apartments account for a much larger proportion of transactions in the capital than elsewhere in Britain.

Renters’ Rights Act Adds Further Uncertainty

The Renters’ Rights Act has also become an important consideration for landlords evaluating whether to retain or dispose of rental properties.

Major provisions took effect in England on 1 May 2026, including the abolition of Section 21 no-fault evictions and changes to the legal process for ending tenancies.

Landlords must now rely on valid statutory possession grounds. These include circumstances in which an owner genuinely intends to sell a property, although restrictions and notice requirements apply.

The legislation also limits ordinary rent increases to once per year and establishes additional protections for tenants.

For investors already experiencing reduced net yields, the administrative responsibilities and potential delays involved in recovering possession may affect the decision to sell.

However, the timing of the HMRC figures requires an important distinction.

The £1.15 billion in reported losses relates to 2024/25, whereas the main rental reforms came into force in May 2026. Consequently, those historic losses cannot establish that the legislation caused the increase.

Expectations of future regulation may have influenced earlier decisions, but that effect has not been quantified in the figures.

There is also evidence that landlord sales have recently moderated.

Hamptons reported in July that 9.2% of homes listed for sale in June 2026 had been advertised for rent within the previous five years, down from 11.3% in June 2025.

This suggests that the market is undergoing a shift in investment behaviour rather than a uniform exit by landlords.

Some Investors Are Taking Advantage of Falling Asking Prices

While existing landlords are facing losses, buyers with available capital are finding opportunities.

Research published by Hamptons in August showed that buy-to-let investors accounted for 14.1% of home purchases across Great Britain during July 2026.

The analysis also revealed that 56% of investor offers were at least 10% below the original asking price, compared with 45% a year earlier.

Landlords purchasing in cash were particularly aggressive, with 63% of their offers coming in at least 10% below the initial asking price.

David Fell, Lead Analyst at Hamptons, explained:

“When the market slows, seasoned investors rarely stand on the sidelines for long.”

According to Fell, experienced investors are using their cash reserves and chain-free purchasing positions to negotiate more favourable prices.

The changing balance of power between buyers and sellers could create opportunities for financially stronger landlords while increasing pressure on owners who need to dispose of properties quickly.

Hamptons found that 27% of investor offers at least 10% below the initial asking price were accepted in July, compared with 18% a year earlier.

For leasehold properties, the acceptance rate reached 41%, further demonstrating the difficulties facing some flat sellers.

However, accepting an offer below the asking price is not necessarily the same as selling at a financial loss. Whether a landlord loses money depends on their original acquisition cost, allowable expenses and other financial circumstances.

Autumn Budget 2026 Brings Another Tax Increase for Landlords

The latest losses have attracted attention just as the Government announced further changes to the taxation of rental income.

The Autumn Budget 2026, delivered on 28 October, confirmed an additional two-percentage-point increase in income tax rates applicable to property income from 6 April 2027.

Combined with increases previously announced in 2025, the new property income tax rates will be:

• 24% for basic-rate property income.
• 44% for higher-rate property income.
• 49% for additional-rate property income.

The announced rates apply to relevant property income in England, Wales and Northern Ireland and are scheduled to be implemented through the Finance Bill 2026-27.

They concern tax on property income, not the Capital Gains Tax rates charged when an investment property is sold.

For individual landlords, the changes create another reason to review expected net returns, particularly where mortgage finance and ongoing maintenance already consume a substantial proportion of rental receipts.

Legal specialists Richard Woolich and Natalie Groves, writing in DLA Piper’s 28 October real estate Budget analysis, described the further property income tax increases as a significant development in the reduction of returns available to private landlords.

The additional tax burden could influence future investment decisions, although its impact on property sales will depend on market conditions and individual circumstances.

Meanwhile, rental income itself continues to rise.

ONS figures show that average monthly private rents across the UK increased by 3.8% in the year to September 2026, reaching £1,406.

Higher rents may provide some financial relief for landlords, but they do not automatically translate into stronger profits when borrowing, insurance, repairs, management fees and taxation are also increasing.

What Happens Next for UK Landlords and Property Prices?

The rise in reported landlord property sales losses highlights the importance of evaluating an investment on its overall financial performance rather than relying solely on potential house price appreciation.

Landlords considering selling must account for current valuations, outstanding mortgages, selling costs, rental income, maintenance obligations and potential tax consequences.

Where a qualifying capital loss arises, HMRC guidance explains that allowable losses can generally be used to reduce taxable capital gains, subject to the applicable rules.

Claims can ordinarily be made up to four years after the end of the tax year in which the disposal occurred.

However, capital losses are not generally available to offset ordinary rental income, and investors should distinguish between an economic loss and a loss allowable for Capital Gains Tax purposes.

For tenants, the broader question is whether sustained pressure on landlords will affect the availability of rental accommodation.

If a greater number of owners decide to sell to owner-occupiers without equivalent investment in new rental homes, the supply of privately rented properties could tighten.

On the other hand, the latest Hamptons figures demonstrate that some investors remain active and are using weaker market conditions to acquire properties at discounted prices.

The eventual outcome will depend on interest rates, housing demand, the implementation of rental reforms and how investors respond to the tax changes scheduled for April 2027.

For now, the £1.15 billion in recorded property disposal losses provides a warning about the financial risks facing parts of Britain’s buy-to-let sector.

With London flats showing particular weakness and another increase in property income taxation approaching, the market faces a period in which careful financial planning may matter more than expectations of rapid house price growth.

The latest evidence does not suggest every landlord is losing money or abandoning property investment. It does, however, show that the economics of buy-to-let ownership are changing, creating difficult decisions for established investors and new opportunities for buyers with sufficient capital.
