Portfolio Landlord or Exit? How to Make the Numbers Work in the Current Market
Key Takeaways
- An estimated 93,000 UK buy-to-let landlords exited the market in 2025, but sell-offs have slowed sharply in early 2026, falling 45% year-on-year in Q1
- 5.8% gross yield sounds reasonable - but for a higher-rate taxpayer with a 75% LTV mortgage at current rates, that can translate to negative cash flow after Section 24 and compliance costs
- From April 2027, property income tax rates rise to 22%, 42% and 47% - confirmed in the Autumn Budget 2025. The mortgage interest relief credit rises with it, from 20% to 22%
- Around 80% of new buy-to-let mortgages are now taken out through limited companies - and the April 2027 changes widen the gap between personal and corporate ownership considerably
- Landlords who stay and focus on tenant retention consistently outperform those chasing yield through constant re-letting - a void on a £1,450/month property costs £1,500-£2,500 all in
The numbers on being a UK private landlord in 2026 are not straightforward. Gross yields have held up: Zoopla puts the UK average at 5.8%, and average rents edged down just 2% to £1,450 per month in Q1 2026 while remaining close to record highs, according to TwentyCi data. On the face of it, staying in the market still makes financial sense for many landlords. But gross yield and net return are not the same thing, and the gap between them has widened considerably over the past three years.
An estimated 93,000 buy-to-let landlords exited the market in 2025, according to property purchasing firm LandlordBuyer. The exodus contributed to a significant rise in households at risk of homelessness. Yet in early 2026 the wave is moderating: the share of homes coming to market that were previously rented fell from 22.5% in Q1 2025 to 12.4% in Q1 2026, a 45% year-on-year reduction, according to TwentyCi. The question facing landlords who have stayed is not whether they made the right call to hold, but whether they are managing their portfolios in a way that makes staying financially sustainable.
The Real Net Yield Picture
Gross yield of 5.8% is the number landlords quote when the conversation is going well. It is not the number that pays the mortgage. The table below runs the same property through four scenarios - basic rate taxpayer, higher rate taxpayer now, higher rate taxpayer after April 2027, and a limited company - to show what 5.8% gross actually becomes in each case. The results are instructive.
| Item | Basic rate Personal ownership |
Higher rate Personal (2026) |
Higher rate Personal (2027+) |
Limited company |
|---|---|---|---|---|
| Starting position | ||||
| Property value | £250,000 | £250,000 | £250,000 | £250,000 |
| Annual gross rent (5.8%) | £14,500 | £14,500 | £14,500 | £14,500 |
| Costs and tax | ||||
| Mortgage interest (75% LTV at 5.5%) | £10,313 | £10,313 | £10,313 | £10,313 |
| Allowable expenses (management, insurance, compliance, maintenance) | £2,800 | £2,800 | £2,800 | £2,800 |
| Taxable profit (Section 24 applies to personal: mortgage NOT deductible) |
£11,700 | £11,700 | £11,700 | £1,387 |
| Income / corporation tax on profit | £2,340 | £4,680 | £4,914 | £263 |
| Mortgage interest tax credit (20% credit, rising to 22% in 2027; companies deduct fully) |
-£2,063 | -£2,063 | -£2,269 | n/a |
| Net tax payable | £277 | £2,617 | £2,645 | £263 |
| Net annual cash after all costs and tax | +£1,110 | -£1,230 | -£1,258 | +£1,124 |
| Net yield on property value | 0.44% | -0.49% | -0.50% | 0.45% |
Illustrative example. Assumes 75% LTV mortgage at 5.5% interest rate, 5.8% gross yield, allowable non-mortgage expenses of £2,800/year (management at 10%, insurance, annual compliance costs, maintenance allowance). Personal tax at current basic rate 20% or higher rate 40%; April 2027 rates 22%/42% as confirmed in Autumn Budget 2025. Limited company at small profits corporation tax rate of 19%. Void periods, capital expenditure and mortgage arrangement fees excluded for comparability. Always seek accountancy advice on your specific position.
The headline is the second column. A higher-rate taxpayer on a property that looks profitable - 5.8% gross yield, reasonable expenses, standard 75% LTV mortgage - is likely cash-flow negative after Section 24, expenses and tax. The property may be building capital, but it is costing money every month. This is the calculation many landlords have not run, or have not run recently enough. Gross yield is a marketing number. Net cash is the operating reality.
The April 2027 tax change makes this marginally worse, not dramatically so. The real story of 2027 is not the 2% rate increase but the compounding effect of Section 24 already in place, higher mortgage rates since 2022, and frozen income tax thresholds that have pushed more landlords into the higher-rate band. Around 500,000 additional people entered the higher-rate tax bracket between 2024/25 and 2025/26 alone (Champion Accountants, 2026). Some of them are landlords who were previously basic rate and whose position now looks very different.
The Geography Problem With 5.8%
The UK average yield of 5.8% masks enormous regional variation. For landlords in London, the real number is considerably lower. For those in the North of England, it may be considerably higher. The table above uses the national average - but where your property sits determines which scenario is actually your reality. If your gross yield is 3.5–4%, the higher-rate personal ownership column gets significantly worse.
Regional gross yield ranges are indicative based on Zoopla and Hamptons data, 2025/26. Net yields vary significantly by mortgage position, tax status and local compliance costs.
"For small, private landlords in particular, property now feels less like a long-term investment and more like a heavily regulated business with rapidly diminishing returns."
Robin Edwards, Property Buying Agent, Curetons, December 2025The Limited Company Question - Why 80% of New Purchases Are Now Through Companies
The yield table above contains a detail worth sitting with. A higher-rate taxpayer holding a property personally is generating negative cash flow of around £1,230/year on a property that a limited company would generate positive cash flow of £1,124/year on. That is a difference of over £2,350 per property per year - before accounting for any void periods. With a portfolio of five properties, that gap is over £11,750 annually.
The reason is structural. Limited companies are not subject to Section 24. They can deduct 100% of mortgage interest as a business expense before calculating profit. That profit is then taxed at corporation tax rates - currently 19% on profits below £50,000, rising to 25% above £250,000 - rather than at 40–47% personal income tax rates. From April 2027, when personal property income rates rise to 42% for higher-rate taxpayers while limited company rates remain unchanged, the gap widens further. This is why, according to UK Finance data, around 80% of new buy-to-let mortgage applications are now made by limited companies (Property Passport UK, 2026).
| Factor | Personal Ownership | Limited Company (SPV) |
|---|---|---|
| Tax on rental profits | Disadvantage 40–42% (higher rate) or 20–22% (basic rate) from April 2027 |
Advantage 19–25% corporation tax |
| Mortgage interest | Disadvantage Not deductible - 22% tax credit only (from April 2027) |
Advantage 100% deductible as a business expense |
| Reinvesting profits | Disadvantage Tax paid at personal rate before reinvestment |
Advantage Profits retained in company taxed at 19–25% - more left to deploy |
| Mortgage rates | Advantage Slightly lower - personal BTL mortgages typically 0.3–0.5% cheaper |
Note Slightly higher - limited company BTL mortgages typically 0.3–0.5% premium |
| Accountancy costs | Advantage Lower - personal tax return typically £500–750/year |
Note Higher - company accounts typically £850–2,000/year |
| Transferring existing properties | N/A Not applicable - already held personally |
Watch out Typically triggers SDLT and potential CGT - seek professional advice before acting |
| Best suited to | Basic rate taxpayers, small portfolios, landlords who need rental income now | Higher-rate taxpayers, portfolio growth strategy, landlords reinvesting rather than extracting |
Incorporation is not automatically the right answer. Transferring existing properties into a limited company typically triggers Stamp Duty Land Tax and potentially Capital Gains Tax on the transfer - a significant one-off cost that can take years of tax savings to recover. For landlords already holding properties personally, the decision to incorporate requires detailed modelling with an accountant who understands the specific numbers. For new purchases, the calculus is more straightforward. The administration gap between personal and company ownership is also narrowing: Making Tax Digital for Income Tax becomes mandatory from April 2026 for landlords with income over £50,000, meaning additional compliance requirements apply regardless of structure.
Why Tenant Retention Is Now the Single Most Important Lever
For landlords who have done the maths and concluded that staying makes sense, the operational priority has shifted decisively. With Section 21 abolished under the Renters' Rights Act 2025, the ability to end a tenancy quickly and re-let to a higher-paying tenant - a strategy many landlords used to maximise yield during the rent inflation of 2021 to 2024 - is gone. The new system makes tenant quality and tenancy stability far more valuable than marginal rent increases achieved through turnover.
The financial case for retention is clear. A void period of just four weeks costs the equivalent of one month's rent in lost income, immediately wiping out any yield advantage gained from a rent increase at re-letting. Add the cost of re-referencing, re-marketing, potential redecoration and letting agent fees, and the total cost of a tenancy turnover on a property letting at £1,450 per month is typically in the range of £1,500 to £2,500. A tenant who renews is worth considerably more than a slightly higher rent on a new letting.
The English Private Landlord Survey, published by MHCLG in December 2025, found that 31% of landlords plan to reduce their portfolio size and 16% are considering selling all rental properties within two years. But landlord sales are now the single biggest cause of tenancy endings, responsible for nearly three times as many cases as any other reason, according to the NRLA. For landlords committed to staying in the market, the competitive advantage is increasingly about being the kind of landlord tenants want to stay with: responsive, fair, and supportive of tenant financial wellbeing.
Two further tools are worth factoring into a retention strategy. Rent guarantee insurance, which costs approximately 3–4% of annual rental income, protects against non-payment under the new periodic tenancy regime where Section 21 is no longer available as a backstop. It is not widely used but its value has increased now that the route to regaining possession is slower and more process-intensive. And platforms that support tenant financial wellbeing - giving tenants access to cashback and discounts on everyday spending - are increasingly used by landlords as a low-cost, high-signal retention tool that demonstrates genuine care for the tenant's situation rather than just their rent payment.
The Tenant Retention Maths
Preventing one void period per property saves £1,500–£2,500 in direct costs. On a portfolio of five properties, if good tenant management prevents one void per property every three years, the saving over a decade is in the region of £25,000–£40,000 - equivalent to several years of tax savings from incorporation. Tenant retention is not a soft metric. It is a financial lever that most landlords have not quantified.

The landlords best positioned in the current market share several characteristics. They have modelled their net yield accurately, including all compliance costs and the forthcoming tax changes. They manage their properties professionally, either directly or through agents, with clear systems for referencing, rent reviews and maintenance. They have considered whether their ownership structure - personal or limited company - is optimised for their tax position and growth ambitions. And they treat tenant relationships as a long-term asset, not a short-term transaction.
Only 6% of rental properties sold in Q2 and Q3 2025 subsequently returned to the lettings market, according to TwentyCi analysis of over 492,000 transactions. The vast majority were absorbed by owner-occupiers. Private rental stock continues to shrink, demand remains elevated, and the landlords who remain are letting into a market where quality tenants are actively seeking stable, well-managed properties. That is a strong position - for landlords who run their portfolio accordingly.
Five Questions to Run Before You Decide
If you are at a decision point, these are the five questions worth working through properly before acting in either direction.
-
1What is your actual net yield, not your gross yield? Run the table above on your own numbers - your mortgage rate, your LTV, your tax band, your real expenses. If the answer is negative, is it because of a fixable structural issue (tax status, mortgage product, management cost) or because the underlying property economics no longer work?
-
2Are you in the right ownership structure for your tax band? If you are a higher-rate taxpayer with three or more properties and you are not holding through a limited company, have you modelled the difference? The April 2027 rate changes make this more urgent. Get an accountant who specialises in property to run the numbers before the changes take effect.
-
3Have you accounted for Making Tax Digital? From April 2026, landlords with combined property and self-employment income over £50,000 must comply with MTD for Income Tax (MTD ITSA), requiring quarterly digital submissions to HMRC. This is not optional and the administration cost is real. Factor it into your annual running costs.
-
4What is your EPC position and what will it cost to fix? The 2030 EPC C deadline is confirmed, with a £10,000 cost cap per property and fines of up to £30,000 for non-compliance. Expenditure from October 2025 already counts toward the cap. If you have F or G-rated properties, or properties likely to fall short of C under the new Home Energy Model methodology from 2029, the cost of compliance affects the investment case now.
-
5What does tenant turnover actually cost you? Calculate your average void period, your re-letting costs and your re-referencing costs. Then calculate what reducing churn by one tenancy per property over the next five years would add to your net return. For most portfolios, this number is larger than any single operational saving. If you are not actively investing in tenant retention, you are leaving money on the table.
What This Means for Private Landlords in 2026
The question for every landlord right now is not "should I stay in the market" in the abstract, but whether their specific portfolio is generating a sustainable net return, and whether they are managing it in a way that protects that return over the long term. The answer to the first part requires proper modelling - ideally with an accountant who understands Section 24, the April 2027 rate changes, and the limited company question. The answer to the second requires a genuine focus on tenant relationship quality, which is the most cost-effective tool available for reducing void periods, preventing arrears and building the kind of tenancy stability that makes rental property a real asset.
Landlords who exit in 2026 because they have properly modelled their position and concluded the numbers do not work are making a rational decision. Landlords who exit without doing that work - or who stay without addressing the ownership structure and operational headwinds - are taking an unnecessary risk in either direction. The market rewards clarity and professionalism. It always has.
