Is Buy-to-Let Investment Still Viable?
Updated: Sep 15
Ask ten people whether buy-to-let is still worth it and you'll get ten confident answers, most of them wrong for your specific situation. The truth sits somewhere between the doom headlines about landlords fleeing the market and the sales pitches insisting nothing has changed. At Smail Property Group (HSPG), we've spent 16 years buying, converting and holding property across the East Midlands, and our honest view is this: buy-to-let is still viable, but only for landlords who treat it as a business rather than a passive bet.
This guide works through what has actually changed, what the real numbers look like in 2026, and how to decide whether it still fits your goals.
Key Takeaways
Yes, but conditionally. Buy-to-let remains viable for investors with a 10-year-plus horizon, a genuine 25%+ deposit, and a willingness to run the numbers on net yield rather than headline gross yield.
The rules changed in 2026, not the concept. The Renters' Rights Act (in force from 1 May 2026) ended Section 21 evictions and moved tenancies to a rolling periodic basis manageable for well-run lets, a bigger shift for landlords who relied on quick turnover.
Tax has tightened twice over. Section 24 already limits mortgage interest relief to a 20% credit, and confirmed government policy will raise property income tax rates to 22%/42%/47% from April 2027.
Location does more work than the national average suggests. A 5% yield in an oversupplied market and a 5% yield in a well-chosen East Midlands street behave very differently once void rates and entry price are factored in.
HMOs generally out-yield single lets but need more capital (from roughly £150k vs. £50k) and more hands-on management.
It's not the right fit for everyone particularly anyone wanting a fully passive income or relying on capital growth alone to rescue a weak cash-flow deal.
What Is Buy-to-Let, and Has It Changed?
Buy-to-let is straightforward on paper: you purchase a property with the specific intention of renting it out rather than living in it, earning income from rent and, potentially, from the property's value rising over time. What's changed isn't the concept it's the operating environment around it.
Ten years ago, a landlord could buy a rental property, sign a letting agent, and check in once a year. That version of the job is largely gone. Today's landlord is managing tax changes, tenancy law reform, mortgage stress tests and energy efficiency deadlines, often simultaneously. None of that makes the investment inherently bad. It changes who it suits and how it needs to be run.
The State of UK Buy-to-Let in 2026: What's Actually Changed
Tenancy Law: The Renters' Rights Act
The Renters' Rights Act came into force for England's private rented sector on 1 May 2026, and it's the biggest shift landlords have faced since the 2016 tax changes. Section 21 "no-fault" evictions are gone. Tenancies now run on a rolling periodic basis rather than a fixed term. Rent increases are limited to once a year and must reflect genuine market rate, with tenants able to challenge unreasonable rises through an independent tribunal. Further provisions including a private rented sector database and a new ombudsman are being phased in through 2026 and 2027.
None of this stops landlords from managing their properties or reclaiming them when they genuinely need to. It does mean evictions require a documented, legally valid reason, and it shifts the balance of the tenancy relationship. For a well-run let, with fair rents and properties maintained to a decent standard, the practical impact is manageable. For landlords who relied on rapid turnover or informal arrangements, it's a bigger adjustment and one worth taking proper advice on, given the penalties for non-compliant paperwork.
Tax: Section 24, Stamp Duty and the 2027 Rise
Since 2020, individual landlords haven't been able to deduct mortgage interest from rental income before calculating tax. Instead, they receive a flat 20% credit against finance costs, regardless of whether they pay tax at the higher or additional rate. This one change has done more to squeeze leveraged landlords' margins than almost anything else on this list.
Stamp duty adds another layer. The surcharge on additional residential property purchases in England and Northern Ireland has stood at 5% since October 2024, on top of standard rates meaning a £250,000 buy-to-let purchase carries roughly £12,500 in surcharge alone, before legal and survey costs.
The next change is already confirmed rather than speculative: from April 2027, income tax rates on rental income are set to rise by two percentage points across the board, to 22% (basic), 42% (higher) and 47% (additional). The associated finance-cost tax credit will also move from 20% to 22%, offering landlords a small partial offset.
Mortgage Rates and Stress Testing
Buy-to-let mortgage rates have settled well above the ultra-low levels landlords enjoyed in 2020 and 2021, with typical two- and five-year fixed deals sitting in the region of 5% to 5.5% through much of 2026. Lenders generally require rental income to cover 125% to 145% of the mortgage interest payment before approving a loan, and most now ask for a minimum 25% buy-to-let deposit, with the sharpest rates reserved for lower loan-to-value borrowing. That combination means the numbers that worked on a 75% mortgage in 2020 often don't stack up the same way today.
Energy Efficiency Requirements
Every rental property will eventually need to meet a minimum EPC rating of C, with the compliance deadline for existing tenancies extending toward the end of the decade. Upgrade costs typically run into several thousand pounds per property depending on the current rating a real budgeting line for anyone buying an older or poorly insulated home.
Is Buy-to-Let Worth It? What the Numbers Actually Say
Most guides on this topic stop at a national average and call it a day. National averages hide the real story. A 5% gross yield in a saturated southern market and a 5% gross yield on a well-chosen East Midlands street are not the same investment once local demand, void rates and purchase price are factored in.
Gross yield annual rent divided by purchase price is a starting point, not an answer. What determines whether a property is genuinely worth buying is the net figure left after mortgage costs, management, maintenance, voids and tax.
Region | Typical Gross Yield (2026) | What Drives It |
London | 4.4% – 5.9% | High purchase price caps yield despite strong rents |
Birmingham | 4.9% – 7.2% | Regeneration areas outperform city average |
Manchester | 5.9% – 8.1% | Strong tenant demand, still below southern price points |
East Midlands (Nottingham, Derby, Leicester) | 6% – 8%+ | Two major universities, lower entry prices, strong rental demand |
North East / North West | 6.8% – 9.6% | Highest headline yields nationally, historically lower capital growth |
Figures above are indicative regional ranges rather than a single verified dataset, and should be checked against current agent and portal data before making a purchase decision.
The East Midlands sits in a genuinely strong position on this table, which is a large part of why HSPG has built its business here rather than chasing more heavily marketed cities. Entry prices remain well below Manchester and Birmingham, rental demand from students, young professionals and families is consistently strong, and yields regularly outperform the national average without the intense competition seen in bigger regional hubs.
The Case For Buy-to-Let
Rental income and cash flow. A well-financed, well-let property still generates monthly income after costs, and that income tends to track inflation over time as rents rise.
Capital growth. UK property has appreciated significantly across long time horizons, though any individual property or short period can move flat or downward — this is a long-term asset class, not a short-term trade.
Leverage. A mortgage lets you control a more valuable asset than your cash alone would buy, amplifying returns on the capital you put in — though it amplifies risk the same way.
Diversification. Property behaves differently from stocks, shares and bonds. Adding it to a portfolio changes your risk exposure, even if it doesn't automatically reduce it.
A tangible, improvable asset. Unlike a share price, you can directly influence a property's value and income: refurbish it, extend it, or reposition it for a different tenant type.
The Real Risks and Costs to Weigh
Compressed margins. Higher mortgage rates combined with Section 24 mean a given gross yield delivers less net cash flow than it did five years ago. The maths has genuinely tightened.
Regulatory and tax exposure. Landlords now manage an active compliance calendar: EPC deadlines, safety certificates, tenancy notices under the Renters' Rights Act, and upcoming database and ombudsman requirements.
Illiquidity. Selling a property can take months, not days, which matters if you ever need to access capital quickly.
Management burden. Even with a letting agent in place, responsibility for the asset ultimately sits with the landlord. Voids, repairs and re-lets tend to cluster rather than spread evenly across the year.
Buy-to-Let vs HMO: Which Delivers Stronger Returns?
This is a question most generic buy-to-let guides skip. A standard let to a single household is the simpler, lower-maintenance option: one tenancy, one set of compliance requirements, and typically the entry point for investors starting from around £50,000 of deployable capital.
An HMO (House in Multiple Occupation) letting individual rooms to multiple tenants generally delivers a meaningfully higher yield, often several percentage points above a comparable single let, because you're collecting several rents from one property. It comes with more moving parts: licensing requirements, higher management involvement, and typically a higher entry point, from around £150,000 in the markets HSPG operates in. For investors with the capital and appetite for a more hands-on strategy, HMOs in areas with strong student or young professional demand Loughborough or Nottingham, for example can outperform a standard single let significantly on a like-for-like basis.
Neither is universally better. The right choice depends on your capital, your risk tolerance, and how hands-off you need the investment to be.
A Practical Framework: Does It Suit You?
This strategy tends to suit investors who are working to a ten-year-plus horizon, can comfortably fund a 25%+ deposit without stretching their finances, are prepared to judge a deal on net yield rather than gross, and are open to structuring the purchase properly including a limited company where it makes tax sense.
It's a weaker fit if your goal is fully passive, hands-off income with no operational involvement at all; if the only property you can realistically afford is a marginal-yield purchase on a high loan-to-value mortgage; or if you're counting on capital growth alone to rescue a deal that doesn't work on cash flow from day one.

Frequently Asked Questions
Is it still viable in 2026?
For landlords who run it properly, with realistic net-yield expectations and awareness of current tax and regulatory obligations yes. It's no longer a passive, semi-retirement strategy for everyone, but it remains a strong option for investors prepared to treat it as a business.
What deposit do I need?
Most mortgages in this category require a minimum 25% deposit, with the most competitive rates reserved for borrowers putting down 35–40%. Lenders will also stress-test whether expected rent covers 125–145% of the mortgage interest payment.
How much capital do I need to start?
Entry points vary by strategy and region. In the East Midlands, a single let typically starts from around £50,000 of deployable capital including deposit and costs; HMO investment generally requires from £150,000 given the larger property size and licensing involved.
Personally, or through a limited company?
For higher-rate taxpayers with mortgaged, growing portfolios, a limited company structure can offer meaningful tax advantages, since companies can still fully deduct mortgage interest before calculating profit. It comes with its own costs including stamp duty on transfers and dividend tax on extraction so professional tax advice before your second purchase (rather than your fifth) is worth the cost.
The Bottom Line
Based on sixteen years of buying, converting and holding property across the East Midlands, our answer is a qualified yes. The easy money of a decade ago is gone, but for investors who run the numbers properly, structure their purchase correctly, and choose their location with real local knowledge rather than a national headline, buy-to-let remains one of the more dependable ways to build long-term income and capital growth in the UK. The investors who struggle are rarely in the "wrong" strategy they're usually the ones who bought without a framework. That's the gap HSPG exists to close.
