Is buy-to-let still worth it in 2026?

What has changed since 2016

Buy-to-let was a different proposition before 2016. Mortgage interest was fully tax-deductible, interest rates were near zero, and the regulatory environment was light. A landlord could buy almost anything, lever it up, and watch the numbers work.

That era is over. The changes that matter most are:

Section 24 came into full effect in April 2020. Higher and additional rate taxpayers can no longer deduct mortgage interest from rental income when calculating their tax bill. Instead they receive a 20% tax credit. For a higher-rate taxpayer with a leveraged portfolio, this can turn a cash-positive investment into a tax loss on paper.

The additional SDLT surcharge was raised to 5% in October 2024, up from 3%. On a £150,000 property this adds £7,500 in upfront costs that need to be recovered from rental income.

Mortgage rates have settled well above the lows of 2020-2021. A 5-year fixed rate for a buy-to-let mortgage at 75% LTV typically sits in the 4.5-5.5% range as of early 2026. The interest coverage ratio (ICR) stress tests used by lenders mean the rental income must cover 125-145% of the mortgage payment at a stressed rate, constraining how much you can borrow.

Legislative burden has grown. The Renters' Rights Act 2025 abolished Section 21 no-fault evictions in England. EPC requirements for rental properties are tightening. Some councils have introduced selective licensing schemes requiring paid licences to let standard houses. None of these make buy-to-let impossible, but they all add cost and complexity.

What still works

The investors doing well in 2026 are not doing what everyone else is doing. They are not buying overpriced flats in London, hoping for capital growth to bail them out of poor cashflow. They are buying cashflow-positive properties in cities with genuine rental demand, at genuine yields.

The numbers that make buy-to-let viable in 2026:

Gross yield of 7% or above gives you enough margin to absorb mortgage costs, voids, maintenance, and management fees and still produce positive net cashflow. At 5% gross yield in most of the country, you are likely subsidising your tenant.

Postcodes in Newcastle, Sunderland, Bradford, Sheffield, and parts of the Midlands regularly deliver 7-9% gross yields on terraced houses and small HMOs. These are not glamorous markets. The properties are modest. But the maths works.

Using a limited company structure sidesteps Section 24 entirely. The mortgage interest remains fully deductible as a business expense within a limited company, and corporation tax rates are lower than higher-rate income tax. The trade-off is a smaller choice of mortgage products and typically higher rates, plus the cost of running a company and extracting dividends. But for investors building a portfolio, the maths increasingly favours the limited company route.

BRRR (Buy, Refurbish, Refinance, Rent) remains a genuine strategy for investors who can manage a refurb and tolerate the bridge financing period. Buying below market value, adding value through renovation, then refinancing at the improved value allows capital to be recycled into the next deal. This requires skills and time, but it produces better returns than simply purchasing and renting.

Who it suits and who it does not

Buy-to-let is not a passive investment. Even with a managing agent, you are running a business. You will deal with voids, maintenance calls, compliance changes, and the occasional difficult tenant. You need time, a contingency fund, and the temperament to handle problems.

It suits investors who: - Are in it for the long term. Property is illiquid. Selling takes months and costs money. - Have capital they can afford to lock up. - Are comfortable with complexity - tax, mortgage, tenancy law. - Have a strategy. Area selection, property type, and pricing discipline all matter.

It does not suit investors who: - Need returns that are liquid within five years. - Are higher-rate taxpayers holding property in their personal name with significant leverage. - Are buying in areas with low rental demand because prices look cheap. - Expect capital growth in the near term to compensate for poor yield.

There is no universal answer to whether buy-to-let is worth it. There is only the answer for your specific situation: your tax position, your capital, your time horizon, and the specific property you are considering at the price you are paying.

The honest bottom line

If someone asks whether buy-to-let is worth it, the truthful answer is: it depends entirely on the deal.

Property bought at auction below market value in a high-yield northern city, inside a limited company, at 7%+ gross yield, with a clear-eyed view of all costs, can still produce solid risk-adjusted returns. It is not easy money. It requires knowledge, discipline, and capital.

Property bought at 4% yield in a southern city, in personal name, at full asking price, with an interest-only mortgage, is likely to produce negative real returns after tax and inflation.

The narrative that property always wins is lazy and harmful. So is the narrative that it is all broken and not worth considering. The truth sits between those positions, and it is specific to each deal.

Use the yield calculator and cashflow calculator to stress-test any property you are considering before you commit. Look at the numbers with voids and maintenance included, not just the best-case scenario. If the deal still works under reasonable stress assumptions, it might be worth pursuing.
