Is Buy to Let Still Profitable in the UK?
Buy to let has long been one of the most popular ways to invest in UK property. But with rising mortgage rates, tax changes, and tighter regulations, many investors are now asking the same question: is buy to let still profitable in the UK?
The honest answer is yes — but only when the numbers are modelled realistically. The days of relying on simple yield percentages or headline “best area” lists are largely gone. Today, profitability depends on location, finance structure, ongoing costs, and how well an investment performs under real-world conditions.
In this guide, we break down what has changed for buy-to-let investors, share realistic profit examples, and explain how to assess whether a property actually stacks up. We also link to a buy-to-let investment simulator that allows you to model returns in far more detail than a basic calculator — helping you make informed decisions before committing capital.
What Has Changed for Buy-to-Let Investors?
Buy-to-let investing hasn’t stopped working — but the landscape has changed significantly over the past few years. Many of the assumptions that made buy to let feel straightforward a decade ago no longer apply in the same way today.
One of the biggest shifts has been higher mortgage rates, which have increased monthly costs and made cash flow more sensitive to interest rate changes. At the same time, tax treatment for landlords has become less favourable, particularly for higher-rate taxpayers, meaning headline profits can look very different once tax is taken into account.
Investors are also facing greater regulatory and compliance requirements, including licensing, energy efficiency standards, and ongoing property management obligations. While none of these changes make buy to let unworkable, they do mean that profitability now depends far more on accurate forecasting and realistic assumptions rather than simple yield calculations.
This is why understanding how a property performs under real-world conditions is now more important than ever.
So, Is Buy to Let Still Profitable in the UK?
Yes — buy to let can still be profitable in the UK, but it no longer works as a one-size-fits-all investment. Profitability today depends far more on how you invest than simply where you invest.
Investors who focus only on headline yields or outdated assumptions often find that real-world returns fall short once mortgage costs, tax, and ongoing expenses are factored in. However, those who take a more realistic, data-led approach are still achieving strong long-term outcomes.
In practical terms, buy to let tends to work best when properties are purchased at sensible price-to-rent ratios, financed appropriately, and assessed using realistic cash flow modelling rather than simple yield calculations. This shift is why many investors now stress-test deals before committing — to understand how an investment performs under different conditions, not just in ideal scenarios.
The difference between a profitable buy-to-let and a disappointing one often comes down to how accurately the numbers are assessed before purchase.
Realistic Buy-to-Let Profit Examples (UK)
Below are three illustrative buy-to-let scenarios to show how profitability can change depending on rent achieved, costs, and financing. These are not guarantees — they’re examples designed to reflect how deals behave in the real world.
Example 1: Entry-level Buy-to-Let (Lower Purchase Price)
IllustrativeConservative
Higher costs, cautious rent
- Net cash flow: modest / close to break-even
- Stress-tested for rate + cost increases
- Works best with long-term hold mindset
Optimistic
Stronger rent, stable costs
- Net cash flow: positive
- More resilient if demand stays strong
- Profitability improves with good management
Example 2: Mid-range Buy-to-Let (Balanced Approach)
IllustrativeConservative
Interest + maintenance up
- Net cash flow: small positive / neutral
- Margins depend on finance structure
- Good deal selection is essential
Optimistic
Healthy rent-to-price ratio
- Net cash flow: comfortably positive
- More flexible for contingency reserves
- Solid base for portfolio building
Example 3: Higher-value Buy-to-Let (More Rate Sensitive)
IllustrativeConservative
Higher borrowing costs
- Net cash flow: can be tight
- More sensitive to rates and voids
- Best with strong tenant demand areas
Optimistic
Stable occupancy + rent
- Net cash flow: positive with good structuring
- Lower stress if demand is consistent
- Can perform well with long-term holding
Tip: The same property can look profitable on paper but disappoint in reality if finance, tax, and ongoing costs aren’t modelled properly.

Frequently Asked Questions
Is buy to let profitable without a mortgage?
It often can be, because borrowing costs are removed and cash flow becomes more predictable. The trade-off is a lower percentage return on capital if you tie up a large amount of cash. Many investors compare both options by modelling scenarios before deciding.
What yield is considered “good” for buy to let in the UK?
There isn’t one universal number. A “good” yield depends on your finance structure, costs, tax position, and local demand. In higher-cost areas, lower yields can still make sense if long-term growth is a priority. In yield-led areas, the key is ensuring the deal works after realistic expenses, not just on gross yield.
What’s the biggest factor that affects buy-to-let profitability today?
For most investors, it’s the relationship between rent, borrowing costs, and ongoing expenses. Small changes in interest rates, void periods, maintenance, or management can materially impact returns. That’s why stress-testing scenarios and modelling cash flow is now essential.
