In my last article, written in February and published in March, I set out a view that the buy-to-let (BTL) sector had made a purposeful and steady start to 2026, based on the application activity, adviser engagement and landlord behaviour we were seeing at the time.
By the time that piece appeared, it’s fair to say the wider market had shifted quite sharply, with volatility feeding through into mortgage pricing, product withdrawals and a more cautious tone across the sector.
That contrast highlights a simple but important point, which is that writing even a few weeks in advance in the current climate can leave any market view looking out of date almost as soon as it is published, particularly when external factors are moving as quickly as they have done in recent months.
However, it is also worth stepping back and looking at the data that sits behind those earlier observations, because the latest UK Finance figures for Q4 2025 do, in many ways, support the argument that the sector entered 2026 on a firm footing.
What the data tells us about the underlying picture
UK Finance recorded just under 60,000 new buy-to-let loans in Q4 2025, representing strong year-on-year growth both in volume and value, with much of that activity driven by remortgage business rather than new purchases.
At the same time, rental yields continued to edge upwards, while average interest rates on new lending fell modestly compared with both the previous quarter and the same period a year earlier, helping to support improved interest cover ratios across landlord portfolios.
There are also signs of stability in terms of loan performance, with arrears falling slightly on the quarter, even though possessions have risen on an annual basis, which reflects a more mixed but still manageable credit environment overall.
Taken together, this data suggests that, as we moved out of 2025 and into the early part of this year, the buy-to-let sector was not only active but functioning in a relatively balanced way, with landlords continuing to refinance, restructure, and, where appropriate, expand.
A market that changed quickly, but not completely
Of course, as we moved into March, the market experienced a period of significant disruption, driven by wider economic uncertainty and sharp movements in swap rates, which in turn led to product withdrawals and repricing across much of the lending landscape.
That had an immediate impact on sentiment, particularly on the purchase side, where some landlords understandably chose to pause while pricing and availability were in flux, and advisers had to work quickly to secure products before they were withdrawn.
However, it would be wrong to view this as a fundamental shift in the health of the sector, because while activity levels may have adjusted in response to those conditions, the underlying drivers of demand have not disappeared.
We are already seeing signs of stabilisation, with lenders, including ourselves, returning to the market with refreshed product ranges and, in some cases, reduced pricing, although it feels far too early to call this as any sense of a return to a pre-March normality.
It would be unwise to assume that conditions will remain stable for any sustained period, particularly given the number of external variables still at play, which means advisers and landlords alike need to remain prepared for further change.
What landlord behaviour is telling us
Looking beyond the short-term movements, our own data over the past 12 months provides a useful insight into how landlord behaviour is evolving in practice.
We have seen an 8.4% year-on-year increase in applications for houses in multiple occupation (HMOs), which points to continued interest in higher-yielding property types, particularly among more experienced investors who are comfortable managing more complex assets. That is supported by the fact landlords with four or more properties now account for 65% of our business, representing a 12% increase over the same period, which underlines the growing dominance of portfolio landlords within the sector.
Perhaps most strikingly, we have recorded a 506% year-on-year increase in applications for tracker products, reflecting a clear shift in how some landlords are approaching interest rate risk, with a preference for flexibility and the ability to benefit from any future rate reductions.
This combination of trends suggests landlords are not stepping away from the market, but they are becoming more selective, more strategic, and more focused on managing both income and financing costs in a way that supports long-term portfolio performance.
A cautious confidence for the months ahead
For advisers, the key message is that confidence in the sector remains justified, but it needs to be tempered with an understanding of how landlord priorities are shifting, particularly when it comes to new acquisitions.
There is little doubt that some investors are taking a more measured approach to purchases in the current environment, waiting for greater clarity on pricing and market direction before committing, but that does not mean the appetite to grow portfolios has disappeared. Instead, it points to a more disciplined approach, where opportunities are assessed carefully and only pursued when the numbers work in a way that aligns with the landlord’s wider strategy.
In the meantime, remortgage activity continues to dominate, providing advisers with a steady flow of business and an opportunity to deliver real value through portfolio reviews, restructuring, and product selection.
Trying to call the direction of the market in the current climate remains difficult, particularly when conditions can change quickly, but by focusing on both the data and the behaviour of landlords, it is possible to build a more grounded view of where the sector stands and where it may be heading next.
