Five years in buy-to-let: What I’ve learned from a market that never stands still

Originally published by The Intermediary

Just over five years ago, I joined Fleet Mortgages and began what has turned out to be the most fascinating period of my career in financial services. It also marked ten years working in mortgages and twenty-one years in financial services overall, which perhaps explains why milestone anniversaries tend to make you stop and reflect, especially when they come all at once.

When I joined Fleet in 2021, I could not have imagined quite how much would happen over the following five years. Looking back, it feels as though the buy-to-let sector has experienced several different market cycles compressed into a relatively short space of time.

The temptation with articles like this is to focus on statistics, lending volumes, rates or product numbers. All of those things matter, but what has struck me most over the past five years is the sheer pace of change and the resilience shown by everyone involved in the sector, from landlords and advisers and, dare I say it, lenders as well.

From one challenge to the next

When I arrived at Fleet, the market was understandably still dealing with the ongoing shifting nature of the pandemic. Activity levels were strong, borrowing costs were low, and there was a sense that demand for rental property would remain robust for the foreseeable future. My view is that this proved to be correct, although very little else followed the script.

The subsequent period brought inflation, a cost-of-living crisis, rapid increases in Bank Base Rate and the market disruption that followed the ‘Mini Budget’. Anyone working in mortgages during that period will remember days when products were withdrawn, repriced or relaunched at a pace few had experienced before. That has, unfortunately, become a much more commonplace element of the overall mortgage market.

For advisers, it means having difficult conversations with clients whose expectations may have been formed in a very different interest rate environment. For landlords, it often means revisiting investment plans, refinancing strategies and portfolio ambitions. For lenders, it requires constant adaptation to rapidly changing funding costs and market conditions.

What I have learnt throughout this period is that flexibility is not simply helpful in this sector, it is essential.

The continued rise of the professional landlord

One of the biggest ongoing shifts I have observed has been the continued move towards a more professional landlord base. For years we heard predictions of a landlord exodus, and while some landlords have certainly chosen to reduce or exit portfolios, that has never been the whole story. What I have seen is a market that has increasingly rewarded those willing to take a long-term, strategic approach.

Limited company structures have become far more common. Complex property types such as HMOs and multi-unit blocks have attracted greater interest. Portfolio landlords have continued to seek ways to improve yields and make their investments work harder.

The conversations advisers are having today are often much more sophisticated than those I encountered when I first entered the mortgage industry ten years ago. Tax considerations, portfolio management, refinancing options and long-term investment planning all play a much greater role than they once did. That evolution has helped strengthen the sector rather than weaken it.

The importance of advice

If there is one theme that has stood out above all others, it is the value of professional advice. The past five years have demonstrated buy-to-let is not a sector where one solution fits every borrower. Changing affordability calculations, shifting lender criteria, tax changes, product innovation and ongoing regulatory developments have all increased the importance of specialist guidance.

The advisers who have thrived during this period are those who have helped clients look beyond the headline rate and focus on broader objectives. That might mean selecting a tracker product to maintain flexibility during uncertain periods such as now. It might mean restructuring borrowing arrangements. It might mean helping a landlord understand how future regulation could affect their plans. Whatever the situation, advice has become more important, not less.

Resilience remains the defining characteristic

It would be impossible to reflect on the past five years without mentioning the number of times the sector has been written off. Whether it was tax changes, interest rate rises, affordability pressures or regulatory reform, there has been no shortage of predictions that buy-to-let was facing an existential threat. Yet the market remains here, adapting as it always has.

The reason is simple. The UK continues to face a significant shortage of rental housing while demand for privately rented accommodation remains strong. Those fundamentals have helped support the sector through a period of enormous change.

That does not mean challenges have disappeared. Far from it. Landlords continue to face increased costs and greater regulatory obligations, while advisers and lenders must remain alert to changing market conditions. However, resilience has become one of the defining features of the buy-to-let market.

Looking ahead

Predicting the next five years feels like a dangerous exercise given everything that has happened during the last five. If there is one lesson I have taken from my time at Fleet, it is that certainty is often in short supply. Even during 2026 alone, market expectations around interest rates have shifted multiple times as geopolitical events, inflation data and economic forecasts have evolved.

What I do feel confident about is that the sector will continue to adapt. Landlords will continue to seek opportunities. Advisers will continue to help clients navigate increasingly complex decisions. Lenders will continue to develop products and criteria that reflect changing borrower needs.

Five years ago, I joined Fleet expecting to learn about specialist buy-to-let lending. What I have actually learned is how adaptable, innovative and resilient this sector can be when faced with change. Given everything the last five years have thrown at us, that may be the most important lesson of all.
