Portfolio landlords driving market direction, not small-scale investors

A key takeaway from the latest data is not just what landlords are doing, but who is shaping those decisions. According to the Property118 Landlord Sentiment Survey Q1 2026, the private rented sector is increasingly driven by experienced portfolio landlords rather than small-scale or occasional investors.

Based on 2,380 completed responses covering 23,098 rental properties, the average landlord now owns 9.7 properties. You can review the full findings here.

The implication is clear: decisions made by portfolio landlords are shaping the direction of the market.

A different type of landlord

Public perception often centres on the idea of the small, part-time landlord with one or two properties, but the survey data presents a different reality.

With an average portfolio approaching 10 properties, many landlords operate at a scale that requires structured decision making, long-term planning and a clear understanding of financing and risk. These are not incidental investments, they are established property businesses.

Why scale matters

Portfolio size influences behaviour.

Larger landlords are more likely to:

• take a strategic view of their holdings
• assess long-term market trends
• consider financing structures in detail
• plan for succession and continuity

This is reflected in broader findings from the Property118 dataset, including a tendency towards lower leverage, a focus on simplification and a growing inclination to reduce or rebalance portfolios.

A concentration of influence

When a relatively small group of portfolio landlords controls a large number of properties, their collective decisions carry significant weight.

If such landlords choose to reduce exposure, hold rather than expand or exit entirely, the impact on supply and market activity can be substantial.

This creates a different dynamic from one driven by a large number of smaller investors.

The market becomes more sensitive to the strategic decisions of experienced operators.

Implications for policy and lending

Understanding who drives the market is important for those shaping it. Policy decisions, lending criteria and regulatory frameworks are often designed with a broad landlord base in mind. The data suggests that a significant proportion of the sector operates at a more advanced level. This raises questions about whether current frameworks fully reflect how the market functions in practice.

A sector defined by its decision makers

The survey reinforces a simple point; the future of the private rented sector is not determined solely by external conditions, but by the decisions of those who control the majority of its assets.

When those decision makers are experienced portfolio landlords, their actions set the direction.

For now, one conclusion stands out: the UK rental market is increasingly shaped by portfolio landlords, and their strategic choices are driving its evolution.

A conversation worth having?

If you are weighing up your own strategy, whether that’s to sell, expand, or restructure to improve profitibility, it is worth having a discussion with a Property118 consultant to take a closer look at how your portfolio is structured as a whole now, and to forecast the outcomes based on multiple scenario’s.

These conversations are typically most useful for landlords with established portfolios and relatively modest borrowing who are beginning to reflect on how their assets could work more effectively in the years ahead.
