More Landlords Go Full-Time as Portfolio Sizes Grow, Pegasus Finds
A growing number of landlords are now operating their rental businesses full-time, according to new data from Pegasus Insight. The research also shows that average portfolio sizes are increasing, particularly among limited company landlords.
Pegasus Insight reports that the average landlord portfolio has risen to 7.3 properties. Among limited company landlords, the average portfolio size increased from 12.8 properties in Q4 2025 to 15.3 properties in the latest survey.
The proportion of landlords running their rental business full-time has also grown. Pegasus says 21% of landlords now operate full-time, up from 17% at the end of 2025. Around two-thirds of landlord properties are now held within a corporate structure.
The research highlights that refinancing remains a key driver of mortgage demand. Almost four in ten landlords with mortgages expect to refinance in the next year, with this figure rising to 56% among those with four or more buy-to-let loans. Portfolio landlords are almost twice as likely as smaller landlords to be active in the remortgage market.
These trends indicate a shift towards greater professionalism in the private rental sector, with implications for letting agents and inventory clerks as landlord clients increasingly manage larger and more complex portfolios.
