The UK's private rented sector is undergoing a seismic shift, as property investment becomes increasingly commercialised. A recent report reveals that landlords are now treating their portfolios like full-time businesses, with the average landlord owning 7.3 properties and a growing number adopting corporate ownership structures.
A staggering 21% of landlords describe themselves as full-time or self-employed, up from 17% at the end of 2025, highlighting the sector's dramatic shift towards larger-scale portfolio ownership. This trend is driven by landlords expanding their portfolios and seeking more complex borrowing solutions to fund their investments.
Limited company landlords continue to dominate the market, with an average of 15.3 properties per landlord, and two-thirds (66%) of their portfolios held through a limited company structure.
The report also highlights a growing demand for specialist finance, with nearly 40% of landlords with borrowing expecting to remortgage within the next 12 months – rising to 56% among those with four or more buy-to-let mortgages. This reflects the increasingly commercial nature of the sector, where larger landlords require more sophisticated lending solutions.
The shift towards larger-scale portfolio ownership has significant implications for lenders and policymakers alike. As larger landlords become more established, they will require more complex borrowing solutions and refinancing support – forcing the mortgage market to adapt and respond.
