The UK mortgage market is witnessing a significant shift as company buy-to-let (BTL) ownership has now surpassed private ownership in the 11-20 property bracket, marking a pivotal change in landlord dynamics. This trend is particularly relevant for investors and landlords, as it reflects evolving strategies in property investment.

How Has Company Ownership Changed in the Mortgage Market?

Recent data reveals that company ownership is increasingly prevalent among landlords, especially those managing larger portfolios. For landlords with 20 or more properties, company ownership has risen to 57.6%. In contrast, the proportion of privately held properties has decreased from 67.1% to 42.4%. This shift suggests that many landlords are opting for corporate structures, likely to benefit from tax efficiencies and limited liability.

What Are the Regional Trends in the Mortgage Market?

Regionally, the North East emerges as the UK’s leading corporate BTL market, with 53.5% of ownership through companies. Yorkshire and the Humber closely follows at 53%, while Scotland ranks third. The North West also shows significant corporate ownership at 48%. Conversely, Greater London and Northern Ireland maintain a stronghold on private ownership, with 66.7% and 77.8% respectively.

What This Means for Landlords

Landlords should be aware of the implications of this trend. The average portfolio value for landlords with 1-3 properties is around £417,000, while those with 20 or more properties see values soar to £8.96 million. Additionally, borrowing costs differ significantly, with average mortgage rates at 4.76% for privately owned properties compared to 6.44% for company-owned holdings.
