The property management and finance platform's UK BTL Market Report found that 54.9% of buy to let ownership remains privately held.
Ownership structures vary significantly according to portfolio size. Among landlords with one to three properties, 67.1% of ownership is private, while company ownership becomes the larger share among those with between 11 and 20 properties.
For landlords with portfolios of 20 or more properties, 57.6% of ownership is held through a company.
There are also regional differences. The North East has the highest proportion of company ownership at 53.5%, while company structures also account for the larger share of ownership in Yorkshire and Humberside and Scotland.
Aviram Shahar, co founder and CEO of Lendlord, said: "Company ownership is no longer a niche structure used only at the very top of the market. 45.1% of BTL ownership is already sitting in a company, and among larger portfolios it is the majority model at 57.6%."
"That split matters. Smaller landlords still tend to hold in their own name. Larger landlords, and more of the North, have already moved into companies. Lendlord is the place for landlords to bring portfolio, mortgage and tax data together, stay on top of compliance and manage that shift with confidence."
