Limited companies have become the majority ownership model for buy-to-let portfolios with 11 to 20 properties, according to new Lendlord data that points to a sharper divide between smaller landlords and more scaled investors.
The latest Q3 2026 figures show 51% of stock in that mid-sized band is now company-held, against 49% in personal names. Across the wider market, private ownership still leads overall at 54.9%, but the crossover point has now moved clearly into view.
That is a useful signal for landlords weighing their next purchase structure. It suggests the shift into company ownership is no longer confined to very large portfolios, even though the financing and tax trade-offs still need careful modelling before any transfer or new acquisition.
Lendlord data shows the company crossover now starts at 11 properties
Lendlord’s Q3 2026 UK BTL Market Report found that 45.1% of buy-to-let ownership is now company-held nationally, with 54.9% still held privately. Among landlords with one to three properties, personal ownership remains dominant at 67.1%.
The balance changes in the 11 to 20 property bracket, where company ownership reaches 51%. Among portfolios with 20 or more properties, the company share rises further to 57.6%.
Aviram Shahar, co-founder and chief executive of Lendlord, said company ownership was “no longer a niche structure used only at the very top of the market” and was already the majority model among larger portfolios.
The report also showed a finance gap between ownership structures, with average buy-to-let mortgage pricing in the same dataset at 4.76% for private landlords and 6.44% for company borrowers. So the move into a limited company structure may suit tax planning or long-term portfolio management, but it does not remove borrowing cost pressure.
This follows Residential Landlord’s reporting on one in five new buy-to-let companies having a non-UK director, which highlighted how company structures were already spreading beyond a narrow specialist niche. The new Lendlord figures add another layer by showing where corporate ownership starts to become the norm by portfolio size.
Residential Landlord has also tracked the wider rise in landlord company registrations, giving this latest dataset a clear place in a longer trend rather than a one-off snapshot.
Ownership structure is becoming an operational choice
The significance of the 11-property crossover is not that there is a legal trigger at that point. It is that portfolios in that range start to behave more like businesses with multiple debt facilities, more tenancies, more record-keeping and less room for sloppy admin.
That matters more now because Making Tax Digital is pulling more landlords into quarterly reporting, while the Renters’ Rights Act is increasing the importance of clean records and process discipline. A structure that worked when a landlord owned three or four properties may become harder to run efficiently once the portfolio doubles or trebles.
Even so, landlords should be wary of treating incorporation as an automatic next step. Stamp duty, capital gains tax, refinancing costs and higher company mortgage rates can all erode the headline tax case if the numbers are weak.

Opinion
The interesting part of this story is not that companies are growing in buy-to-let – that has been clear for years. It is that the crossover point now appears much earlier in the portfolio journey than many smaller landlords may assume. The danger is that some investors will read this as a signal to incorporate first and ask hard questions later.
