The properties will transfer from Purplebricks to Lomond's two Scottish brands - DJ Alexander (operating in Edinburgh, Glasgow and St Andrews) and Stonehouse (in Aberdeen).
The deal was made for an undisclosed sum.
Lomond’s CEO, Ed Phillips, said:
“As a progressive and ambitious business, we remain proactive in identifying new opportunities that enable us to grow at pace and scale.
“Lomond is in the stand-out position of being able to draw together all the expertise, geographical span and financial capability that is necessary to integrate a Scotland-wide portfolio.
“This latest acquisition is the ideal strategic and geographical fit for Lomond. The properties we inherit are in ideal locations, throughout all our key Scottish heartlands.
David Alexander, chief executive of DJ Alexander and who heads up Lomond’s pan-Scotland operations, added:
“This deal not only represents our strong confidence of the Scottish lettings market, It also heralds another major step forward nationally as we accelerate our ambitions to become the number one UK company in this sector.
“We believe there are excellent opportunities across all areas across the UK, and we will continue to grow in the coming years as landlords, property investors, and tenants welcome the growing range of services that Lomond offers, and the quality of delivery we provide.”
