Topland Group is looking to invest £250m this year in supported housing and continue to commit funds to other niche sectors such as residential land, serviced offices and student accommodation.
During 2017, Topland Henley Healthcare Investments, its joint venture with Henley, invested £100m into supported housing.
In the year-ahead, it plans to deploy a further £250m, bringing overall investment in the sector to £600m.
The company's executive chairman and chief executive Sol Zakay said Topland "continued on a positive growth path during 2017".
Looking to the coming year, he added that the company would opportunistically acquire properties such as multi-let offices and industrial across the UK where it sees potential to add value.
It will also invest in other niche real estate sectors such as land plays, residential portfolios, serviced offices and student accommodation.
Last month, the company announced the launch of a new strategic land company with the Generator Group to buy large unconsented parcels of land across the South of England. In partnership with Cole Waterhouse, it is also delivering a £100m, 682-bed student campus in Wembley in time for the 2019/2020 academic year.
Topland is also set to invest in its hotel portfolio. All its 27 directly operated hotels have been packaged under the Hallmark brand and it is now looking to complete a refurbishment programme and add new hotels to the portfolio through acquisitions as well as development.
In addition, the company continues to invest in its lending arm, which issued £300m of new loans in 2017 taking total lending activity over the £1bn mark.
"For 2018 and beyond we will continue to focus on our core areas of expertise, remain open to collaboration with best-in-class partners and trust our entrepreneurial culture to deliver new opportunities in an evolving market," said Zakay.
