A report to Scottish Borders Council has outlined how a potential investment of £163m could create nearly 1,200 affordable homes in the region.
The Strategic Housing Investment Plan sets out projects expected to be delivered between 2017 and 2022.
Between £8.6m and £15m per year could be available for such schemes from the Scottish government.
Combined with other funding and private sector borrowing that could translate to hundreds of new homes.
Between 2012 and 2016, there were 467 affordable homes developed in the region.
However, the latest report said that rate of construction could be stepped up significantly in the years to come.
It said that the first two years of the new programme alone could see a total of 449 affordable homes built across the Borders, in places including Kelso, Lilliesleaf, Duns, Eyemouth and Oxton.
