Fairview will invest 20% of the equity in each of the apartments for up to 25 years under its Easy to Buy scheme.
An earnings threshold has been agreed and people already living in the boroughs of Greenwich, Lewisham, Southwark, Bexley and Bromley will be prioritised.
Fairview New Homes Sales Director Steven Allenby said: Our vision for Victoria Way was to create a desirable address where people could afford to live.
The design process was firmly focused on affordability and quality. Now the buildings are in place we are watching this vision take shape.
The criteria we have put in place represent our commitment to building the homes people in Charlton need at a level they can afford.
With only 31 units available, we are expecting them to sell quickly. Anyone who hesitates will inevitably be left disappointed.
Prices for the apartments will be confirmed in the coming weeks.
Buyers will need a 5% deposit and a 75% mortgage. Fairview New Homes will invest the remaining 20%.
Fairview will not charge interest on its share of the equity. Buyers will simply pay back 20% of the propertys value when they sell, or at any time before if they prefer.
The earnings threshold has been set at £55,000 RPI index linked from 2004. People on the Low Cost Home Ownership Register can also apply.
