More than 400 social homes are to be transferred to another association after a consultation with tenants.
Choice Housing has said it has a £28m investment programme planned for the 429 properties, which had been run by Victoria Housing Estates (VHE).
VHE tenants will move to Choice, with the housing association taking over ownership of the homes, which will then be renovated and refurbished.
However, those who do not wish to move will be given the opportunity to buy their home.
The homes affected include Riverdale in west Belfast, Benson Street in Lisburn and Worcester Avenue in Bangor.
