Once you've been a tenant for 5 years you may be able to buy your home. The amount of discount you'll get increases depending on how long you've lived in the property. Some property types can't be bought because they are difficult to come by and needed for social housing stock.
The maximum discount available to Housing Executive or housing association tenants applying to buy their home is £24,000. The amount of discount you’ll get depends on how long you’ve lived in the property and how much of the property you’re buying.
