what is the SAC code ,when Renting of own resedential properties for Residential purpose,


earlier I confused that code was 997211,when Searching GST rate against 997211 it shows that 18% that means I understood like 997211 is applicable when rent out own Residential property for commercial purposes


please clarify me
