- The builder is bound to comply the agreement , and if delayed from the possession date given in the agreement , then builder is bound to compensate the buyer @ 10% .

- As per the RERA Act, if the builder is delaying in construction & delay in possession, then the builder will have to pay 10% interest on the value of the property for delayed possession of flats.
