Circle rates are usually defined by the local state government's revenue departments or the local development authorities, in line with what they perceive the prices at which property sale or transfer should be undertaken.
Hi, I think the circle rates are decided by the State Revenue Ministry. It is the minimum rate for the valuation of a plot, flats or independent house in a particular area or locality. The circle rates differ for various categories of colonies. The sale or purchase of property in a particular area is finalized considering the available infrastructure.
