The Haryana government has proposed higher collector rates for the Gurugram district, marking the second revision for current financial year. The state government currently reviews the collector rates – also known as circle rates – applicable to the region twice a year. Collector rate is the minimum value at which a property is registered at the time of changing hands, and is a major source of revenue for authorities. These rates are administered by state authorities from time to time, and therefore vary from city to city. While the proposed collector rates may affect demand in the district, it may boost the Noida and Greater Noida markets, say property consultants.
