Delhi stamp duty at a glance
Charged on whichever is higher — circle rate or sale consideration. Women buyers pay 4%, men 6%, joint (male + female) 5%, plus a flat 1% registration fee.
Connectivity & Location
Sector 18 connects via Rohini Sector 18-19 Metro (Yellow Line) with road access on Badli Railway Station Road; Sector 21 leans on Rithala (Red Line) and Sector 21 Main Avenue. Neither is isolated, but one will always be closer to your regular route — measure both against your actual commute before weighing the 129% rate gap.

What the Colony Category Difference Means
Delhi classifies colonies A through H by civic infrastructure and planning age, and these two sectors sit in different bands: Sector 18 is Category D, Sector 21 is Category E. That single letter sets the circle rate and therefore the minimum stamp duty and registration payable — the cheaper category is not a discount on the property, it is a lower government-assessed floor.
Sector 18 vs Sector 21 — Frequently Asked Questions
What is the circle rate difference between Rohini Sector 18 and Sector 21?
Sector 18 has a base residential circle rate of ₹1,28,000/m² (Category D); Sector 21 is ₹56,000/m² (Category E). The gap between them is 129%, with Sector 21 carrying the lower rate.
Which is cheaper to register a plot in — Sector 18 or Sector 21?
Sector 21 is cheaper at the Sub-Registrar, because Delhi stamp duty (6% male, 4% female, 5% joint, plus 1% registration) is charged on whichever is higher: the circle rate or the sale price. On the base circle rate alone, Sector 21 assesses lower per square metre, so the statutory minimum duty is lower there.
How far apart are Rohini Sector 18 and Sector 21?
The two sector centroids are about 2.6 km apart in North West Delhi. Sector 18 lies near Rohini Sector 18 Metro Station, while Sector 21 lies near Sector 21 Central Green — close enough to compare seriously, far enough that daily metro and road access genuinely differ.
How many official DDA layout sheets are available for each sector?
PlotBook has digitized 3 official blueprint sheets for Sector 18 (2 pocket plans) and 10 sheets for Sector 21 (9 pocket plans). Each sheet is the original DDA-published scan, viewable with deep zoom down to individual plot numbers on the sector pages linked below.
Which sector has better metro connectivity?
Sector 18 is served by Rohini Sector 18-19 Metro (Yellow Line); Sector 21 by Rithala (Red Line). If your commute touches the Red Line or Yellow Line differently, one will clearly save time daily — weigh that against the 129% circle-rate gap before deciding.
