Why we made these

Sellers quote kattha and dhur, government records show decimal and acre, builders quote sq ft. Buyers lose money in the gap.
Registry cost went up in June 2026 (7% stamp duty and a higher MVR). Many people still plan with the old 6% + 2%.
Every number here is checked against Bihar Gazette notifications and the same fact-checked figures as our articles.
