I'm a teacher in Bangalore and bought my first home last year after 3 years of research. Sharing my checklist for anyone who's just starting out - wish someone had given me this when I began!
The 10 things I verified before signing anything:
1. RERA registration - check Karnataka RERA (rera.karnataka.gov.in). Confirm the project number, the registered completion date, and whether the builder has paid penalties for delays.
2. Encumbrance Certificate (EC) - get this from the sub-registrar office. Shows if there are any pending loans or disputes on the land/property.
3. Khata - for Bangalore specifically, confirm it's BBMP A-Khata (not B-Khata or revenue site). Without A-Khata, home loan and resale both become complicated.
4. Building plan approval - ask the builder for BBMP/BDA sanctioned plan. The plan should match what's actually being built.
5. Land conversion - if it's on converted agricultural land, verify the DC conversion order is complete and final.
6. Builder track record - visit their completed projects, talk to residents. Check RERA for past penalty orders against them.
