Buying flat in Chennai is one of the most significant financial decisions you’ll ever make.

From understanding hidden costs to verifying legal approvals, every step plays a role in securing a safe and valuable property. Here’s a comprehensive guide to help you make an informed decision before buying a flat in Chennai.
The first step before buying a flat in Chennai is identifying why you are buying it.
For personal use: Focus on comfort, proximity to schools, workplaces, hospitals, and daily conveniences.

Stamp duty and registration charges
Home loan processing fees
