Buy under-construction flats in Chennai at pre-completion prices with construction-linked payment plans. RERA registered projects, zero brokerage on Propspedia.
Propspedia lists 329 under-construction flats in Chennai in 2026, priced ₹15L–₹8.8 Cr — averaging ₹11,702/sqft. Buying under construction means entering ahead of ready-possession pricing and paying on a construction-linked schedule rather than the full amount upfront, in exchange for a wait of typically 1–3 years and 5% GST on the purchase (1% for qualifying affordable housing) that a completed flat with an Occupancy Certificate does not attract. Under-construction supply in Chennai is concentrated in Madhavaram, Anna Nagar, Sholinganallur, Velachery, Kelambakkam. The single non-negotiable check: buy only TNRERA-registered projects — registration obliges the builder to hold 70% of collections in escrow, publish quarterly construction photo updates, and pay 10.5% annual interest on any delay past the committed date. Verify the registration number at tnrera.in before paying a booking amount.

Yes, if the project is TNRERA-registered. Registration obliges the builder to hold 70% of collections in escrow, publish quarterly construction updates with photos, and pay 10.5% annual interest for delays past the committed date. Never book an under-construction flat without verifying the registration number at tnrera.in.
Yes — 5% GST applies (1% for qualifying affordable housing: carpet area up to 60 sqm and a price up to ₹45 lakh). GST is nil once the builder receives the Occupancy Certificate, which is why ready-to-move flats are cheaper net of tax than the headline price alone suggests.
Common plans: Construction-Linked Plan (CLP, payments tied to physical milestones — the safest and TNRERA-recommended), Down Payment Plan (most upfront for a discount), and Possession-Linked Plan (balance on handover). Avoid any plan that front-loads payments ahead of matching construction progress.
