As metro connectivity expands through Phase II projects and sustainable housing gains momentum, 2025 presents a critical decision point for investors and homebuyers. This analysis compares flats, villas, and plots across 12 parameters to guide your investment strategy.
Decoding South Chennai’s 2025 Real Estate Landscape
Infrastructure Catalysts
The operational Poonamallee–Porur metro stretch by December 2025 will reduce travel time between Selaiyur and Chennai’s IT corridors to 35 minutes. This aligns with the state government’s ₹9,800 crore investment in widening GST Road and establishing new industrial clusters near Mappedu.
Price Trends (2024–2025)
- Flats: 2BHK units in Selaiyur average ₹76L–₹1.22Cr (₹5,652–₹7,182/sq.ft)
- Villas: 3BHK configurations in Mappedu command ₹1.25Cr+ with 22% premium over apartment rates
- Plots: Chengalpattu offers entry points at ₹800/sq.ft, while Perungalathur plots hit ₹4,675/sq.ft
Comparative Analysis: Flats vs Villas vs Plots
Cost Structure Breakdown
| Parameter | Flats | Villas | Plots |
|---|---|---|---|
| Entry Price (2BHK/1200 sq.ft) | ₹76L (Selaiyur) | ₹1.25Cr (Mappedu) | ₹9.6L (Chengalpattu) |
| Maintenance (Annual) | ₹1.2–₹2.5/sq.ft | ₹3–₹5/sq.ft | N/A |
| Registration Charges | 7% property value | 11% property value | 5% land value |
