Key Differences at a Glance
| Factor | Under Construction | Ready to Move |
|---|---|---|
| Price | 15–25% lower | Market price |
| GST | 5% on non-affordable; 1% on affordable | Nil |
| Possession | 2–4 years wait | Immediate |
| Customisation | High | Low |
| Loan EMI | Pre-EMI until OC | Full EMI from day 1 |
| RERA protection | Mandatory | Optional for resale |
When to Choose Under Construction
- You have 2–3 years before you need to move in
- Budget is tight — you want lower entry price
- You want to customise interiors (flooring, kitchen layout)
- The builder has a verified RERA track record
When to Choose Ready to Move
- You need the property within 3–6 months
- You want to avoid GST (saves 5% on ₹1 crore = ₹5 lakh)
- You want to inspect the actual flat, not a sample unit
- You're buying for rental income — ready property earns from day 1
The Hidden Costs of Under Construction
Total extra cost = GST (5%) + Pre-EMI interest + Delay risk
On a ₹80 lakh flat with 3-year construction period:
GST = ₹4 lakh | Pre-EMI interest = ~₹6–8 lakh | Total extra = ₹10–12 lakh
This partially erases the 15–20% price advantage — always calculate total cost of ownership.
