Under-Construction vs Ready-to-Move Property: A Full Financial Comparison
Every property buyer faces this question: take the under-construction flat at ₹75 lakh (delivery in 3 years) or the ready flat in the same complex at ₹95 lakh? The under-construction option looks cheaper by ₹20 lakh on paper. But by the time you factor in 3 years of double payments (EMI + rent), GST, and the very real risk of delays, the true gap narrows — sometimes reverses.
The True Cost Comparison
| Cost Component | Under-Construction (₹75L) | Ready-to-Move (₹95L) |
|---|---|---|
| Agreement value | ₹75,00,000 | ₹95,00,000 |
| GST (5% on UC, 0% on RTM) | ₹3,75,000 | ₹0 |
| Stamp duty + registration (~7%) | ₹5,25,000 | ₹6,65,000 |
| EMI paid before possession (if loan from Day 1) | ₹54,000/mo × 36mo = ₹19,44,000 | ₹0 (move in immediately) |
| Rent paid during wait (₹20,000/mo × 36mo) | ₹7,20,000 | ₹0 |
| Total outflow (3-year horizon) | ₹1,10,64,000 | ₹1,01,65,000 |
The under-construction flat costs ₹8.99 lakh more over the 3-year window — despite being ₹20 lakh cheaper on the agreement. The EMI + rent double-payment for 3 years is the killer. If possession is delayed by even 12 months (common), add another ₹4–5 lakh to the UC column.
When Under-Construction Makes Sense Financially
- You currently live rent-free (parents' home) — the double-payment problem disappears
- The builder is top-tier (Godrej, Prestige, Sobha, Lodha) with a strong on-time delivery track record
- The project has RERA registration and the bank is disbursing directly to the builder (not to you)
- The location has high appreciation potential — locking in at today's price for a 3-year later delivery can be genuinely valuable in growth corridors
- You're buying as an investment — the pre-launch discount and appreciation over construction period can be significant for investors not affected by the rent-and-EMI double burden
RERA — The Consumer Protection You Must Use
Under-construction buyers are protected by RERA (Real Estate Regulatory Authority). Key rights:
- Builder must deposit 70% of received funds in a project-specific escrow account
- If possession is delayed, you're entitled to interest (SBI MCLR + 2%) on every EMI paid
- Check the project's RERA registration number on your state's RERA portal before booking
- File complaints at rera.maharashtra.gov.in, karnataka-rera.com, or your state equivalent
Ready-to-Move Advantages Beyond Cost
- What you see is what you get — no specification changes, no quality surprises
- Zero GST (saving 5% on agreement value)
- Immediate possession — no rent + EMI double-burden
- Can negotiate hard on price for old inventory in completed projects
- Home loan available immediately on full disbursement (UC loans involve phased disbursement — some lenders charge pre-EMI interest in the interim)
FAQ
Is there GST on ready-to-move flats?
No. GST applies only to under-construction properties (5% for regular, 1% for affordable under ₹45 lakh). Once the builder receives a completion certificate from the local authority, the property is "ready-to-move" and all subsequent sales are GST-exempt.
Can I get a home loan for under-construction property?
Yes. Home loans are available for UC properties. The bank disburses in tranches linked to construction milestones. You pay "pre-EMI" (interest only on disbursed amount) until full disbursement, then regular EMI. Total interest burden is higher than a RTM loan for the same tenure.
What is the possession delay risk in India?
ANAROCK Research data shows that across India's top 7 cities, over 40% of under-construction projects have delays exceeding 12 months. Tier-1 developers have better records (15–20% delay rate), but even they face delays due to regulatory, environmental, or demand-related reasons.
