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

Under-construction vs ready-to-move — total cost over 3 years to possession
Cost ComponentUnder-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.

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.
