ThriftRupee Insight

Under-construction property looks cheaper by 10–20% but the real cost is often higher. A 3-year construction period on a Rs 80 lakh flat at 8.5% home loan means Rs 17 lakh in pre-EMI interest paid before possession — without a single month of full EMI running. Ready-to-move properties cost more upfront but you start living (or renting out) immediately, and the total cash outflow is often lower.

Under-Construction vs Ready Property — True Cost Comparison

Under-construction properties appear cheaper by 10–20%, but the total cash outflow over 3–5 years is often comparable or higher when you account for 5% GST (not applicable on ready-to-move), pre-EMI interest during construction, and the opportunity cost of not living in or renting out the property during the wait. This calculator does all the math for you.

Frequently asked questions

What is pre-EMI in an under-construction property?
Pre-EMI is the interest paid on the loan amount disbursed during the construction period, before full EMI kicks in at possession. As the builder raises construction-linked demands, the bank disburses more, and pre-EMI increases. Full EMI begins only after the final disbursement. Pre-EMI payments do not reduce the principal.
Is ready-to-move property better than under-construction?
Ready-to-move advantages: No GST (resale), immediate possession, no construction risk, no pre-EMI loss, can start renting immediately. Under-construction advantages: lower sticker price, new construction, RERA protection, sometimes GST input credit. Total cost over 3–5 years including pre-EMI interest usually makes ready-to-move comparable or cheaper.
Is GST applicable on under-construction property?
Yes. GST at 5% (affordable housing at 1%) applies to under-construction or newly completed properties (within 1 year of OC). Ready-to-move properties (OC received, not sold within 1 year) are GST-exempt. For a Rs 80 lakh under-construction flat, 5% GST adds Rs 4 lakh to the cost.
