The hidden cost of buying under-construction property \u2014 and how to minimize it.
When you buy an under-construction property, your bank doesn't give the builder the full loan at once. Instead, it releases money in stages — each time the builder completes a construction milestone (booking, foundation, slab, plaster, possession).
Each release is called a disbursement. And from the moment each tranche is disbursed, you start paying interest on it.
This interest-only payment during construction is called pre-EMI interest. Unlike regular EMI, it doesn't reduce your principal — it's pure interest cost. Your full EMI (principal + interest) only starts after complete disbursement, usually at possession.
Let's take a real example. You buy a ₹1 crore apartment with an ₹80 lakh loan at 8.5%. The builder's payment plan:
• Month 1: ₹10L (booking — 12.5%)
• Month 6: ₹10L (foundation — 12.5%)
• Month 12: ₹15L (slab — 18.75%)
• Month 18: ₹15L (brickwork — 18.75%)
• Month 24: ₹15L (plaster — 18.75%)
• Month 30: ₹15L (possession — 18.75%)
Your pre-EMI interest over 30 months: approximately ₹5.2 lakhs. That's money paid to the bank that doesn't reduce your loan by a single rupee.
1. Pay from savings at early milestones: If you pay the first 1-2 milestones from savings instead of taking a loan disbursement, you delay when interest starts accruing. Even ₹10 lakhs paid from savings at booking saves ~₹2.1 lakhs in pre-EMI interest over 30 months.
2. Choose a builder with a later payment plan: A 20-80 scheme (20% during construction, 80% at possession) means the bank disburses 80% only at the end — dramatically less pre-EMI interest compared to a construction-linked plan.
3. Opt for full EMI from start: Some banks allow you to start paying full EMI (principal + interest) from the first disbursement instead of pre-EMI. This means you start reducing principal immediately. You pay more per month during construction but save significantly over the loan's life.
4. Make lump-sum prepayments during construction: If you receive a bonus or have savings, paying it toward the principal during construction reduces the base on which pre-EMI interest is calculated.
This is where most people get stuck. Builder A has a six-milestone plan. Builder B offers 20-80. Same apartment price. Which costs less over 20 years?
The answer depends on the timing of disbursements, your savings capacity, the interest rate, and whether you plan to prepay. A simple EMI calculator can't answer this — you need a tool that models progressive disbursements.
Set up your builder's exact payment plan with multiple disbursement tranches. See how each milestone affects your interest, when your full EMI kicks in, and what happens if you prepay at specific stages.
