Under Construction Property Home Loan: What Tamil Nadu Buyers Must Know Before Signing
You found a great apartment project in Coimbatore or Tiruppur. The builder's price is right, the location works, and your bank has pre-approved a loan. But the project won't be ready for 18 months. What you're stepping into is an under construction property home loan — and it behaves very differently from a regular home purchase loan.
Most buyers figure this out only when their first EMI statement arrives and looks nothing like what they calculated. Let me break down exactly what to expect.
How Disbursement Works on Under Construction Home Loans
With a ready-to-move property, the bank releases the entire loan amount on registration day. With an under construction property home loan, the bank disburses in tranches — linked to construction milestones set by the builder.
Typical stages: foundation completion, slab work, brick-and-mortar, plastering, and possession. Each stage triggers a partial release. So if your loan is ₹50 lakhs, you might get ₹8 lakhs at stage one, ₹12 lakhs at stage two, and so on.
Here's what most applicants miss: interest starts accruing the moment each tranche is released — not when you take possession. This is where pre-EMI comes in.
Pre-EMI vs Full EMI — Know the Difference
During the construction period, most banks collect only the interest on the amount disbursed so far. This is called pre-EMI or PEMI. Your actual EMI (principal + interest) begins only after full disbursement or possession, whichever comes first.
Say ₹20 lakhs has been released so far at 8.75% per annum. Your monthly pre-EMI interest is roughly ₹14,583. You're paying this every month without reducing principal by even a rupee. Over 18 months, that's nearly ₹2.6 lakhs paid out — and your loan balance hasn't moved.
Some lenders offer a full EMI option from day one, where principal repayment begins immediately. It costs more upfront but reduces total interest outgo significantly. Use our EMI calculator to model both scenarios before you decide.
Tax Benefits and the Under Construction Trap
Many buyers assume they can claim Section 80C and Section 24(b) deductions while the property is under construction. They cannot — at least not yet.
Tax benefits on an under construction property home loan kick in only from the year of possession. Once you get possession, the entire pre-construction interest (the pre-EMI amounts you paid) can be claimed in five equal instalments over five years under Section 24(b), subject to the ₹2 lakh annual cap for self-occupied property.
This is a genuine financial planning point. If possession is delayed — which happens frequently in Tamil Nadu projects — your tax deduction timeline shifts too. The National Housing Bank publishes guidelines on lender obligations when projects are delayed, which is worth reading if your builder's track record is unclear.
What to Check Before Taking This Loan
Project approvals matter more here than with ready properties. Confirm the builder has RERA registration (Tamil Nadu TNRERA), a clear title, and that your lender has already approved the project — not just your profile.
Also check the loan agreement for a clause on what happens if construction is delayed. Some banks have a maximum disbursement window of 24–36 months. Beyond that, terms can change. Our loan document checklist covers what you need for under construction purchases specifically.

Frequently Asked Questions
Can I switch from pre-EMI to full EMI midway through construction?
Yes, most banks — including SBI, HDFC, and ICICI — allow this switch. You'll need to submit a written request. It's worth doing early if your cash flow allows, since it reduces your total interest burden considerably.
What if the builder delays possession beyond the agreed date?
Your bank continues charging pre-EMI interest regardless of builder delays. You can file a complaint with TNRERA for compensation from the builder, but your loan obligation doesn't pause. This is exactly why builder track record matters before you sign.
Is the interest rate higher for under construction property loans?
No — the rate is typically the same as a ready property home loan from the same lender. What differs is the disbursement structure and the pre-EMI period. Check our home loan eligibility checker to see what rate you'd qualify for based on your income and credit profile.
