How it differs from a ready property loan
| Ready to move | Under construction | |
|---|---|---|
| Disbursement | Usually one payment | Tranches against progress |
| What you pay during the build | Not applicable | Interest on the disbursed amount |
| When full EMI starts | Immediately | After final disbursement |
| Lender's technical check | Valuation of a finished asset | Project appraisal, repeated at each stage |
| Main risk to you | Price | A gap between demand and release |
How tranche disbursement works
Sanction
The lender approves the full amount based on your income and the project's appraisal. Sanction is not disbursement.
The developer raises a demand
A demand letter stating that a stage has been reached and an amount is due.
The lender verifies
A technical valuer confirms the stage has actually been reached. This is the step that protects you as much as the lender.
The tranche is released
Usually directly to the developer, against the demand.
Your interest obligation rises
You now pay interest on a larger disbursed balance, and the cycle repeats until the loan is fully drawn.
The verification step is worth appreciating. A lender refusing to release because the stage has not been reached is doing you a favour, even when it is inconvenient.
Pre EMI, and what it actually costs
During construction you typically pay interest only on what has been disbursed. It is small at the start and grows with each tranche.
Three years of pre EMI leaves your principal exactly where it started. The money serviced the interest and bought no equity. That is not a trick, it is what interest only means, but buyers routinely think of those years as having made progress on the loan.
Two things follow:
- The real cost of waiting is pre EMI plus rent, for every month until possession. That total is the right number to compare against the price difference of a ready to move alternative.
- Paying full EMI early, where permitted, reduces total interest but raises monthly outflow during the period you are probably also paying rent. Ask your lender whether you may, and model both.
The gap nobody plans for
This is the single most useful paragraph in the article.
The developer's payment plan says what is due and when. The lender's policy says what will be released and when. These are set by two different parties with different interests, and they do not have to agree.
Where the demand runs ahead of the release, the difference is funded by you, from your own money, at that moment. It is not negotiable at that point because you have already booked.
So do this before booking, not after:
- Get the payment schedule in writing, with amounts, triggers and expected dates.
- Take that document, not a summary, to your lender.
- Ask for their disbursement position against it, stage by stage.
- Compute the gap in rupees, and decide whether you can carry it.
This matters most under a front loaded structure. A 50:50 plan asks for roughly half early, which can sit well ahead of what a lender will release against early stage construction.
Want the payment schedule to take to your lender?
The project team can provide the full schedule with amounts and triggers, plus the RERA registration and approvals your lender will ask for.
The paperwork
Beyond the usual identity, income and banking documents, an under construction purchase adds a project layer:
- Agreement for sale, and the allotment letter.
- The developer's demand letters, as each stage is reached.
- The approved plan and the project approvals.
- The RERA registration for your specific phase.
- Title documents for the land, and an encumbrance certificate. What an EC shows is worth understanding before you read one.
- Receipts for every payment made so far, including your own contribution.
Lenders also run their own legal and technical appraisal. Treat a lender's approval of a project as a useful independent signal and a refusal as a question worth pursuing, without treating either as a substitute for your own lawyer.
What to settle before you book
- What will you disburse against this specific payment schedule, stage by stage?
- What is the gap between the developer's demands and your releases, in rupees?
- Do I pay pre EMI or may I pay full EMI during construction?
- What is the total interest I will pay before possession under each option?
- Is the loan at a fixed or floating rate, and what resets it?
- What are the prepayment and foreclosure terms?
- Is this project already approved by you, and if not, how long does appraisal take?
- What is not funded: stamp duty, registration, interiors, deposits?
Question eight sets your own funds requirement, and it combines with everything else that sits outside the base price.
This explains how the mechanism works. It is not financial, tax or legal advice, rates and rules change, and your position depends on your own circumstances. Confirm the figures with your chartered accountant and have a property lawyer read your agreement.
How does a home loan work for an under construction flat?
The lender sanctions the full loan but disburses it in stages as construction progresses, releasing each tranche after verifying the stage has been reached and after the developer raises a demand. You pay interest on the amount disbursed so far until the loan is fully released, at which point full EMI begins.
What is pre EMI?
Interest payable on the portion of the loan disbursed so far, during the construction period, before full EMI starts. It services the interest but does not reduce the principal, so paying pre EMI for three years leaves your loan outstanding unchanged. Some borrowers choose to pay full EMI from the start instead, where the lender allows it.
Will the bank disburse against any payment plan?
Not necessarily. Lenders release against verified construction progress, so a plan demanding a large share early can run ahead of what the lender will release at that stage. This is the most common and most expensive surprise in under construction purchases. Take your actual payment schedule to your lender and get their position in writing before you commit.
Is it better to pay pre EMI or full EMI during construction?
Paying full EMI early starts reducing principal sooner and lowers total interest over the life of the loan, but it raises your monthly outflow during a period when you may also be paying rent. Pre EMI keeps the monthly figure low and costs more in total. The right answer depends on your cash flow rather than on a general rule.
What documents does a lender want for an under construction purchase?
Beyond the usual identity, income and bank records, expect the agreement for sale, the developer's demand letters, the approved plan, the RERA registration for the phase, the title documents for the land, and the developer's own approvals. Lenders also run their own legal and technical appraisal of the project, which is a useful second opinion for you.
Does a lender approving a project mean it is safe?
It means the lender's legal and technical teams were satisfied enough to lend against it, which is meaningful but not a guarantee. It is an independent check on the paperwork, worth having alongside your own. It does not replace your own lawyer or your own reading of the RERA filings.
