The home loan on an under-construction flat: tripartite, disbursement, pre-EMI

A home loan on a finished flat is a single event: the bank pays, you own, the EMI starts. A home loan on a flat that does not exist yet is a process that runs for years, pays out in pieces against a building that may or may not be rising on schedule, and asks you to service money you have not yet lived in. Most first-time buyers price the interest rate carefully and the mechanics not at all, which is the wrong way round, because the mechanics are what surprise them.

What you need before the file opens#

Beyond the obvious income documents, three things about the property decide how smoothly this goes.

A project the lender already knows. Most banks maintain approved-project lists. A flat in an already-appraised project moves in days; one in an unappraised project means the lender does its own legal and technical appraisal first, which is slower and occasionally ends in a refusal that tells you something useful.

A clean title chain and approvals. The lender's lawyer will read what the twelve documents to check describe. Their objection is your objection, arriving free.

Your own cash, quantified honestly. The bank lends against the agreement value. Stamp duty, registration and GST are not part of that base, and they fall due within the same weeks. Buyers who budget the down payment and forget these arrive short at exactly the wrong moment.

The sequence#

The part that surprises people: your loan moves at the building's pace#

Because disbursement is tied to construction stages, the loan is only as fast as the project. If the promoter stops building, the bank stops paying, which sounds protective and mostly is. The complication is that your obligations do not stop with it: interest continues on everything already disbursed, and if you are renting elsewhere, you are paying for two homes while living in one.

This is the reason a lender's approval is not the same thing as a safe purchase, and the reason the promoter's record belongs in your decision rather than only in theirs. A bank appraises title, valuation and your income. It does not usually tell you that the promoter's last three projects ran nine months late, though that is filed, public and directly predictive of how long you will be paying pre-EMI. How to check a builder's track record is the half of the appraisal nobody does for you.

How much the bank will actually lend#

The ceiling is not set by your income alone. RBI caps the loan-to-value ratio by the size of the property, and those caps decide the minimum cash you must bring regardless of how comfortably you could service a larger loan.

Two qualifications matter more than the table. These are ceilings, not entitlements: a lender assessing your income may offer less, and many routinely do. And the LTV is applied to the property value the bank's own valuer arrives at, not to the price you agreed. Where a valuation comes in below the agreement value, the shortfall is yours in cash, on top of the margin, and it arrives as a surprise late in the process.

Then add what sits outside the base entirely. On a Rs 90 lakh Pune flat, the 20 percent margin is Rs 18 lakh, stamp duty and registration run to roughly Rs 6.6 lakh, and GST on an under-construction purchase adds about Rs 4.5 lakh. That is roughly Rs 29 lakh of your own money against a flat most people would describe as a Rs 90 lakh purchase financed at 80 percent. None of it appears in the city affordability figures quoted in the press, which measure the EMI alone; how to read the affordability index sets out what that ratio leaves out.

Pre-EMI or full EMI#

The choice is narrower than it is made to sound, and it is really a cash-flow question rather than a clever one.

Pre-EMI charges interest on the disbursed portion only. It is the smaller number, it rises as more is disbursed, and it repays no principal at all, so at possession you owe exactly what you borrowed. It suits a buyer paying rent at the same time, which is most first-time buyers.

Full EMI starts principal repayment immediately on the sanctioned or disbursed amount, depending on the lender. It costs more each month during construction and less over the life of the loan, because principal starts falling years earlier.

The rule of thumb worth carrying: pre-EMI buys cash flow and costs total interest; full EMI does the reverse. If you are not paying rent, or the construction period is long, full EMI is usually the better trade. If a delay would strain you, the smaller number is worth its cost, and delays in this market are common enough that the rights you get when possession slips are worth reading before you commit to the tighter option.

What the choice is actually worth on a Rs 60 lakh loan, and the maturity date that explains most of the gap usually quoted between the two, is worked through month by month in pre-EMI or full EMI: pricing the construction years.

Priya and Arjun run the numbers#

Priya and Arjun (illustrative, as our stories always are) sanctioned Rs 60 lakh against a Pune flat promised in 30 months, and budgeted around the EMI their bank quoted. Two things they had not modelled arrived first.

The stamp duty, registration and GST were payable within weeks of the agreement and were not part of what the bank funded, so their savings took a hit months before the flat did anything. And their pre-EMI, small and comfortable at the first disbursement, roughly tripled over the following year as more of the loan was released, while they were still paying rent in Kothrud.

Nothing went wrong. The project delivered close to its date and the arithmetic worked. But their own summary afterwards was that they had negotiated hard over about fifteen basis points on the rate and never once asked what the disbursement schedule would do to their monthly outflow, which was the larger number by some distance. The rate earns its attention later, once the loan is running: whether a repo cut ever reaches it depends on the benchmark named in the sanction letter, which is the subject of rate resets and the balance transfer arithmetic.

If you need to walk away mid-construction#

Worth understanding before you need it, because the instinct is wrong. Cancelling the flat does not cancel the loan. They are two contracts: one with the builder for the property, one with the bank for the money. Ending the first leaves the second standing.

What that means in practice is that whatever has already been disbursed remains repayable by you, immediately, and the refund route matters. This is one of the quieter functions of the tripartite agreement: because the lender paid the builder directly rather than paying you, the arrangement generally directs a cancellation refund back to the lender first, to the extent of what was disbursed, with any balance reaching you afterwards. A buyer who negotiates a refund straight into their own account, and spends it, still owes the bank.

Two consequences follow. Read what your own tripartite says about cancellation and substitution before you sign it, rather than at the moment you want out; the terms differ between lenders and they are not boilerplate. And separate the two conversations when the time comes: the builder's deduction is a question under your agreement and, where the fault is theirs, under Section 18, while the bank's position is fixed by what it has already paid out. Conflating them is how buyers end up conceding on both.

The checklist before you sign#

• Read the sanction letter's conditions, not just its rate and amount.
• Ask which stages trigger disbursement and get the schedule in writing.
• Add stamp duty, registration and GST to your cash requirement, and check the dates: the money timeline puts them in order.
• Decide pre-EMI or full EMI on your rent position, not on the smaller number.
• If a subvention scheme is offered, confirm in writing who the borrower of record is.
• Read the promoter's delivery history before accepting a long construction period, because you are financing it.

What the bank's file does not contain#

A lender checks whether the property is good security for a loan. That is a narrower question than whether it is a good purchase, and the gap between the two is where buyers get hurt. ReraGenie's Rs 499 buyer report covers the part the appraisal skips for a Maharashtra project: the promoter's other registrations with the slip between original and current completion dates, this project's own extension history with the reasons the promoter filed, and its complaints and litigation with case numbers. If a long disbursement schedule is what you are signing up for, read the project's free page first and see how the last one went.

The one-line summary#

The sanction is a ceiling, the disbursement is the money, the building sets the pace, and the taxes are yours in cash: price the mechanics as carefully as the rate, because the mechanics are what decide how the next three years feel.
