When you buy an under-construction flat, the bank releases your home loan in stages as the building goes up. Until the whole loan is released, you choose between pre-EMI, which covers only interest on the amount released, and full EMI, which starts repaying the loan at once. Full EMI costs more each month but less overall.
Quick overview
- What it is: two ways to repay a home loan while your flat is still being built.
- Where it applies: any flat bought on a construction-linked payment plan with a bank or housing finance loan.
- Why it matters: the choice changes how much interest you pay over the life of the loan.
How does a home loan for an under-construction property work?
Most new flats in Vellore and Ranipet are sold while under construction, so the bank releases your loan in stages. The bank sanctions the full loan when you book, but pays the builder only as each construction stage is completed. The builder sends a demand letter, you pay your own share, and the bank releases its part. This is called tranche disbursement.
Banks usually check the project before lending on it, and many keep a list of approved projects. If your project is already approved, the loan is often quicker because the bank has checked the land and approvals once for all buyers.
What is pre-EMI?
Pre-EMI is a monthly payment of interest only, on the amount the bank has released so far. It starts small and rises with each release. None of it reduces your loan. Your regular EMI, which repays both interest and principal, begins only when the bank has released the full loan, usually around handover.
What is full EMI?
With full EMI, you pay the regular EMI from the first disbursement, usually worked out on the full sanctioned loan. Because only part of the loan has been released, most of each payment goes towards principal in the early months. You start repaying the loan straight away and finish sooner.
How do pre-EMI and full EMI compare?
| Pre-EMI | Full EMI | |
| What you pay during construction | Interest on the amount released so far | The regular EMI from the start |
| Monthly payment early on | Low, rising with each release | Higher, fixed |
| Principal repaid before handover | None | Yes |
| Total interest over the loan | Higher | Lower |
| When the loan ends | Full tenure counted from handover | Earlier |
| If construction is delayed | Interest-only payments continue for longer, and the loan is not reduced | Repayment continues as planned, and the loan keeps reducing |
Should you choose pre-EMI or full EMI?
Full EMI usually costs less overall, because you start repaying the principal from the first month and the loan closes sooner. Pre-EMI costs more in total but keeps payments low while the building goes up, so the right choice depends on your cash flow during construction.
Pre-EMI may suit you if:
- you are paying rent until handover and need to keep monthly outgoings low;
- you expect your income to rise by the time the flat is ready;
- the project has a clear RERA completion date and is progressing on schedule.
Full EMI may suit you if:
- you can afford the full instalment now without stretching your budget;
- you want to pay less interest overall and close the loan sooner;
- you would rather your repayments were not affected if construction takes longer than planned.

Can I switch from pre-EMI to full EMI later?
Usually, yes. Many lenders let you switch or prepay. Floating-rate home loans taken by individuals cannot carry prepayment charges under RBI rules, so extra payments during construction cost nothing more.
What tax benefits apply during construction?
Interest you pay before possession, including pre-EMI, is not deducted in the year you pay it. Under the old tax regime, it is claimed in five equal parts starting from the year construction is completed, within the ₹2 lakh yearly limit for a home you live in. If the flat is not completed within five years from the end of the year you took the loan, that limit falls to ₹30,000. The new tax regime gives no interest deduction for a home you live in.
What documents are required for a home loan for an under-construction property?
- Identity and address proof: PAN, Aadhaar, passport or voter ID.
- Income proof: recent salary slips, Form 16 and bank statements, or two to three years of tax returns if self-employed.
- Property papers: allotment letter, agreement for sale and the builder’s RERA registration details.
- Project approvals: building plan approval and title documents, often supplied by the builder.
- Payment proof: receipts for the amount you have paid from your own savings.
Each instalment on a new flat also carries GST, which our guide to GST on residential property explains. If you are looking at Windchimes Apartments in Ranipet, which offers stage-wise payment plans, ask the team about home loan options for the project.
Key takeaways
Pre-EMI keeps early payments low but adds interest that does not reduce your loan. Full EMI costs more each month during construction and saves a large sum over the life of the loan.
Frequently asked questions
1. Is pre-EMI a waste of money?
Not always. Pre-EMI pays only interest, so it does not reduce your loan, but it keeps payments low while you may also be paying rent. It makes sense when cash is tight during construction. If you can afford it, paying full EMI or making extra payments towards principal saves interest over the life of the loan.
2. When does pre-EMI end?
Pre-EMI ends when the bank has released the full loan amount, which usually happens around the time the builder hands over the flat. After that, your regular EMI begins. If construction is delayed, the final release is delayed too, so you keep paying pre-EMI for longer. Check the project’s RERA completion date before you book.
3. Will the bank fund the full price of the flat?
No. Under RBI rules, banks can lend up to 90% of the property value for loans up to ₹30 lakh, 80% for loans up to ₹75 lakh and 75% above that. You pay the rest from your own savings, along with stamp duty and registration charges, which are usually not part of the loan.
4. Can I get a home loan if the project is not approved by my bank?
Often, yes, but it can take longer. The bank will check the builder’s title, approvals and RERA registration itself before sanctioning your loan. Choosing a project that your bank has already approved usually makes the process quicker, so ask the builder for a list of approved lenders.
