The short answer
A balance transfer moves your outstanding home loan to a new lender, which pays off the old one and takes over the mortgage. It pays when the interest you save over the remaining tenure is clearly more than the one-time costs of switching: the new lender's processing fee, legal and valuation charges, stamp duty on the new mortgage document where your state charges it, and your time.
The saving is larger when the rate gap is wider, the outstanding balance is bigger and more years remain. A small gap late in the loan rarely justifies a switch. Before moving, ask your current lender to reprice: many will lower your rate, or move you from an old MCLR or base-rate loan to a repo-linked one, for a conversion fee that is often lower than the cost of moving.
Floating-rate home loans to individuals carry no foreclosure charge, so the old lender cannot penalise you for leaving. A top-up loan is extra money a lender gives on top of your existing or transferred home loan, against the same property. It is usually cheaper than a personal loan, but it lengthens your debt and is secured on your home.
Working out whether a transfer pays
You need four numbers: the outstanding principal, the remaining tenure, your current rate and the new rate. Work out the EMI at each rate over the remaining tenure; the difference is your monthly saving. Then add up the switching costs and divide by the monthly saving to get the break-even month.
Worked example (illustrative; assume rates of 9.25 and 8.5 per cent): ₹40 lakh is outstanding with 15 years left. At 9.25 per cent the EMI is about ₹41,168; at 8.5 per cent it is about ₹39,390. The monthly saving is about ₹1,778.
Switching costs (assumed): processing fee of 0.5 per cent of ₹40 lakh, ₹20,000, plus 18 per cent GST, ₹3,600; legal and valuation, ₹10,000; stamp duty on the new mortgage document, ₹15,000. Total about ₹48,600. Break-even: ₹48,600 ÷ ₹1,778 ≈ 27 months. Over the remaining 15 years, assuming both rates stay the same, the net saving is about ₹1,778 × 180 − ₹48,600 ≈ ₹2.7 lakh.
Now take a smaller gap: 9.25 to 9.0 per cent. The EMI falls by only about ₹597 a month. With the same ₹48,600 of costs, break-even takes about 81 months, nearly seven years, and the net saving over 15 years is about ₹59,000 at best. That is the kind of switch that is usually not worth the effort. Our balance transfer calculator does this arithmetic with your numbers.
The calculation assumes both rates stay where they are. With floating rates they will not, and the gap can narrow if the new lender's spread is not lower than the old one's. Compare spreads over the same benchmark, not only today's headline rates.
Ask your own lender first
Many lenders will reprice an existing loan to retain a customer, usually by lowering the spread or by converting a legacy MCLR or base-rate loan to the current external-benchmark rate. They typically charge a conversion fee, which is often lower than the total cost of moving to another lender, and there is no new legal check or mortgage.
Make the request in writing, mention the rate another lender has offered you, and ask for the new rate, the fee and the effective date. Then run the same break-even calculation using the conversion fee as the cost.
If your credit score has improved substantially since the loan started, say so: under the Reserve Bank's external benchmark rules, the credit-risk premium in your spread can change when your credit assessment changes substantially, as your contract provides. Our credit score guide explains this.
How a balance transfer works, step by step
Step 1: get a foreclosure or outstanding statement and a list of documents held from your current lender. Request it in writing; it is needed by the new lender.
Step 2: apply to the new lender with your income documents, the property documents you hold (copies), the old loan's sanction letter and the repayment track record. The new lender does fresh credit, legal and technical checks, as described in our sanction-to-disbursement guide.
Step 3: on sanction, the new lender issues a cheque or transfer for the outstanding amount to the old lender. The old lender closes the loan and returns your original property documents, either to you or directly to the new lender, according to the arrangement. The new lender then creates its mortgage.
Step 4: the old lender must release the original documents and remove its charge from any registry, such as CERSAI, within 30 days of closure, under the Reserve Bank's 2023 directions. If it delays without a reason you accept, it owes you ₹5,000 for each day of delay.
Step 5: check your credit report a month or two later to see the old loan shown as closed and the new one correctly reported.
What the move costs
The new lender's processing fee: a percentage of the loan or a flat amount, often with a cap, plus 18 per cent GST. Lenders sometimes waive or reduce it for transfers; ask.
Legal and technical charges for the new lender's advocate and valuer.
Stamp duty on the new mortgage: in states that charge stamp duty on a memorandum of deposit of title deeds or a mortgage deed, the new lender's mortgage will attract it again. The rate and any cap are set by the state.
Foreclosure on the old loan: none on a floating-rate home loan to an individual. If your old loan is fixed-rate, check the sanction letter or Key Facts Statement for any disclosed charge.
Your time: several weeks of paperwork, and a period during which your original documents are in transit. Insist on a written acknowledgement at each handover.
If the old loan came with a single-premium insurance policy financed into it, find out what happens to that cover after closure, and whether any refund for the unexpired period is due. Our charges and insurance guide explains why.
Top-up loans
A top-up is an additional loan from the lender that already holds your home loan, secured by the same property. Lenders commonly offer it after a period of regular repayment, often alongside a balance transfer. The total of the outstanding home loan and the top-up must stay within the lender's limit on the property's current value.
The rate on a top-up is usually a little higher than on the home loan and lower than on a personal loan. The tenure is often capped at the remaining tenure of the home loan.
Worked example (illustrative; assume 9 per cent): a ₹10 lakh top-up over 10 years has an EMI of about ₹12,668. That EMI counts against your FOIR like any other, and the extra debt is secured on your home.
Use: lenders often ask for the purpose, and some restrict top-ups used for speculative purposes. For tax, what counts is how the money is used: a top-up used to buy, build, repair or renovate a residential house may qualify for the house-property interest deduction within its limits, subject to evidence of use; a top-up used for other purposes does not. Keep bills and a clear money trail, and see our home loan tax benefits guide.
When a transfer is a bad idea
The gap is small, or most of the tenure is gone: most of your remaining EMI is principal, so a lower rate saves little.
The new lender's low rate is a teaser: an introductory rate, or a fixed period, followed by a higher spread. Read the spread and the reset terms.
Your circumstances have changed: a new job on probation, a lower income or a weaker credit report could mean a smaller sanction or a refusal, after you have paid fees.
You are taking a large top-up to fund spending that does not generate income: the cheaper home loan rate does not make the extra debt a good idea.
What to check in the new offer
The benchmark and the spread over it, and whether the spread is fixed for the life of the loan except for a substantial change in your credit assessment.
The reset frequency and the next reset date.
Every fee, in the Key Facts Statement, with GST, and the APR.
Whether the new lender will keep your remaining tenure or lengthen it. A longer tenure lowers the EMI but can wipe out the interest saving.
What happens to any insurance linked to the old loan, and whether the new lender is pushing a new policy (it is optional).
How long the sanction is valid, so that you do not pay fees and then miss the window.
Transferring an under-construction or partly disbursed loan
A loan that is still being disbursed in stages can be transferred, but it is more complicated. The new lender must take over both the outstanding amount and the undisbursed balance, sign a fresh tripartite agreement with the builder, and check the project again. Some lenders will not take over loans on projects they have not approved.
If the project is delayed, the transfer can stall on the builder's paperwork. In that case, ask your current lender to reprice instead, and look at the transfer again after possession.
Do not keep the EMI saving as the only measure. Lowering the EMI while keeping the same end date is one choice; keeping the same EMI and finishing earlier is another, and usually saves more interest. Our prepayment calculator shows the effect of paying more than the minimum.
Common mistakes
Comparing headline rates without adding the switching costs.
Not asking the current lender to reprice first.
Comparing a new lender's rate on a different benchmark from your current one.
Moving for a gap of a fraction of a percentage point late in the tenure.
Letting original documents travel between lenders without written acknowledgements.
Using a top-up for consumption and claiming it as home loan interest for tax.
Common questions
When should I transfer my home loan to another bank?
When the interest saved over the remaining tenure clearly exceeds the switching costs, usually with a meaningful rate gap, a large outstanding balance and many years left. Work out the break-even month first, and ask your lender to reprice before moving.
Is there a foreclosure charge when I transfer my home loan?
Not on a floating-rate home loan to an individual. Fixed-rate loans may carry a charge, which must be disclosed in the sanction letter and Key Facts Statement.
What charges apply on a home loan balance transfer?
The new lender's processing fee with GST, legal and valuation charges, and stamp duty on the new mortgage document in states that charge it. Some lenders reduce fees for transfers.
How long does a balance transfer take?
Usually a few weeks, depending on how quickly the old lender issues the outstanding statement and documents and how fast the new lender completes its checks.
What is a top-up home loan?
An additional loan from your home loan lender against the same property, usually at a rate a little above the home loan rate, with the combined loan kept within the lender's limit on the property's value.
Can I claim tax benefits on a top-up loan?
Only if the money is used for buying, building, repairing or renovating a residential house, within the house-property rules and limits, and you can show the use. Not for other purposes.
