What is home loan balance transfer?
Also called: balance transfer, BT, loan takeover, refinancing
A balance transfer moves your outstanding home loan to another lender that offers a lower interest rate or better terms. The new lender pays off the old one, takes over your property papers and you start paying EMIs to it.
The case for switching rests on the rate gap and how many years are left. Moving ₹45 lakh with 15 years remaining from 8.9% to 7.6% cuts the EMI from about ₹45,375 to ₹41,970. That's close to ₹3,400 a month, or roughly ₹6 lakh over the remaining tenure. The same gap with only four years left is barely worth the paperwork.
Before you switch, ask your current lender for a rate revision. Many borrowers on older loans linked to MCLR or base rate are paying well above what the same bank offers new customers today, and the bank will often reset you to a repo-linked rate for a modest conversion fee. It's one letter and no new mortgage.
If you go ahead, the process runs like a fresh loan: income documents, a credit check, legal and valuation checks on the property. You get a foreclosure letter from the old lender stating the exact outstanding amount, the new lender pays it, and the original title documents are handed over, which you should confirm in writing. RBI rules bar prepayment charges on floating-rate home loans to individuals, so the old lender can't penalise you. The costs are on the new side: processing fee, legal and valuation charges, and in some states stamp duty on the new mortgage document.
Lenders often offer a top-up with the transfer. Take it only if you need it.
A Kolkata borrower with ₹45 lakh outstanding at 8.9% and 15 years left moves to 7.6%. The EMI falls by about ₹3,400; after paying ₹25,000 in processing and legal charges, the saving over the remaining term is still close to ₹6 lakh.
Borrowers switch for a teaser rate and forget that the new lender's spread over repo is what stays. Compare spreads, not the headline rate, and check whether the old bank will match it first.
Questions people ask about home loan balance transfer
Will a balance transfer affect my tax deductions?
No. Interest and principal on the new loan remain eligible under the same sections (now Sections 22 and 123 of the Income-tax Act, 2025) as long as the new loan only repays the old one.
How long does a balance transfer take?
Usually two to four weeks, most of it spent getting the foreclosure letter and the original documents from the old lender.
