Most property buyers walk into a bank, hear an interest rate of 8.50%, and start negotiating blindly. But here is the brutal, sugar-free truth the banking industry doesn't advertise: that 8.50% is a manufactured number. It is made up of two distinct parts: the non-negotiable base rate set by the RBI, and the highly negotiable "Spread"—the bank's hidden profit margin. If you are applying for a loan without knowing whether you are on the outdated MCLR system or the modern EBLR, or if you can't calculate your bank's exact spread, you are entering the negotiation room blindfolded. Whether you are buying a commercial plot or your dream flat, understanding the 'Spread' is your ultimate weapon. Let’s pull back the curtain on how banks actually price your loan, and give you the exact blueprint to negotiate that margin down and save lakhs of rupees.
