Home Loan Top-Up
A top-up on an existing home loan is usually the cheapest large borrowing available to a salaried Indian outside a loan against fixed deposit — typically priced a little above the base home loan rate and far below the 10–24% of an unsecured personal loan.
Varies by lender and by how much equity you hold.
The constraint is end use: the money cannot go into equity markets or speculative property, and lenders are entitled to ask.

What to know
The comparison people should make and rarely do is against the alternative they were about to use. A ₹10 lakh personal loan at 14% over five years costs roughly ₹3.9 lakh in interest. The same ₹10 lakh as a top-up at 8.5% over the same five years costs about ₹2.3 lakh. The catch is that top-ups are often written over the remaining home loan tenure, so a fifteen-year top-up at 8.5% costs more in total interest than the five-year personal loan even at the lower rate. Match the tenure to the need, not to the parent loan.
Tax treatment follows use, not label. Interest on a top-up used for construction, repair or renovation of the house can qualify under Section 24(b), within the applicable cap. Used for a wedding or a car, it qualifies for nothing. Keep the invoices — the deduction is claimed by you and defended by you.

Questions
How much top-up can I take on my home loan?
Lenders size it against the property value and your repayment record — commonly so that the home loan plus top-up stays within the LTV cap for that ticket size. In practice you need a couple of years of clean repayment history and meaningful equity in the property before a top-up is offered at all.
Can I use a home loan top-up to invest?
No. End-use restrictions explicitly exclude investment in equities and speculative activity, and lenders can ask for evidence of use. Beyond the contractual issue, borrowing against your home to buy equities is a genuinely bad idea: it converts a market drawdown into a housing risk.
Is a top-up better than a loan against property?
Usually yes if you already have the home loan — the property is already mortgaged, so there is no fresh valuation, no new mortgage registration and no second set of legal fees. A loan against property makes sense when you need more than the top-up limit allows, or when you own the property outright.
