A Bengaluru buyer eyeing an 80 lakh flat in 2026 assumed a 10 percent down payment, about 8 lakh, would see her through. The real number was closer to 25 lakh once the loan cap and the stamp duty were counted, and the gap nearly cost her the deal. The single most common budgeting mistake first time buyers make is underestimating the cash they must bring, and it comes down to two things the bank rarely spells out, the loan to value cap and the costs it excludes.

The short answer. The RBI limits how much of a home's value a bank can lend, called the loan to value ratio, and it is banded by price. A bank can lend up to 90 percent for a home costing 30 lakh or less, up to 80 percent for a home between 30 and 75 lakh, and up to 75 percent above 75 lakh. So your minimum down payment is about 10, 20 or 25 percent depending on the price. The catch is that stamp duty and registration are excluded from the loan and from the value used for this cap, so you fund those separately on top of the down payment. The real upfront cash a Bengaluru buyer needs is the down payment plus roughly 6 to 7 percent of the price for duty and charges. Plan for that total, not just the down payment.

This is a buyer-side guide for Bengaluru. It explains the loan to value caps, the true upfront cash, why the extra costs bite, and how to plan the number without a nasty surprise.

What is the loan to value ratio and why does it matter?

The loan to value ratio, or LTV, is simply the share of a property's value a bank is allowed to lend. The RBI caps it so that borrowers always have real equity in their home, which protects both the buyer and the banking system. Because the cap is set by the regulator and banded by price, it directly fixes the minimum down payment you must fund yourself. A buyer cannot borrow the whole price, no matter how strong their income, so the down payment is not negotiable below the regulatory floor.

For a Bengaluru buyer the practical meaning is that the price band of the home you choose determines the minimum cash you need. Cross from just under 75 lakh to just over it, and your minimum down payment steps up from 20 to 25 percent, a jump worth knowing before you fall in love with a flat at the edge of a band.

How much can a bank lend by price band?

The caps are straightforward and banded. For a home costing 30 lakh or less, a bank can lend up to 90 percent of the value, so your down payment can be as low as 10 percent. For a home between 30 and 75 lakh, the cap is 80 percent, meaning at least a 20 percent down payment. For a home above 75 lakh, the cap is 75 percent, so you fund at least 25 percent yourself. These are ceilings, not entitlements, and a bank may lend less based on your income, credit score and the property, so treat the cap as the best case rather than a promise.

Why is your real upfront cash higher than the down payment?

Because the loan to value cap is calculated on the property value alone, and the RBI excludes stamp duty, registration and documentation charges from it. That means the bank will not lend against those costs, and you pay them out of pocket in addition to your down payment. In Karnataka that is roughly 6 to 7 percent of the price for stamp duty and registration, plus the small mortgage registration charge on your loan. There is a narrow exception for very low value homes under about 10 lakh, where lenders may fold these costs into the calculation, but for a typical Bengaluru flat you should assume they sit entirely on you.

So the honest budget is your minimum down payment plus about 6 to 7 percent of the price for duty and charges. On an 80 lakh flat that is roughly 20 lakh down plus around 5 lakh in duty and charges, close to 25 lakh in cash before you own the keys. Planning for the down payment alone is exactly how buyers get caught short at registration.

How should a Bengaluru buyer plan the number?

The way to avoid the trap is to compute the full cash requirement early, in the same breath as your EMI, rather than treating the extra costs as an afterthought.

1. Identify your home's price band to find the maximum LTV and minimum down payment.
2. Assume the bank may lend a little less than the cap, and keep a margin.
3. Add stamp duty and registration, roughly 6 to 7 percent of the price in Karnataka.
4. Add the mortgage registration charge on your loan, about 0.6 percent of the loan.
5. Keep an emergency buffer separate from all of this, not spent on the purchase.
6. Confirm your sanctioned loan and actual LTV in writing before you commit.
7. Fund duty and charges from savings, since they cannot be added to the loan.

Because those excluded costs are a big part of the surprise, plan them precisely with our breakdowns of Karnataka stamp duty and registration and the often forgotten MODT mortgage registration charge. When you size all of this against a specific home, such as Assetz Soho and Sky, run the full cash requirement, not just the down payment, before you decide.

Is a bigger down payment better?

Often, but not always, and it deserves a clear head. Putting down more than the minimum shrinks your loan, your EMI and your total interest, and it can occasionally earn a slightly better rate, so a buyer with surplus savings usually benefits from a larger down payment. But there is a limit to how far to push it. Draining your emergency fund or your investments to make a very large down payment can leave you dangerously illiquid, and since a home loan is among the cheapest debt available with tax benefits attached, it is not always wise to minimise it at all costs. The sensible middle is to comfortably exceed the minimum if you can, while keeping a solid cash buffer intact, rather than emptying every account to borrow as little as possible.

What is the honest limitation of the LTV rule?

The LTV cap tells you the most a bank may lend, but it does not tell you what you can afford, and confusing the two is a real risk. Just because a bank will fund 80 percent of a 75 lakh flat does not mean the resulting EMI fits your life, so run the EMI math and your monthly budget before you let the loan cap set your ceiling. The rule also does not lower the real cash you need, since the excluded duty and charges are unavoidable. Treat the LTV band as a planning input that fixes your minimum down payment, layer the duty and charges on top, and then test the whole thing against an EMI you can genuinely carry. A buyer who plans the full cash requirement and a comfortable EMI, rather than the headline loan amount, is the one who reaches registration without a scramble.

What if the bank values the home below your price?

Here is a subtlety that trips up buyers at the last moment. The loan to value cap is applied to the bank's own assessed value of the property, and lenders generally lend on the lower of your agreed price or their valuation. If the bank values the flat below what you agreed to pay, your loan is calculated on the lower figure, which quietly raises the cash you must bring. On an 80 lakh purchase valued by the bank at 75 lakh, your 75 percent loan is figured on 75 lakh, not 80, so you fund the shortfall as well as your normal down payment. This is why it is worth getting the bank's valuation early, before you are committed, and keeping a small extra reserve in case the valuation comes in light. A buyer who assumes the bank will simply lend against the sticker price can be surprised by a gap of several lakh right when the money is due.

How much down payment do I need for a Bengaluru home loan?

Your minimum down payment depends on the price band. RBI lets banks lend up to 90 percent for a home costing 30 lakh or less, up to 80 percent between 30 and 75 lakh, and up to 75 percent above 75 lakh. So you fund at least about 10, 20 or 25 percent, plus stamp duty and registration.

Are stamp duty and registration included in the loan?

No. The RBI excludes stamp duty, registration and documentation charges from the loan to value calculation, so banks do not lend against them. You pay these out of pocket in addition to your down payment, roughly 6 to 7 percent of the price in Karnataka. Only for very low value homes under about 10 lakh may lenders include such costs.

Can I get a bank to lend the full price of a home?

No. The RBI loan to value caps mean a bank cannot lend the entire price, regardless of your income. The most is 90 percent for a home up to 30 lakh, falling to 75 percent above 75 lakh, and a bank may lend less based on your profile. So a down payment below the regulatory floor is not possible.

Should I make a larger down payment than the minimum?

Usually yes, if you can do it without draining your emergency fund. A bigger down payment lowers your loan, EMI and total interest. But a home loan is cheap debt with tax benefits, so do not empty every account to minimise it. Exceed the minimum comfortably while keeping a solid cash buffer intact for emergencies.
