Home Loan Guide: EMIs, Down Payment, Tax Benefits and Eligibility (India)

A home loan is probably the biggest debt you will ever take on, and also the cheapest large loan available to you. It is secured against the property itself, it comes with a repayment window as long as 30 years, and if you use the old tax regime, the government actively subsidises part of your interest and principal. Get the structure right at the start and it works quietly in the background for decades. Get it wrong, floating vs fixed, wrong tenure, ignoring the tax angle, and you overpay by lakhs without noticing.

This guide walks through exactly how home loans work in India today: what rate you should expect, how much down payment you need, how the EMI is actually built, and how much you can legally claw back through tax benefits if you stay on the old regime. We will run a real ₹50 lakh loan through the numbers so you can see what it means for an actual household.

1. How much of the property will the bank actually finance?

Banks do not lend 100% of the property value. The Loan to Value (LTV) ratio caps how much you can borrow, and it scales down as the property gets more expensive.

Property value	Maximum LTV	Minimum down payment
Up to ₹30 lakh	90%	10%
₹30 lakh to ₹75 lakh	80%	20%
Above ₹75 lakh	75%	25%

Core rule: the down payment is not optional and not negotiable below these floors. Save for it well before you start hunting for a property, because a bank will not bridge that gap for you.

On top of the down payment, budget separately for stamp duty, registration charges, brokerage if applicable, and interior or furnishing costs. These are commonly underestimated and can add up to 8% to 12% of the property value on top of your down payment.

2. What interest rate should you expect?

Home loan rates in India today run roughly from 7.10% to 9.75% per annum, with most borrowers with a decent credit score and stable income actually landing in the 7.65% to 8.50% band. Almost all home loans today are floating rate, linked to an external benchmark (commonly the RBI repo rate), which means your rate moves when the RBI moves.

Your exact rate depends on your CIBIL score, income, loan amount, tenure, and which lender you pick, so it always pays to compare at least 3 lenders before signing. A 0.25% difference in rate on a ₹50 lakh, 20 year loan is not a rounding error, it is real money over the life of the loan.

Core rule: shop your home loan the same way you'd shop for the flat. A slightly lower rate from a competing bank is worth the extra paperwork.

3. Tenure: how long can you stretch it?

Home loans can run up to 30 years, the longest tenure available on any common retail loan in India. A longer tenure lowers your EMI, which is why lenders love advertising 30-year options, but it also means you pay far more total interest, because you are carrying a large principal for a much longer time.

A reasonable approach: take the longest tenure the bank offers to keep your EMI manageable and your monthly cash flow safe, but plan to prepay aggressively once your income rises, rather than committing to a punishing EMI on a shorter tenure from day one.

4. The EMI, worked out on a real ₹50 lakh loan

Say you and your spouse are buying a flat and taking a joint home loan of ₹50,00,000 at 8% per annum for 20 years (240 months).

Using EMI = P × r × (1+r)^n / ((1+r)^n − 1), where r is the monthly rate (8% ÷ 12 ÷ 100 = 0.006667) and n is 240 months, your EMI comes out to approximately ₹41,822 a month.

Over 20 years that is a total repayment of roughly ₹1,00,37,000, against a principal of ₹50,00,000. So you pay back almost exactly double what you borrowed, with the difference, about ₹50,37,000, being interest. That is the real cost of spreading a home loan over two decades, and it is exactly why prepayment and tenure choice matter so much.

Tenure	Approx. EMI	Approx. total interest paid
15 years	₹47,780	₹35,00,000
20 years	₹41,822	₹50,37,000
25 years	₹38,590	₹65,77,000

Cutting 5 years off the tenure (20 to 15) raises your EMI by about ₹5,950 a month, but it saves you over ₹15 lakh in interest over the life of the loan. If your income can support the higher EMI, the shorter tenure almost always wins.

5. Tax benefits: only under the OLD regime

This is the part most borrowers get wrong. Home loan tax benefits exist ONLY if you file under the old tax regime. The new regime (the default since it became the standard option) blocks almost all of these.

Section	What it covers	Limit	Regime
Section 24(b)	Interest paid on the home loan (self-occupied property)	Up to ₹2,00,000 per year	Old regime only
Section 80C	Principal repaid on the home loan	Up to ₹1,50,000 per year (shared with other 80C investments like EPF, PPF, ELSS)	Old regime only
Section 80EE / 80EEA	Additional interest deduction for first-time buyers	Closed for new loans; only claimable if your loan was sanctioned in the old eligible windows	Old regime only

If the property is let out (rented), the Section 24(b) interest deduction is not capped at ₹2 lakh, the entire interest is deductible against rental income, though the loss you can set off against other income in a year is capped at ₹2 lakh, with the balance carried forward.

Core rule: if you have a large home loan, run your tax calculation both ways (old regime with home loan deductions vs new regime without them) before deciding. For most people with a big loan and few other deductions, the old regime wins purely because of Section 24(b) and 80C.

6. Joint home loan: nearly double the tax benefit

If you take the loan jointly, say with your spouse, and both of you are co-owners and co-borrowers, each of you can separately claim your own Section 24(b) interest deduction (up to ₹2 lakh each) and your own Section 80C principal deduction (up to ₹1.5 lakh each), in proportion to your share of the EMI paid.

Continuing the ₹50 lakh joint loan example above: if you and your spouse split the EMI 50/50, and your combined annual interest in year one is roughly ₹3,90,000 with principal of about ₹1,17,000, each of you can claim your own share, up to ₹2 lakh interest and up to ₹1.5 lakh principal, individually. Structured well, a joint loan can let a household claim close to double the deduction of a single-borrower loan, as long as both partners have taxable income to offset it against and both are old-regime filers.

Core rule: a joint home loan is a tax-planning tool, not just a way to qualify for a bigger loan amount. Structure the ownership and EMI split deliberately.

7. Fixed vs floating rate: which should you pick?

Feature	Fixed rate	Floating rate
Rate stability	Locked for a period (or the full tenure, rare)	Moves with the benchmark (repo-linked)
Typical starting rate	Usually higher than floating	Usually lower than fixed at the start
Best when	You expect rates to rise sharply	You expect rates to stay flat or fall
Availability in India	Rare for the full 20 to 30 year term; some lenders offer fixed for an initial window only	The overwhelming majority of Indian home loans today
Prepayment flexibility	Often more restricted	Floating-rate loans usually carry NO prepayment penalty by RBI rule

In India, almost every home loan is floating rate today, and RBI rules mean floating-rate home loans to individual borrowers cannot carry a prepayment or foreclosure penalty. That is a meaningful advantage over fixed-rate loans and over personal loans, where prepayment penalties are common.

Core rule: unless you have a very specific reason to expect rates to spike, floating rate is the practical default in India, and it comes with the added benefit of penalty-free prepayment.

8. Should you prepay your home loan or invest instead?

This is the question every home loan borrower eventually asks. The honest answer depends on your interest rate and your alternative use of the money.

• If your home loan rate is around 8% and you are in the old regime claiming the Section 24(b) and 80C benefits, your effective post-tax cost of borrowing is meaningfully lower than the sticker rate.
• Prepaying reduces a guaranteed, contracted cost. Investing carries market risk. There is no universally correct answer, but a reasonable framework: prepay aggressively in the early years when interest forms most of your EMI, and once the loan is more principal-heavy, evaluate investing surplus cash instead.
• Any home loan prepayment reduces your outstanding principal directly (floating rate, no penalty), which shortens your tenure or lowers your EMI, your choice.

Core rule: prepay lump sums (bonus, increment, maturity proceeds) toward your home loan whenever the money is not already earmarked for your emergency fund or a higher-priority goal. It is a low-risk, guaranteed return equal to your loan's interest rate.

9. Eligibility: what banks actually check

Beyond your down payment, lenders assess:

• CIBIL score. 750+ gets you the best rates and fastest approval. Below 650 makes approval difficult at most banks.
• Income and employment stability. Salaried applicants need salary slips and Form 16; self-employed applicants need ITRs and business financials, usually for the last 2 to 3 years.
• Existing EMI obligations. Lenders look at your total EMI-to-income ratio, usually wanting your combined EMIs (including the proposed home loan) to stay under roughly 40% to 50% of take-home income.
• Age and tenure fit. Your loan tenure typically has to end before you turn 65 to 70, depending on the lender, so older applicants get shorter maximum tenures.

10. Is it better to buy a bigger house now or a smaller one and upgrade later?

There is no universal answer, but the math is worth doing honestly. A bigger loan today means a bigger EMI locked in for decades, more interest paid in absolute terms, and less room in your monthly budget for savings and investing during your prime earning and compounding years. A smaller, affordable home loan now, paid down aggressively, followed by an upgrade later funded partly by equity from the first property, is often the lower-risk path for someone early in their career.

Core rule: size your home loan to your CURRENT income, not your hoped-for future income. If a raise comes, prepay, do not upgrade your lifestyle into a bigger EMI before the raise actually lands.
