A home loan (housing loan) is the primary financing tool for property buyers across India. Understanding the mechanics of home loans — particularly how interest rates are structured, what the RBI mandates regarding loan-to-value ratios, and the tax benefits available — can save buyers significant amounts over the loan tenure.
Loan-to-Value (LTV) Ratio — RBI Guidelines
The Reserve Bank of India (RBI) prescribes maximum Loan-to-Value ratios for home loans, which determines how much of the property's value a bank can finance. The buyer must fund the remainder as a down payment from their own resources:
| Loan Amount | Maximum LTV | Minimum Down Payment |
|---|---|---|
| Up to ₹30 lakh | 90% | 10% |
| ₹30 lakh to ₹75 lakh | 80% | 20% |
| Above ₹75 lakh | 75% | 25% |
Note: LTV is calculated on the lower of the property's market value or registered value. Stamp duty and registration charges are generally not included in the loan amount by most lenders (though some lenders include them — verify at the time of applying).
Interest Rate Structure: Fixed vs Floating
Floating Rate (Most Common)
Since October 2019, the RBI mandated that all new floating rate retail loans (including home loans) be linked to an external benchmark. Most banks use the Repo Rate (RBI's benchmark lending rate) or Treasury Bill rate as the external benchmark. The lending rate is expressed as:
Home Loan Rate = Repo Rate + Spread
The spread (bank's margin + credit risk premium) is fixed at the time of disbursement but can be revised by the bank only with borrower consent. When the RBI changes the Repo Rate, the home loan rate changes automatically and proportionately, typically within one loan reset cycle (usually quarterly).
Fixed Rate
Fixed rate loans maintain the same interest rate throughout the loan tenure (or for a specified period). They are generally priced higher than floating rates at the time of disbursement. They provide certainty of EMI but the borrower does not benefit if interest rates fall. Most lenders in India offer hybrid products: fixed for an initial period (3–5 years), then converting to floating.
Eligibility Criteria
Age: Typically 21–65 years (some lenders up to 70 for retirement-age applicants with co-borrowers).
Employment: Salaried employees with minimum 2 years of stable employment; self-employed professionals with minimum 3 years of business stability and ITR track record.
Credit score: CIBIL score of 750+ is preferred by most lenders for the best rates. Scores below 650 significantly reduce eligibility or increase rates.
Income: Net monthly income (after existing EMIs and statutory deductions) must comfortably cover the proposed EMI — most lenders target a Fixed Obligation to Income Ratio (FOIR) of 40–50%.
Property: The property must have clear title, approved plans, and must be acceptable as mortgage security to the lender. Banks will conduct a technical and legal valuation of the property before sanction.

Income Tax Deductions on Home Loans
Section 80C — Principal Repayment
The principal amount repaid on a home loan during the financial year qualifies as a deduction under Section 80C of the Income Tax Act, up to a maximum of ₹1,50,000 per year. This ₹1.5 lakh limit is shared with other Section 80C investments (PPF, ELSS, NSC, life insurance premium, etc.).
Section 24(b) — Interest Paid
Self-occupied property: Deduction on interest paid up to ₹2,00,000 per year.
Let-out (rented) property: The full interest paid is deductible. However, the set-off of losses from house property against other income (like salary) is capped at ₹2,00,000 per year; the balance loss can be carried forward for 8 years.
The property must be acquired or constructed within 5 years from the end of the financial year in which the loan was taken for the full deduction to apply.
Section 80EEA — Additional Deduction for First-Time Buyers (Verify Applicability)
Section 80EEA provided an additional deduction of ₹1,50,000 on home loan interest for first-time homebuyers purchasing affordable housing (stamp duty value ≤ ₹45 lakh), where the loan was sanctioned between 1 April 2019 and 31 March 2022. This section has not been extended beyond 31 March 2022 as of the last budget — buyers should verify the current position for any revival of this benefit.
Tips for South Indian Home Loan Borrowers
Compare rates across at least 4–5 lenders before deciding. Even a 0.25% difference in rate on a ₹50 lakh loan over 20 years translates to approximately ₹1.5–2 lakh in total interest savings.
Maintain your credit score above 750. Pay all EMIs and credit card bills on time for at least 12 months before applying.
Add a co-borrower (typically a spouse) to increase eligibility. If the co-borrower is also a co-owner, both can claim Section 24(b) deduction of up to ₹2 lakh each on their respective tax returns.
Ensure your property has clear legal title and all approvals before applying — banks will reject or significantly delay sanctions for properties with title or approval issues.
Pre-payment of home loans (without penalty, as mandated by RBI for floating rate loans) is one of the most effective ways to reduce total interest paid over the tenure.
