Home Loan and Mortgage Guide: Everything You Need to Know Before Buying a Flat
Rahul bought a flat at 25. No research. No comparison. His teammate said "bro, you should invest in property" and two weeks later, Rahul was signing papers for a 2BHK in Pune at ₹65 lakh with a 20-year home loan.
Monthly EMI? ₹54,000. His salary as a domestic cricketer? ₹1.2–2.5 lakh depending on the season. In peak months, the EMI felt manageable. In off-season? He was eating Maggi for dinner and borrowing from friends for fuel.
"I thought buying a flat is what adults do," Rahul says now. "Nobody told me that understanding your home loan is more important than choosing the flat."
If you're planning to buy a home, or already have an EMI running, this is the guide Rahul wishes he'd read first.
What Is a Home Loan (Mortgage)?
That last part is important. Your home isn't "yours" until the loan is paid off. Until then, it's the bank's collateral. Rahul didn't fully grasp this until he saw the hypothecation clause in his agreement.
How Much Can You Actually Borrow?
Banks typically lend 60–80% of the property value (called the Loan-to-Value ratio, or LTV). You need to cover the rest as a down payment.
For a ₹65L flat:
- 80% LTV = ₹52L loan, ₹13L down payment
- 75% LTV = ₹48.75L loan, ₹16.25L down payment
Banks also check your repayment capacity:
- Your EMI should not exceed 40–50% of your monthly take-home income
- They look at existing loans, credit card dues, and your credit score (750+ gets you the best rates)
- Irregular income (like Rahul's cricket earnings) means stricter assessment
Fixed Rate vs Floating Rate Home Loans
| Feature | Fixed Rate | Floating Rate |
|---|---|---|
| Interest rate | Locked for the entire tenure (or a fixed period) | Changes with RBI repo rate and bank benchmarks |
| EMI | Same every month, predictable | Can increase or decrease |
| Starting rate | Usually 0.5–1% higher than floating | Lower initial rate |
| Best when | Interest rates are expected to rise | Interest rates are stable or falling |
| Availability | Some banks offer for 2-5 year periods | Most common in India |
The Tax Benefits of Home Loans
This is the one thing that makes home loans slightly less painful. But only under the old tax regime.
Section 24(b). Interest Deduction:
- Up to ₹2 lakh per year deduction on home loan interest (old regime only)
- Property must be self-occupied
- For let-out property, the entire interest is deductible (no ₹2L cap)
Section 80C. Principal Repayment:
- Up to ₹1.5 lakh per year deduction on principal repaid (old regime only)
- Shared with other 80C instruments like PPF, ELSS, EPF
Section 80EEA. Additional Interest (for first-time buyers):
- Additional ₹1.5L interest deduction for affordable housing (stamp duty value up to ₹45L)
- This section has limited applicability now: check the latest budget
The Real Cost of a Home Loan
People look at the flat price. They forget the real cost.
| Cost Component | Typical Amount | Notes |
|---|---|---|
| Flat price | ₹65,00,000 | What the builder quotes |
| Registration & Stamp Duty | ₹3,50,000-5,00,000 | 5-7% of property value (varies by state) |
| Loan processing fee | ₹30,000-65,000 | 0.5-1% of loan amount |
| GST (under-construction) | ₹3,25,000 | 5% for affordable, 12% for others (if applicable) |
| Maintenance deposit | ₹1,00,000-2,00,000 | Society maintenance advance |
| Interior & furnishing | ₹3,00,000-8,00,000 | The part everyone forgets to budget |
| Total interest paid (20 years) | ₹45,00,000-55,00,000 | Yes. You will pay nearly the flat price again in interest |
That last row. Read it again. On a ₹52L loan at 8.5% for 20 years, you'll pay approximately ₹50L in interest. Your ₹65L flat actually costs you ₹1.15 crore+. Rahul didn't know this until Year 3.
Prepayment: The Best Financial Decision You'll Make
Under RBI rules, there's no prepayment penalty on floating rate home loans in India. This is huge.
Every extra rupee you pay toward principal directly reduces your total interest.
Prepayment strategies that work:
- Throw every bonus, increment hike, and windfall at your home loan
- Even ₹5,000/month extra reduces tenure by years
- Make one extra EMI per year (from your annual bonus)
- Always prepay the principal: not just advance EMIs
Choosing the Right Home Loan
Compare these across at least 3-4 banks:
- Interest rate (EBLR + spread)
- Processing fee
- Prepayment terms
- Insurance bundling (say no to overpriced bundled insurance)
- Foreclosure charges (should be nil for floating rate)
Banks to check: SBI, HDFC, ICICI, Bank of Baroda, LIC Housing, PNB Housing, and any housing finance company your builder recommends (but independently verify their rates).
Common Home Loan Mistakes
- Buying too expensive a flat: If your EMI exceeds 30% of take-home, you're house-rich and cash-poor
- Not comparing lenders: A 0.3% rate difference on ₹50L over 20 years = ₹4-5L saved
- Ignoring the total interest: Focus on total cost (principal + interest), not just EMI
- Not prepaying when possible: Every year you don't prepay, you pay the bank more interest
- Skipping home insurance: Fire, earthquake, flood. Your flat is your biggest asset. Insure it
- Forgetting about the new tax regime: If you're on the new regime, home loan tax benefits don't apply. Plan accordingly
- Buying because "that's what you do": Renting is not throwing money away. Buying at the wrong time IS
Key Takeaways
- Keep total EMIs under 30% of your take-home (not the bank's 40-50% limit)
- Home loan interest deduction under Section 24(b) is up to ₹2L/year: old tax regime only
- Principal repayment qualifies under 80C up to ₹1.5L/year: old tax regime only
- No prepayment penalty on floating rate loans: use every bonus to reduce principal
- The real cost of a home loan is nearly double the flat price once you add interest
- Compare at least 3-4 lenders and get pre-approved before visiting builders

What Rahul Would Tell You
"Buy a home when you can genuinely afford it. Not when the bank says you can. Not when your teammate says you should. Not because your parents want to show photos at family functions. Run the numbers. Calculate the total cost. Keep your EMI low enough that you can still invest, travel, and live."
