Practical Strategies to Save Money
Aim for 20%–25% Down Payment
Paying a higher upfront down payment reduces principal (P), cuts interest outgo, and avoids costly lender risk surcharges.
Make 1 Extra EMI Prepayment Annually
Prepaying 1 extra EMI every year (or 10% principal prepayments) reduces a 20-year home loan tenure by nearly 4 years.
Maintain 750+ CIBIL Score
Top tier credit scores qualify for special interest rate concessions (up to 0.5% lower rate), saving lakhs over multi-decade tenures.
Co-Apply with Spouse for Double Tax Relief
Joint home loans allow co-borrowers to each claim up to ₹2L (Sec 24b) and ₹1.5L (Sec 80C), doubling total household tax savings to ₹7L/year.
Include Stamp Duty in TCO Budget
Always budget 5%–7% for stamp duty, registration, GST, and legal fees to prevent cash crunch during property registration.
Common Mistakes to Avoid
Critical financial oversights that reduce long-term returns
Underestimating extra upfront costs such as stamp duty, registration charges, GST, and interior fitting expenses.
Opting for the maximum 30-year tenure without evaluating cumulative interest outgo.
