Long-Tenure Home Loans: The Hidden Trade-Off Between Lower EMIs and Higher Lifetime Costs

Home Loans Get More Affordable, But at What Cost?

Buying a home has become increasingly challenging in recent years due to rising property prices outpacing income growth. For many first-time buyers, the difficulty extends beyond securing a down payment to managing the monthly Equated Monthly Installment (EMI) payments. To make home loans more affordable on paper, lenders are increasingly offering longer repayment tenures of up to 25-30 years and step-up EMI plans that start with lower repayments and increase gradually over time.

These structures can make buying a home easier today, but they can also increase the overall cost of borrowing and create new risks later on. Younger homebuyers struggling to keep up with rising property prices are particularly attracted to these options, as they can lower the initial EMI burden by 10-25 percent, allowing buyers to qualify for a larger loan than they otherwise could.

According to Vikram Singh, Executive Director at Urban Money, these options are most commonly used by salaried borrowers aged 25-40, especially first-time buyers in cities where home prices have risen sharply. Many borrowers today prioritize cash-flow comfort over minimizing total interest costs, expecting their incomes to rise over time and allowing them to either absorb higher EMIs or prepay a part of the loan later.

However, extending a loan tenure can significantly increase the overall cost of borrowing. For example, taking a longer tenure of 30 years instead of 20 years can increase the total interest paid over the life of the loan by more than 60 percent, despite a lower EMI. "Many borrowers focus on the lower EMI because it is immediately visible, while the increase in total borrowing cost often receives less attention," says Simranjeet Singh, CEO, SME and Retail Business, Anand Rathi Global Finance.

Step-up EMI plans are another option that can help borrowers qualify for larger loans without taking on a high EMI burden from day one. These plans assume income will increase over time and start with lower EMIs during the initial years of the loan, which then rise in predefined stages, typically aligning with expected salary growth. However, these structures also introduce a dependency on future earnings and can create new risks if income growth does not materialize.

Industry experts say these structures are likely to work best for younger salaried borrowers who expect their incomes to grow steadily over the coming years and have enough savings to deal with unexpected setbacks. Borrowers should be careful about treating future salary hikes as a certainty and should keep total EMI obligations within 30-35 percent of take-home income.

Before opting for a longer tenure or step-up EMI plan, borrowers should ask themselves a simple question: Am I choosing this because it genuinely fits my budget, or because it allows me to borrow more than I otherwise could?
