Interest Rate Insights: Key Factors in Home Loan Rate Determination

India has one of the world’s most rapidly expanding economies, which is accompanied by a thriving real estate market thanks to the builders and developers in Mumbai. Nonetheless, the home loan interest rates in India have significant variations which are contingent upon several determinants.

In this article, we will dive deep into the fundamental factors that govern the interest rates on home loans in India. Given that acquiring a residence in today’s real estate market constitutes a substantial financial investment and a prolonged fiscal commitment. As the demand for homes is escalating by the day, feasibility has become a paramount concern for people. A multitude of elements influence the choice to purchase a home, encompassing the interest rate, repayment duration, and equated monthly installment (EMI) sum.

Given that home loans extend over prolonged periods, often up to 30 years, the cumulative interest can create a lasting financial impact. Consequently, the expense associated with homeownership is intrinsically linked to the prevailing interest rate.

Furthermore, understanding how home loan interest rates are computed requires you to examine these specific factors before you seek a home loan.

Key determinants influencing your home loan interest rate

Carefully evaluate the following aspects to secure the most favourable home loan interest rates.

Credit Score (CIBIL Score)

Your CIBIL Score is a comprehensive assessment of your credit history, existing liabilities, and borrowing behaviour. A higher CIBIL Score signifies creditworthiness to the lender, rendering you eligible for competitive home loan interest rates. Conversely, a lower CIBIL Score indicates heightened credit risk for the lender, prompting them to levy a higher interest rate.

It is worth noting that outstanding debts account for 30% of your CIBIL Score. Moreover, if your current debts encompass 50% to 80% of your monthly income, you may be categorised as a high-risk borrower. In such cases, lenders may impose a higher interest rate on your home loan to mitigate their lending risks. Managing your debt to maintain an income-to-debt ratio below this threshold enhances your eligibility for lower home loan interest rates.

Income Stability

Another factor that plays a pivotal role in determining your loan eligibility and interest rate is your income stability, regardless of whether you are a salaried employee or a self-employed professional. Your income profile assists lenders in assessing your credit risk and capacity to repay the loan. Typically, lenders favour individuals with a consistent monthly income to meet their eligibility criteria. Self-employed professionals, such as doctors, lawyers, and chartered accountants, with stable businesses and favourable CIBIL Scores, may qualify for competitive interest rates. Similarly, salaried individuals in secure employment positions can secure favourable interest rates on their home loans.

Loan-to-Value (LTV) Ratio

The Loan-to-Value (LTV) ratio represents the percentage of the loan amount that can be obtained in relation to the current market value of your property. Per Reserve Bank of India (RBI) directives, lenders can provide financing of up to 90% of the property value for loans up to Rs. 30 lakh. For loans ranging from Rs. 30 to 75 lakh, 80% financing is available, while loans exceeding Rs. 75 lakh can be funded up to 75%.

While these figures denote the maximum financing limits, borrowing beyond them can impact your interest rate due to the increase in the principal amount. Furthermore, a higher LTV ratio signifies greater credit risk for the lender, which can be managed by imposing a higher home loan interest rate. Conversely, increasing your down payment to 30% can reduce your LTV ratio, thereby decreasing the interest component.

Types of Interest Rates

It is advisable to understand the implications of various interest rate types offered by lenders before making a selection. Opting for a floating interest rate allows you to benefit from RBI repo rates during favourable market conditions, resulting in lower EMIs. On the other hand, selecting a fixed interest rate means that the interest component of the loan remains constant throughout the tenure, unaffected by changes in RBI repo rates. Hybrid or mixed interest rates typically commence with a fixed interest rate for a few years before transitioning to floating rates.

In essence, lenders benchmark interest rates based on specific internal and external factors. According to RBI guidelines, lenders can base their floating rates on either the Marginal Cost of Funds-Based Lending Rate (MCLR) or the Repo-Linked Lending Rate (RLLR). MCLR serves as an internal benchmark rate, with lenders determining home loan interest rates based on their lending costs.

RLLR is linked to the RBI’s repo rates and monetary policies, which may undergo changes approximately every three months. In the event of a reduction in the Repo Rate by the RBI, the interest rate on your loan will decrease if you have chosen externally benchmarked interest rates.

Repayment Tenure

The duration of your home loan is another influential factor affecting the interest rate. Home loan interest rates exhibit an inverse relationship with repayment periods—shorter tenures are associated with lower rates, while longer terms entail higher rates. The rationale behind this is straightforward. Lending a substantial home loan for a luxury project from home developersfor a shorter duration poses less risk for the lender. Conversely, extending the loan term heightens the lender’s risk thus increasing the likelihood of defaults. Therefore, although EMIs may be higher for shorter tenures, you can save on the interest component of the loan due to the lower home loan interest rates.


Home loan interest rates are influenced by several elements, including credit scores, loan amounts, down payments, loan durations, and the chosen loan type. Furthermore, external economic conditions, such as inflation, overall economic growth, and governmental policies, exert a significant impact on these rates. By meticulously examining these variables, prospective homebuyers can make well-informed decisions that align with their financial objectives. This facilitates the realisation of their dreams of homeownership with builders in Mumbai, like Sunteck Realty. It is of utmost importance to consider the lasting consequences of interest rates and make choices that ensure financial stability over the entirety of the loan tenure.
