Frequently asked questions

What is a good monthly EMI result relative to rental income?
A common benchmark is that your monthly EMI should not exceed 70% to 80% of your monthly rental income, leaving room for operating expenses and generating positive cash flow. If EMI is higher than rental income, the property will have negative cash flow each month, meaning you are subsidizing the mortgage from other income sources while relying on capital appreciation.
How accurate is this mortgage EMI calculator?
The calculator uses the standard reducing-balance EMI formula used by banks and mortgage lenders worldwide. It assumes a fixed interest rate for the full tenure. Variable-rate mortgages will produce different actual EMIs as rates change, and some lenders may add processing fees or insurance that affect the total monthly outflow.
What does a very high monthly EMI mean for my investment?
A high EMI relative to rental income means your investment property will have negative monthly cash flow, requiring you to top up the shortfall from other sources each month. While this can be acceptable if significant capital appreciation is expected, it creates financial pressure and increases investment risk if rental income falls or the property is vacant for extended periods.
How can I reduce my monthly EMI?
The three main ways to reduce EMI are: negotiating a lower interest rate with your lender or refinancing when rates drop, extending the loan tenure to spread payments over more months, or making a larger down payment to reduce the principal loan amount. IONROI tracks your full EMI schedule and marks each payment against the correct period so your ROI analytics remain accurate as you pay down the loan.
