Step 1: Total Up Your Whole Investment Cost
Your total cost means the final property price plus all extra expenses like taxes, paperwork, and other fees.
In Chennai, you usually pay about 7% stamp duty and 2% registration charges. If you use a broker, you may also pay around 1% to 2% commissionIt is also important to include small costs like repairs, inspections, and basic fixes at the start. This helps you plan your budget better and avoid money shortages later.
Step 2: Figure Out Your Yearly Rental Income
To find yearly rent, just times your monthly rent by 12.
In OMR, a 2 BHK flat usually gets ₹25,000 to ₹35,000 rent per month. In Anna Nagar, it can go above ₹55,000 per month.
It is also good to keep a small 5% buffer in your calculation for times when the property stays empty between tenants.
Step 3: Subtract Your Yearly Expenses
Yearly expenses are the total ongoing costs needed to run and maintain your property. This list includes your Chennai Corporation property tax, clean water taxes, monthly building maintenance fees, and building insurance. Forgetting to subtract these real costs will make your final profits look much bigger than they actually are.
Step 4: Find Your True Net Annual Profit
Subtract all your yearly expenses from your total rent income to get your real profit.
If you are selling the property, take your final selling price and subtract everything you spent on buying and holding it.
The remaining amount is your actual profit for that year.
Step 5: Apply the Simple ROI Formula
The standard math formula to find your return on investment is: For example, if a house in Medavakkam makes a clean profit of ₹4,80,000 a year and costs you ₹80,00,000 total to buy, your clear ROI is exactly 6%.
