Buying a rental property without calculating your returns first is like opening a business without a financial plan. Two numbers matter most before you commit: rental yield and return on investment. Understanding both, and the difference between them, will save you from expensive mistakes.
What rental yield tells you
Rental yield is the annual rental income from a property expressed as a percentage of its value or purchase price. It shows you how much money your property generates relative to what it costs. There are two versions, and both matter.
Gross rental yield is the simpler calculation. Divide the annual rental income by the property value, then multiply by 100. If a property costs 50 million naira and generates 4 million naira annually in rent, the gross yield is 8 percent.
Net rental yield subtracts your property expenses from the rental income before calculating the percentage. This gives you a more accurate picture of your actual return, since maintaining virtually any property comes with costs. Common expenses to deduct include agency fees, maintenance, service charges, and vacancy periods.
What ROI tells you
ROI measures how much return you earn each year on the money you actually invested. Use your net income and total investment figures as follows: ROI equals net annual income divided by total investment, multiplied by 100. Total investment must include the purchase price, agency and legal fees, renovation costs, and any other acquisition expenses. Leaving these out will make your returns look better than they are.
For a more complete picture, include appreciation in your ROI calculation using this formula: ROI equals net income plus appreciation, divided by total investment, multiplied by 100.
What counts as a good return
A rental yield of 7 to 8 percent or higher is generally considered excellent, typically found in emerging markets or well-located properties with strong demand. A yield between 5 and 7 percent is good in stable markets, while anything below 4 percent may only be acceptable where strong capital appreciation is expected.
Always run both calculations before signing anything. The asking price is what a seller wants. The yield and ROI are what the property is actually worth to you.
