Gross yield is a starting line, not the finish

Annual rent divided by purchase price is easy to quote and easy to abuse. It ignores vacancy, tenant turnover painting, society special levies, property tax, insurance, and your time. Investors who live by gross yield alone are surprised when the first empty quarter arrives.

The rental ROI tool pushes you to include more of those frictions. It still cannot model legal risk, liquidity, or neighborhood trajectory—use it as a disciplined screen.

Leverage changes everything

A high gross yield can turn mediocre on cash-on-cash once EMI, registration, and opportunity cost of down payment enter. Conversely, moderate gross yield with sensible leverage and stable tenants can work. Model financing explicitly instead of assuming rent covers EMI because it rhymes.

Vacancy stress tests

Assume at least two weeks to one month a year unless you have evidence otherwise. Tier-2 markets and new supply can gap harder. Run scenarios at zero, eight, and fifteen percent vacancy to see how fragile the deal is.

Principal is not income

EMI contains principal repayment, which builds equity but is not spendable return. Separate cash flow from balance sheet when you brag or worry about a property.

Bottom line

Good screening is boring: include conservative costs, stress vacancy, and compare financed versus unlevered outcomes. If the deal only works on rosy assumptions, pass or renegotiate.
