30 Rule in Real Estate: What It Means and How It Affects Your Property Decisions
When people talk about the 30 rule, a simple guideline used by property investors and renters to manage housing costs. It’s not a law, but a practical benchmark that tells you how much of your income should go toward housing—whether you’re renting or buying. If you’re earning $5,000 a month, the 30 rule says you shouldn’t spend more than $1,500 on rent or mortgage payments. Simple, right? But here’s the catch: it doesn’t always fit real life. In places like Mumbai’s Mulund, where rents are rising fast and salaries don’t keep up, sticking to 30% might mean living far from work, or skipping essentials like groceries or transport.
The rental income, the money you earn from leasing out a property is where the 30 rule gets really useful—for investors. If you’re buying a property to rent out, this rule flips: your monthly rent should be at least 30% of the property’s total purchase price divided by 12. So if you pay ₹80 lakh for a flat, your rent should hit ₹20,000 a month just to break even on costs like maintenance, taxes, and vacancies. Most investors aim higher—35% to 40%—because the 30 rule doesn’t account for repairs, property management, or periods when the unit sits empty.
Then there’s the cash flow, what’s left after all expenses are paid from rental income. A property might look great on paper, but if your cash flow is negative after paying the loan, insurance, and repairs, you’re losing money every month. The 30 rule is a starting point, not the finish line. Many smart buyers in Mulund ignore it entirely and focus on actual numbers: What’s the net rent after taxes? How long until the mortgage is paid off? What’s the vacancy rate in this building?
Some people use the 30 rule to avoid overpaying. Others use it to spot bad deals. If a landlord asks for ₹30,000 rent on a ₹40 lakh apartment, that’s 9% of the value per year—way below the 12% target most investors chase. That’s not a good investment, no matter how nice the kitchen looks. On the flip side, if you’re renting and your rent is 40% of your income, the 30 rule is your warning sign. It’s not about being perfect—it’s about being aware.
