Rental property investment means buying a home, shop or office to earn regular rent and, over time, capital appreciation. The right question is not how much rent a property will earn, but what it will return after vacancy, maintenance, taxes and loan costs. That net figure, not the headline rent, decides whether an investment works.

This guide shows how to calculate real returns with a worked Mumbai example, how residential and commercial rentals compare, how rental income is taxed, and what to check before you buy. It draws on Tat:vm's experience building homes and workplaces across the city.

Key Takeaways

  • Judge a property on net yield, not rent. Vacancy, society charges, property tax and brokerage can cut returns well below the headline figure.
  • Tax changes the answer. Rental income is taxed as income from house property, with a 30% standard deduction on net annual value and a deduction for home loan interest, as set out by the Income Tax Department
  • Commercial assets are going mainstream. Offices and shops typically offer stronger rent than homes but need more capital and longer vacancy buffers.
  • Location drives both income and growth. Metro access, jobs and schools widen the tenant pool and support appreciation.

How Do You Calculate the Real Return on a Rental Property Investment?

Start with gross rental yield: annual rent divided by the purchase price, multiplied by 100. Then subtract every recurring cost to reach net yield. Net yield is the number to compare against a fixed deposit, a mutual fund or another property.

Where the rest of the return comes from

Rent is only half of the story. The property may also appreciate, depending on location, infrastructure and demand. Your total return is net yield plus appreciation, but treat appreciation as a possibility, not a certainty. A property that rents well is not always the one that grows fastest in value, and markets move at different speeds even between neighbouring suburbs.

Is Commercial or Residential Property Better for Rental Income?

Commercial property usually earns higher rent relative to its price and comes with longer leases, but it needs more capital, carries longer vacancies between tenants and depends on business cycles. Residential property earns less but is easier to buy, finance, rent and resell. Choose based on your capital, your risk appetite and how long you can wait for a tenant.

Speaking to Times Property in September 2026, Tat:vm founder Raahul Maroo said: "Commercial real estate is shifting from an institutional asset class to an attractive mainstream investment opportunity." In his view, strong leasing demand and rising rentals make quality commercial assets compelling for investors who want both regular income and long-term appreciation.

  • Residential flats have a lower entry ticket and lower rent relative to price. Leases typically run 11 months to 3 years, vacancy gaps are shorter thanks to a wide tenant pool, and tenants are individuals and families. The owner furnishes the home, if at all, and resale is easier.
  • Commercial offices and shops need a higher entry ticket but usually earn more rent relative to price. Leases often run 3 to 9 years with lock-ins, and tenants are companies, often with escalation clauses. The tenant usually pays for fit-out, but vacancy gaps are longer, the tenant pool is narrower, and resale is slower.

Which one suits you

  • Choose residential if this is your first investment, you want a smaller ticket, or you may need to sell within a few years.
  • Choose commercial if you have larger capital, can hold for the long term, and can absorb a few months' vacancy between corporate tenants.

For commercial investors, well-connected micro-markets matter most, because tenants now prioritise commute times. That is why projects such as the Commercial Marine Lines development in South Mumbai and the street-facing retail at Mixed-Use Ghatkopar sit close to rail and metro links. Our guide to commercial office space in Mumbai explains what today's SME tenants look for.

How Is Rental Income Taxed in India?

Rent from a flat, shop or office you own is taxed under the head "income from house property". From the annual value, you can deduct municipal taxes you actually paid, a flat 30% standard deduction on the net annual value, and interest on a loan taken to buy or build the property. The balance is added to your income and taxed at your slab rate.

The Income-tax Act, 2025 applies to income earned from 1 April 2026. It renumbers the sections but keeps these core rules, as explained by the Income Tax Department . A few points investors often miss:

  • The 30% deduction is automatic. It covers repairs and upkeep, so you cannot claim those expenses separately on top of it.
  • Loan interest on a let-out property is deductible without the Rs 2 lakh cap that applies to self-occupied homes. However, how much of a resulting loss you can set off against salary or other income depends on the tax regime you choose; under the default new regime, it cannot be set off against other heads.
  • Business tenants deduct TDS on rent. Check that it appears in your annual tax statement before filing.
  • GST applies to commercial rent once a landlord's taxable turnover crosses the registration threshold. Residential rent to a family living there is generally exempt. The CBIC GST portal carries the current notifications.

A worked view after tax

Take the flat above with net income of Rs 3,67,500 before loan costs. Tax is calculated on the rent after property tax and the 30% deduction, not on the net figure in our table, and then any eligible loan interest comes off. Two investors with the same flat can end up with very different post-tax returns depending on their tax slab, regime and loan. Run your numbers with a chartered accountant before you buy; this guide is general information, not tax advice.

What Should You Check Before You Buy a Rental Property?

Check the location's tenant demand, the project's legal standing, the developer's build quality and your full cost of ownership. These four decide both your rent and your resale value.

  • Map the tenant pool. Look for jobs, rail or metro stations, colleges and hospitals within a short commute. A wide tenant pool keeps vacancy gaps short.
  • Verify the project. For an under-construction or recently completed building, search it on the MahaRERA portal and read the approvals and quarterly progress reports.
  • Judge build quality. Leaks, cracks and failing lifts drive good tenants away and raise your repair bills. Ask how the developer plans and executes construction; our article on digital transformation in real estate explains what to look for.
  • Budget the full purchase cost. Stamp duty, registration, GST on under-construction property, legal fees and furnishing all raise your cost base and lower your yield.
  • Run net yield before tax and after tax, using the method above, with at least one month's vacancy a year.
  • Register every tenancy. In Maharashtra, Section 55 of the Maharashtra Rent Control Act, 1999 requires every leave and licence agreement to be registered, whatever its length, and stamp duty is paid through IGR Maharashtra. An unregistered agreement weakens your position in any dispute.
  • Verify your tenant. Complete police verification of tenants as required in Mumbai, and keep copies of ID and the registered agreement.
  • Keep a buffer. Hold three to six months of loan EMIs and society charges in reserve so a vacancy never forces a distress sale.

A rental property investment made with this discipline is far less likely to disappoint than one bought on a headline rent figure and a broker's promise.

Are REITs a Better Way to Earn Rental Income?

REITs are a useful alternative if you want rental income without buying, managing or financing a property yourself. They are listed trusts that own income-producing buildings, mostly offices, and distribute most of their earnings to unitholders. The trade-off is control: you own units in a portfolio, not an asset you can live in, redevelop or sell on your own terms.

REITs, including the newer small and medium REITs, are regulated by SEBI, which sets rules on disclosures, valuations and distributions. Many investors hold both: a directly owned flat or office for control and long-term appreciation, and REIT units for liquidity and diversification.

How Does Tat:vm Plan Buildings That Stay Easy to Rent?

A property keeps its tenants when it is well located, well built and pleasant to live or work in. At Tat:vm, we plan every project around five fundamentals: space, light, air, community and sustainability. For an investor, those translate into things tenants notice on the first visit: daylight, cross-ventilation, efficient layouts and lower running costs.

  • Homes near transport. The Ghatkopar residential project is designed around morning light and cross-breeze, minutes from the metro, which widens the tenant pool.
  • Workplaces in connected locations. Our commercial and mixed-use projects sit close to rail and metro links, where business tenants increasingly want to be.
  • Older buildings, new value. For owners of aging properties, redevelopment can turn a building with falling rents into a modern, rentable asset.
