The 1 BHK has quietly returned to Bengaluru's launch calendar. For several years, the market's centre of gravity moved firmly towards larger homes. In 2026, some of the city's biggest developers are again including one-bedroom units in large projects, aimed at a buyer who wants a branded address at a lower ticket size, and at investors who want rental income without a ₹2 crore cheque.

That makes the question worth asking carefully: is a 1 BHK in a Bangalore new launch a good investment in 2026? Our answer is that it can be, under specific conditions, and that the case rests on rent and resale depth, not on headline appreciation.

Why 1 BHKs are back in launches

The clearest public example is Prestige's Evergreen at Prestige Raintree Park. In a press release filed with the National Stock Exchange on 14 January 2026, Prestige Estates said the project spans about 24 acres with around 2,000 apartments and 3.2 million sq ft of saleable area, offering one- to four-bedroom homes priced from approximately ₹92 lakh, with an estimated gross development value of about ₹5,000 crore.

The filing is explicit about intent. It says Evergreen expands the product mix to include smaller-format residences to enable broader customer participation, following the larger-format Raintree Park launch of September 2024. In other words, developers have noticed that the ticket size of a premium address has run ahead of many buyers, and smaller units are the response.

The counter-trend you should know about

This is happening against a strong move towards bigger homes. ANAROCK data, as reported in trade coverage in 2026, shows the average flat size across India's top seven cities rising about 17% in two years, from 1,420 sq ft in 2023 to roughly 1,676 sq ft in 2025, with Bengaluru recording growth in the low twenties in percentage terms over the same period.

ANAROCK's Q2 2026 Bengaluru data reinforces the direction: the high-end ₹1.5 crore to ₹2.5 crore band made up 43% of new launch supply in the quarter, with the ₹80 lakh to ₹1.5 crore band at 28%. One-bedroom units remain a small share of what is being built. That scarcity can help resale, but it also means the buyer pool for a 1 BHK is narrower than for a 2 BHK.

What 1 BHKs cost and earn, by corridor

ANAROCK's micro-market reports publish typology tables that are useful for setting expectations. They are dated, so use them as ranges rather than current quotes.

  • Sarjapur Road (ANAROCK, January 2025): 1 BHK of 500 to 704 sq ft at ₹55 lakh to ₹85 lakh, renting at ₹15,000 to ₹30,000 a month.
  • Electronic City (ANAROCK, May 2024): 1 BHK of 500 to 700 sq ft at ₹22 lakh to ₹45 lakh, renting at ₹7,000 to ₹14,000 a month.
  • Devanahalli (ANAROCK, July 2024): 1 BHK of 700 to 850 sq ft at ₹30 lakh to ₹40 lakh, renting at ₹10,000 to ₹18,000 a month.
  • Current indicative rents (Square Yards, June 2026): about ₹29,150 a month for a 1 BHK on Sarjapur Road and about ₹23,150 in Harlur. These are listing-based averages and vary widely by project.

The yield arithmetic, done honestly

On ANAROCK's Sarjapur Road midpoints, a 1 BHK at about ₹70 lakh renting at about ₹22,500 a month earns a gross yield near 3.9%. That is our arithmetic. Subtract maintenance, property tax, a month of vacancy every year or two, and brokerage on re-letting, and the net figure is materially lower.

For context, ANAROCK estimated Bengaluru's city-wide residential rental yield at 4.6% in Q2 2026, up from 3.6% in 2019, as reported by Business Today in August 2026. Smaller units often achieve a slightly higher rent per square foot than larger ones, which is the core of the 1 BHK case. But a premium-branded 1 BHK bought near ₹90 lakh to ₹1 crore needs a strong rent to match the city average, and new launches are priced at today's rates for delivery several years out.

There is also a supply-side reason for caution. ANAROCK recorded about 21,700 units launched in Bengaluru in Q2 2026, up about 42% year-on-year, while available inventory rose about 34% year-on-year to roughly 79,200 units, an overhang of about 15 months. When new completions arrive in volume, landlords of small units compete hardest, because 1 BHK tenants move more often and have more choice.

Where a 1 BHK makes sense

  • Close to dense employment: within a short commute of large technology parks, where single professionals and couples rent without cars.
  • In large, well-run projects: a 1 BHK benefits from the amenities and maintenance standards of a big community, and it re-lets faster when the building is known.
  • Near operating metro: a 1 BHK tenant is more likely to rely on public transport. The Yellow Line to Electronic City opened in August 2025 and the Purple Line to Whitefield has run its full length since October 2023 (per ANAROCK's Whitefield report).
  • With realistic size: ANAROCK's tables show 1 BHKs from about 500 sq ft. Below that, the unit competes with studios and co-living, which is a different and more volatile market.

Where a 1 BHK is a weaker bet

  • Far from jobs, where the natural tenant is a family wanting two bedrooms.
  • In localities with unresolved basic services. In Varthur, Gunjur and nearby villages, Cauvery Stage V water had still not reached many homes regularly as of April 2026, according to News Karnataka. Tenants notice tanker bills.
  • In very small projects where 1 BHKs are a token share, which limits comparable resale evidence.
  • When the purchase is stretched. If the EMI only works with a tenant in place from day one, the investment carries risk you may not want.

1 BHK under construction in Varthur and Whitefield: specific checks

Our visitor data shows interest in under-construction 1 BHKs around Varthur, which matches the Evergreen launch. Before booking any such unit, check the registered completion date on the Karnataka RERA portal, the phase in which your tower sits, and how water will be supplied at handover. Ask whether the price quoted includes car parking, since many 1 BHK buyers either do not need one or find it billed separately.

For remote buyers, including the Mumbai-based investors we see on our site, add three more checks: who will manage the tenancy, how maintenance dues will be paid, and whether the developer offers a leasing desk at handover. These matter more for a 1 BHK, where a lost month of rent is a larger share of annual income.

Resale: the part most buyers skip

Exit depth is the main risk in a 1 BHK. The buyer for your unit in seven years is likely to be an investor or a first-time owner with a tight budget. They will compare your flat with newer 1 BHKs in the next round of launches. A 1 BHK in a recognised project close to employment tends to hold its appeal. A 1 BHK in a peripheral project with few comparable sales can be slow to sell.

If you are buying primarily for capital growth, a well-chosen 2 BHK usually offers a deeper resale market. If you are buying primarily for rent and a lower entry ticket, a 1 BHK can be the more efficient choice.

Our view

A 1 BHK in a Bangalore new launch is a reasonable investment when it sits in a large, credible project near jobs or operating metro, is sized above about 500 sq ft, and is bought at a price where gross rent clears roughly 3.5% to 4% on day one. It is a weak investment when it is bought far from employment, at a premium-brand price that needs years of appreciation to make sense. Decide what you want the flat to do before you decide which launch to join.
