A practical 2026 comparison for Bangalore buyers - price gap, GST impact, delay risk, RERA protection and rental income - so you can decide between an under-construction flat and a ready home.

The core trade-off

Under-construction homes are usually cheaper per sq ft and offer staggered, construction-linked payment plans (often ~10-20% upfront).

  • Ready-to-move homes cost more but let you inspect the actual flat, avoid delay risk and start living/earning rent immediately.
  • Your choice hinges on budget, timeline, risk appetite and whether you need the tax/rental benefits of immediate possession.

GST: the biggest hidden cost difference

Under-construction residential property attracts 5% GST (non-affordable) or 1% GST (affordable), both without input tax credit.

  • Affordable housing definition in metros like Bengaluru: carpet area up to 60 sq m AND value up to ₹45 lakh.
  • GST is computed after a standard one-third deduction for land value, then the rate is applied to the remaining two-thirds.
  • Ready-to-move flats that already have an Occupancy Certificate are fully exempt from GST - as are resale flats and land.
  • The GST 2.0 revision effective 22 September 2025 left these residential rates unchanged at 1% and 5%.

Delay risk and how RERA protects you

A large share of Indian projects historically slip 1-3 years past their promised handover; delays mean paying rent and EMI simultaneously.

  • RERA Karnataka registration lets you verify approvals, timelines and quarterly progress at rera.karnataka.gov.in, and mandates escrow of 70% of collections for the project.
  • RERA also provides interest/compensation remedies for delayed possession - but recovery still takes time and effort.
  • Always confirm the RERA status is Approved before booking an under-construction unit.

What you can and can't verify

Ready-to-move: you can inspect actual construction quality, ventilation, view, water pressure, finishing and neighbourhood before paying.

  • Under-construction: you rely on the sample flat, brochure and RERA-registered specifications - delivery may differ in finish, view or amenities.
  • For ready flats, verify OC and completion certificate; for under-construction, verify RERA, approvals and the builder's delivery track record.

Rental income and returns

Ready-to-move generates rent from day one (Bangalore residential gross yields roughly 3.5-5.5%, higher near IT corridors).

  • Under-construction earns zero rent during the build and ties up capital, but can appreciate more in an infrastructure-led micro-market.
  • Factor in cost of carry (rent + EMI) during construction when comparing the lower under-construction price.

Which should you choose?

Choose ready-to-move if you need to move soon, want to avoid delay/GST and value certainty.

  • Choose under-construction if you have time, want a lower entry price and payment flexibility, and are backing a reputable RERA-registered builder in a growth corridor.
  • In 2026 Bangalore's high unsold inventory gives buyers negotiating power on both - use it.
