Is buying an under-construction flat really cheaper than a ready-to-move flat?

Not always. While the base ticket price of an under-construction flat is often 10% to 15% lower, you must add 5% GST (which is 0% for ready flats with OC), pre-EMI interest paid during the 3–4 year construction period, ongoing monthly house rent, and the risk of delayed delivery. In many cases, the total 3-year financial outflow is equal to or higher than buying a ready home.

What is the GST difference between under-construction and ready properties?

Under-construction residential properties attract 5% GST (1% for affordable housing). Ready-to-move properties that have received a valid Completion Certificate (CC) or Occupancy Certificate (OC) from BBMP/BDA have zero GST (0%).

When do home loan tax benefits start for under-construction properties?

Tax deductions on home loan principal (Section 80C) and home loan interest (Section 24b up to ₹2 Lakhs/year) can only be claimed starting from the financial year in which possession/construction is completed. Interest paid during the pre-construction period can be claimed in 5 equal annual installments after possession.

What is Pre-EMI vs Full EMI?

Pre-EMI is the monthly interest paid to the bank solely on the loan amount disbursed to the builder based on construction milestones. Full EMI begins after possession and includes both principal repayment and interest. Pre-EMI does not reduce your loan principal.

What is the rental yield advantage of a ready-to-move apartment?

A ready apartment generates immediate rental income (or saves you from paying house rent) starting on Day 1. In Bengaluru, average gross rental yields range from 3.5% to 5.2% annually, representing ₹4L–₹7L per year in cashflow that is lost during an under-construction waiting period.
