What you pay, and when
an exampleThis is just an example of the cash flows for buying a home, not a quote or a payment demand. Your agreement and the developer's schedule decide the actual amounts.
In an under-construction project, you don't pay everything on day one. Under the MahaRERA model agreement, the developer can only ask for money as each stage is finished: about 10% at booking, 30% at agreement, then more as the plinth, slabs, walls, fittings and lifts are done, and the last 5% at possession. The more a building is finished, the more you pay up front.
Example: 2 BHK · 655 sq ft at ₹2.60 Cr (the price recorded above).
- ✓ Plinth complete45% paid by then
- ✓ Slabs complete70% paid by then
- ✓ Walls, plaster & flooring75% paid by then
- ✓ Sanitary fittings80% paid by then
- ✓ Staircases, lift wells & lobbies85% paid by then
- ✓ Lifts, pumps, plumbing & elevation95% paid by then
- ○ Possession100%
With a home loan: banks usually fund up to 75% (₹1.95 Cr here), released stage by stage, so your own money is about ₹65.0 L plus stamp duty and GST. Until possession you pay interest only on what the bank has released; after that the full EMI is roughly ₹1.69 L/month (8.5%, 20 years).
Indicative only. Rates, GST (1% on affordable homes), loan eligibility and the stage schedule vary. Plan your cash flow with an advisor before you book.
