Neopolis High-Rise Math: Land Auction Rates & Pre-EMI Outlay

I've been building a price tracking model for Neopolis and Kokapet high-rises over the last few weeks. With HMDA land auctions hitting over ₹100Cr to ₹151Cr per acre in Neopolis, developers are launching at ₹11,000 to ₹15,000/sq.ft base rates (like in The Cascades Neopolis and Godrej Neopolis). On one hand, commercial data looks solid with 111% YoY REIT growth and 50-70 new GCCs moving into Financial District, but on the other hand, my scrapers show around 27 months of residential inventory overhang across West Hyderabad.

Here are three key variables I'm trying to model before putting down a booking amount:

Pre-EMI vs. Full EMI Cashflows:Taking a pre-EMI scheme on a 2029–2030 handover tower keeps monthly outgo low for now, but if delays hit or tech job growth slows down, holding costs scale up quickly.

Land Floor Price vs Residential Yields: Does a ₹100Cr+ land auction floor actually protect apartment resale values, or will ~3.5% gross rental yield limit capital appreciation post-handover?

Supply vs Absorption Timeline:With thousands of 3BHK and 4BHK units coming up simultaneously in Neopolis, will the rental market take 2-3 years post-possession to stabilize?

Is anyone else running quantitative models or tracking price trends in Neopolis right now? How are you guys factoring in construction delays against holding costs in your calculations?
