10 years of renting, finally pulling the trigger

Two years ago I'd have laughed at these prices, but after my landlord raised rent again, I'm seriously looking to buy. ZEN & SATO (UPCOMING) is on my radar. Price is ₹2.98 Cr–₹4.13 Cr. It's under construction, making me nervous. What's the real capital appreciation been like for similar projects post-launch in Bangalore? I'm trying to factor in actual rental yield for my EMI vs rent math. What are people seeing? Also, any insights on the builder's delivery track record? Are they known for delays? Worried about getting stuck if it's mostly investors. What's the resale potential like in 5-7 years for a project like this? Trying to understand the true ROI.
