Bank-funded projects have too many hidden catches.

Bank-funded projects in New Chandigarh feel like a big risk right now. I'm finally done with renting, looking at a 3BHK around ₹90L in New Chandigarh. Builders push construction-linked plans with bank tie-ups, but I'm worried about EMIs starting on unfinished flats if there are delays. Self-funding more upfront seems safer, tbh. What's the actual catch with these bank schemes? Should I just avoid them?
