Floor-rise premium and funding methods, totally confused

Spent the whole Sunday checking out options in Sector 24C. Saw a 3BHK for around ₹1.8 Cr, but the floor-rise premium for a higher floor felt steep. Is that worth it for a better view? My last investment in Mohali, a 2BHK, didn't really see a huge jump for floor preference. Also, I'm looking at a project where the builder claims it's self-funded. Does this actually give us more leverage on payment terms, or is it just marketing? I'm trying to figure out if bank-funded projects offer better security or flexibility for investors. And frankly, for a quicker ROI, should I be eyeing secondary market deals instead? I've seen some good resale options in Aerocity that seem undervalued. Can you negotiate more on those compared to new launches? Any insights from your experience would be super helpful.
