Ansal Aastha Mig Zone: under-construction quality kaise check karein?

Honestly, buying property for myself is a whole different ball game than selling it. I'm looking at Ansal Aastha Mig Zone in Rajkot for investment, but under-construction sites pe quality check karna bahut important hai. As a broker, I know builders often gloss over things. What specific red flags for construction quality should I look for during site visits? Like, how to spot potential future seepage ya bad fitting quality beforehand? These things really hit resale value and maintenance cost toh baad mein sar dard ban jaati hai. Also, amenities ka kya scene hai? Do they actually deliver what's promised, ya just for show? Investor ke liye quality aur usable amenities hi long-term value dete hain, warna just fancy photos reh jaati hain.
