Ghaziabad builders: what you see isn't what you get

Since January I've been shortlisting flats in Ghaziabad, especially around Raj Nagar Extension aur Siddhartha Vihar. I work in real estate, but buying for myself is different, you know? My budget is around ₹75-95L for a 3BHK. Gaurs, ATS, aur Mahagun ke projects dekh raha hoon. Marketing toh sabki top-notch hai, but real picture kya hai delivery timelines ki? Kaafi builders bolte kuch hain, karte kuch aur hain. Aur construction quality? Suna hai Gaurs mein finishing issues aate hain kabhi-kabhi. But honestly, hidden charges ka sabse zyada darr lagta hai. PLC, EDC, maintenance deposits – yeh sab possession ke time pe kitna hit karte hain? Kya koi builder in sab mein thoda transparent hai? Any advice on which one is better for an end-user?
