First home hunt: Omaxe, Sector 18D, and cold feet

Sector 18D mein ek 2BHK flat dekh raha tha, Omaxe ka project. Honestly, first-time buyer hoon, samajh nahi aa raha kaha se shuru karoon. Parents bolte hain sirf location mat dekho, builder ka track record bhi check karo. RERA news mein Omaxe ki delay wali baat padhi, toh thoda nervous ho gaya. Kya sirf location enough hai ya builder ki delivery history zyada important hai? Koi tips dega shortlisting ke liye, especially for a budget around ₹75L? Kahan se begin karoon?
