Secondary market deals are the only way to save money in Mohali

Spent the whole Sunday checking out options in Sector 31. Satkartar Homes ke kuch projects dekhe, but current pricing dekh ke lag raha hai kaafi stretch ho jayega budget. Builders to bilkul bhi negotiate nahi kar rahe, they just stick to the price list, which is frustrating. Soch raha tha ki secondary market mein deals better mil jaati hai kya? Matlab, resale mein negotiation ka scope jyada hota hai? Ya Mohali mein ab kahin bhi price correction ka scope nahi hai, especially in areas like Sector 31? Also, is floor-rise premium worth it for an end-user? Ya lower floors pe bhi same value milti hai? My budget is around 1.5 Cr for a 2/3 BHK. Honestly not sure if I'm looking at the right places, any tips on finding genuine value?
