Ghaziabad home search: Ready vs UC dilemma

Ghaziabad mein property search itna tough tha, I swear. Jab apni flat li, tab Ansal Neel Padam Kunj dekha tha but under-construction projects se darr lagta tha. M R Homes Heritage Tower ka bhi option tha, builder ka track record sunke thoda hesitate kiya. Ready-to-move hi prefer kiya, OC milne mein kitna time lagta hai, pata nahi. Jo log Ansal Neel Padam Kunj mein rehte hain, batao yaar, possession ke time koi hidden costs lage kya? Builder ne sab promises poore kiye ya nahi? Maintenance charges ka kya scene hai wahan?
