My Delhi investment from Dubai: Ground reality needed

Budget finalised, loan pre-approved – ab Maitri Apartments ka soch raha hoon. I'm based in Dubai, so site inspection mushkil hai. Looking for an investment property in Delhi, concerned about long-term tenant attraction. Wahan security systems kaise hain? CCTV coverage, visitor management, guards ki reliability? Kya power backup pura flat ke liye milta hai, ya sirf common areas? Tenant attraction ke liye yeh sab matters a lot. Kya these things affect future resale value aur maintenance costs? Koi owner wahan ka experience share kar sakta hai? Need ground truth.
