Mohali 3BHK: Remote buying dilemma

Spent weeks researching options in Mohali's 'Ready to Move' corridor, but it's tough being in Dubai. I'm looking for a 3BHK, budget around ₹1.2 Cr, maybe up to ₹1.5 Cr. Projects like Marbella Grand and Highland Park in sectors like 90/91 keep coming up. Are these truly the best deals for rental yield and appreciation? I can't do a site inspection myself, so ground truth from residents is crucial. Also, any recommendations for reliable property managers or legal help for remote buying with a POA? Honestly not sure which project offers the best overall value right now.
