Faridabad buying: My 'insider' knowledge is confusing me

Okay, I'll be honest — I thought my industry knowledge would make buying easier, but it's just confusing me more. I'm looking at the RERA Approved Projects corridor in Faridabad for investment, not end-use. My budget allows for a 2BHK. But I'm seriously wondering if this area has already peaked. Prices feel a bit inflated, especially in sectors like 88 and 89. Are there any pockets still undervalued? I know what builders don't tell you, but off the record, is the ROI still good here? Or should I look elsewhere in Greater Faridabad? My worry is getting stuck with something that won't appreciate.
