Are Sector 37 hidden costs killing NRI investment ROI?

I'm based in Dubai and honestly, my Sector 37 investment isn't looking great. The agent talked up amazing rental yields, but now I'm seeing all these hidden costs. Maintenance charges, unexpected RWA fees, even property manager costs are way higher than quoted. It's eating into the supposed appreciation. Is this common for Chandigarh? For other NRI investors, how do you manage these unexpected expenses from afar? Did you factor in these hidden costs? Feeling really frustrated trying to get a clear picture.
