Allure Floors Four: Maintenance charges are always a rip-off.

After 7 years of renting, I'm finally taking the plunge. Landlord just raised rent again, so the EMI vs rent math is clear. Looking at Allure Floors Four by Allure Constructions in Mohali. Heard mixed things. What's the construction quality like after possession? Any issues with plaster or seepage? Also, their customer support after booking – do they actually respond? And what about post-possession maintenance charges? Are they reasonable or crazy? Trying to avoid surprises. Any insights from current residents?
