Ghaziabad investors: what's your take on long-term maintenance?

Okay I'll be honest, the long-term maintenance costs in Ghaziabad projects are a big concern for me as an investor. I've seen this pattern before where charges escalate quickly, hurting rental yields. For Amrapali Vaishali, what's the ground reality on maintenance vs. actual service quality? Are the security systems really effective, or just for show? Does it justify the charges? I'm trying to calculate a fair ROI here.
