Noida rental yields: what's the actual truth?

Is the supposed 30-40% rent jump in Noida actually translating to good rental yields for landlords? I'm seeing 2BHKs in Sector 137 hitting 20-22k, and Noida Extension around 15-18k. My main concern is, will these rents stabilise, or can we expect this climb to continue, especially with Jewar Airport impact? Honestly, I work in real estate but for my own investment, I need real ground truth. Also, how much are broker charges eating into this? Can you still find tenants directly, or are brokers gatekeeping every decent listing? What's the actual net yield people are seeing after all deductions?
