Empty nest, new plans, Ghaziabad rental doubts

₹25,000 for a 2BHK in Crossings Republik — is this rental yield actually good for landlords now? My kids have moved out, so we're planning to sell our big house and get a smaller 2BHK there, maybe for ₹70-80 lakh. Pehle lagta tha rent se achhi income ho jaati hai, but with property prices up, I'm not sure. Rent bhi toh 30-40% badh gaya hai last 2 saal mein. Kya yeh justified hai ya market overvalued ho raha hai? Is it still worth buying property in Ghaziabad just for rental income? Or should we just buy for our own use? Any landlords here, share your experience please. What's the real ROI post maintenance and taxes?
