Investors House: The real ROI picture in Ghaziabad

Budget finalised for an investment property, loan pre-approved. Looking at Investors House, Ghaziabad, ₹55-70L range. I'm in real estate, so I know the marketing, but what's the *actual* capital appreciation track record? What realistic rental yield can I expect, post-tax? Honestly worried about resale liquidity later. Is there an active secondary market, ya fir exit strategy mushkil hogi? What's the community's take on its long-term ROI potential?
