New DS Apartment ROI seems optimistic

₹70 lakh for a 1BHK in New DS Apartment – I'm honestly struggling with the numbers. I work in real estate but buying for myself is different, and I can't shake off the feeling that the projected capital appreciation for this ongoing project feels a bit too optimistic. Are we seeing any real price movement post-launch, or is it mostly just brochure inflation? What's the actual rental yield expectation here? Off the record, what are people actually getting per month for similar units nearby? And honestly, the builder's delivery track record... is it just me or are they always a bit behind? I don't want my capital stuck in an under-construction project for years. How liquid is the secondary market for something like this after 5 years? Is there a buyer base beyond first-time buyers for resale?
