Saheel Hinjewadi Phase 3: What's the actual ROI story?

Did a site visit to Saheel Code Name Hinjewadi Phase 3 last Saturday. Brochure looks good, but I'm looking at it purely from an investment lens for a 3BHK. What's the real rental yield people are seeing there? And the capital appreciation? I'm already in a 2BHK, thinking of this for long-term wealth. Is the resale market liquid enough, or will I be stuck? Any idea about the investor vs. end-user ratio? Don't want a ghost society. Real experiences needed before I commit.
