V S SVS KSN Residency

Honestly, I'm so fed up of renting and finally taking the plunge to buy. I'm looking at V S SVS KSN Residency in Ghaziabad for investment. Builders always promise big capital appreciation, but what's the *actual* reality there? I'm digging into V S SVS Constructions' delivery track record, as delays kill ROI. What's the real rental yield folks are seeing? Don't want my capital stuck.
