Is 'High Rental Yield' corridor just infrastructure hype?

Okay, I'll be honest — I'm completely fed up of renting. Landlord ne phir rent badha diya, it's just not worth it anymore. Everyone glorifies the 'High Rental Yield' corridor for investment, but is it really just infrastructure ka magic? I'm talking about the new metro lines and expressways. Prices wahan pe bohot badhe hain, but is that appreciation sustainable, ya bas hype hai? Which specific pockets within 'High Rental Yield' do you guys think actually benefited the most from all this infra development? Or is it all just speculation now? Change my mind.
