Noida Extension: 'Affordable Homes' mein buying ka sahi time kya hai?

The 'Affordable Homes' segment in Noida Extension feels a bit overvalued now. I'm in a 2BHK in Sector 143, eyeing a 3BHK there. Last 1-2 saal mein prices kaafi badhe hain kya? Is it worth buying now ya wait karna chahiye? Already home loan hai, so EMI jump ka tension hai. Ground reality kya hai?
