@hallie4 You can get a really decent flat for 1.25-1.5cr 2bhk in a premium location(delhi) however if you guys want to move towards 3bhk I would recommend that you should go for NCR location as they usually give you better option in your range.
@hallie4 No instead use the 2.5cr and buy various rental properties at prime locations so u can rent them out or turn them into hostels, that way u earn more in just a few years and your 2.5 cr home would be affordable even without taking loan
