Yes the rent would increase but I am not saying to follow this approach for life but you can stick to this approach at least for next five years and then my understanding is supply and other factor would bring the prices to more affordable level. If you compare the rent of residential properties in India they haven't grown like the cost of these properties.
I agree with the argument raised here that property prices can not correct over night but the problem is technical otherwise it wouldn't take time to fall. Property prices are not available on any exchange, ownership transfer is not that easy. Moreover it's the local brokers and builders who can change the dynamics of any property market. There are many transactions done where there is no ownership transfer (Registration) only a power of attorney is taken. The sole purpose of these transaction is to hike the prices and those parties are traders.
