Don't know what's the status of properties in south and north east but in North only viable solution is to buy land in hill station and it's for only retirement purposes.
Down south in metro cities we can get 800sq.ft flat can be bought starting from 80 lakhs but if it's in premium location sky is the limit, I even saw a price tag of 5cr for a 3BHK flat in the middle of the city and yeah it's around 10 years old one so who knows how much the cost will be for a villa.

The problem with housing and its price is rising and there is no control over it.
We have to make sure we get a house once in our lifetime and rent it as well. Renting is often a good source of making the money back. But this will be difficult for some most types of work cultured people.
The housing bubble will collapse at one time, but how, I cant say.
It's overdue but the value is holding up because of the black money that is used to buy these real estates whenever it is available for sale and they can easily tackled this from IT by reporting a very low price in the documentation to save the registration charges as well but to utilize all the unaccounted money. I am sure this can be tracked and hunt down but one who are doing it is also in the power to shut them down so it will never happen.
