Also to help you if you cannot afford a 2BHK at regular prices, you can look for group buying of property also.
This might be helpful because the prices are much lower when you group buy something rather individually. :)
No rajeev, Puspanarayan is a 2-3 BHK project in panvel mumbai, so there are no 1 BHK there in so if u want to buy a flat in this locality you will have to increase your requirement to 2 Bhk atleast :)
