Which place in Noida can i get better resale property value after 3 years. my budget is 20 lack rs.?

You need to keep in mind that the property you intend to buy id suiting your requirements. A lot of personal factors go into buying a property. Is the location close to your work place? Is it close to your children school? How has the area developed in the past and what are the facilities available to counter day to day needs. Based on your personal requirement you may purchase appropriate property. From what we can suggest is that sector 120 has been much talked about as it has already existing metro. Sector 77/78 has metro proposed but not existing. Development will be faster where you already have infrastructure in place. You have to do your due diligence on the project to find out about permissions and other legalities. Resale properties are usually more expensive. It depends on the urgency of your need. There are many projects in sector 120 which are upcoming. They are Amrapali Zodiac, RG Residency apart from Prateek Laurel. We cannot comment on the safety at this point of time as it all depends on the future development. Noida Expressway is any day better as for the connectivity is concerned.
