First check the credibility of the builder. Their experience counts a lot.. Find other properties by the builder and try asking the residents there about how is the quality and maintenance. Then the location. How close is it to basic requirements of daily living. Super markets, chemists, hospital, school, airport or railway station etc. Also the location should be feasible and have good land value. Then of course what the property offers you. The rooms, lofts, fixtures, paintwork and plugs. Buying a home is a one time huge investment. There is nothing wrong in thinking ten times and then going ahead with it !
