Location is Everything
Almost everything can be fixed, but the location, the location, the location cannot be fixed. Buy location, NOT price.
Besides common factors such as traffic connection, security, neighborhood, distance to the nearest hospital, and infrastructures such as supermarkets, shops, and restaurants, it is important to verify the connection to basic public services. That is water, telephone, internet, electricity, and garbage collection. Which are the available providers and how reliable are their services? Are there any (regular) interruptions or connectivity problems with one of the basic services in the sector? Does the availability of one of these services vary according to the season (rainy season/dry season)?
