Check the demographics for the area you are thinking of purchasing in to see what would be the most suitable tenants for the properties provided. Eg lots of units with surrounding eateries. What is the average age of the population? Are there many primary and secondary schools to choose from? What is the transport like for entertainment or higher education?
Choosing your ideal tenant can help you choose the property which is right for them, this can help you gain longer term tenants as the location is also keeping them happy.
