The most important factor in determining an area to invest in is to assess the job market for the area. Is there a major employer that will provide the majority of the jobs for the area, also known as Core Jobs? What is the average wage for this employer? How many people will be employed by them? Are they hiring or laying off? Is it a cyclical industry?
With Core Jobs, you also have Non-Core Jobs, in other words, jobs that support the community formed from the Core Jobs. Examples are restaurants, car dealers, hair care, etc.
Where will you get the majority of your tenants from, Core or Non-Core Jobs?
