The military is growing and migrating west bringing more jobs, New Bio Tech hub is being built in Downtown, Apple buying in Rancho Bernardo, the Chula Vista bay front Development, Amazon HQ, etc.

Memphis is quite different from both of these according to the posts I've seen.Phoenix is having a surge of "in-migration" of people from California, Seattle, and Denver. 

You can use census or USPS data to track migration. 

Migration to the area and the population boom in the valley hasn't stopped and there is no indication it will any time soon. 

You may want to look at a net migration chart for TN by county.

@Hunter Terryn not only do those factors present a real opportunity to grow appreciation, unlike other growing Southern cities, Birmingham has the housing already in place to support a net influx of migration.

I migrated my fix and flip operation and property management into workspaces designed to handle all.

Look at migration flows, 2022 had California show the largest migration outflow in the entire country as 328,000 people left the state.

A state like TN is growing because people are migrating from high tax states, such as my state of CT who’s economy is on life support mostly due to those same tax and spend policies and politicians I mentioned above.
