I own rental properties mostly in Tampa, but Lakeland is also an area with significant growth potential, given its walkable downtown, location between the hubs of Tampa and Orlando, colleges and presence of large employment centers, such as the Publix headquarters.

I chose Atlanta because it is the international transportation hub of the south east having the busiest airport in USIt has a diverse economy with many Fortune 500 companies setting up offices therefriends and family that moved down theremet some investors that were from NY that invested down theregood size populationaverage salary is high enough to pay me rent and rent is decent enough for me to make a profitprice it is way cheaper than NYC

HUB City REIA is loaded with people who invest there.
