BTW
My son is also about to retire from the Navy in a couple of years & is considering the same thing in Omaha. He is stationed at Offutt AFB in the Naval Security detachment.
Also TREC (Texas Real Estate Commision), while tough, has an avenue to get a license. There are a couple of schools here that offer all the classes and ride-alongs to meet the requirements. Champion School of Real Estate is one.
Good luck!
I have found a lot of good training available from InterNACHI online. It is free to all and will tell you quickly if HI is a fit for you at little to no cost. I have been a member for several years. InterNACHI is the largest HI organization and offer lots of resources for training.
Just Google InterNACHI.
