Or any advice on the best way to manage from a distance?

Any amenities can help you, so be aware of them and telling about anything that is in a walking distance as well as the school district that is involved,  Know about where the nearest bus stop is, any parks, highway access, and lakes nearby.  

I have looked at other states to invest in but then crops in fear since we have never done this before and would have to do it long distance.

You could go 10 miles outside of our location to areas like Reeds Spring, Rockaway Beach, and even Lampe and be astonished at the immediate drop in interest just due to the slightly further distance.

Being a property manager myself, distance is an issue for me.

Be careful, though, many times these would be excellent tenants and the time and long distance call expense of checking them out could pay big dividends.7.

But like others said even moving these a short distance will cost 5k.

I don't think it can be profitably done long-distance unless you have relatives there to help. 

I'll have to see the beam distance when I get to the house!

With proximity to TG the "street to street" fact is less of an issue, but as you get a certain distance away from the park that becomes true, certainly.As you go farther south rents decrease and you'll find tenants who work minimum wage jobs and are trying to get established, more blue collar workers, etc.
