Looking To Start Wholesaling From Afar (Any traveling spouses out there?)

Hey there! I'm new to the REI space and I'm looking to start investing in Baltimore. I've chosen wholesaling as my first approach since I don't have a ton of capital up front to do a BRRRR or flip. I'm currently traveling abroad since my spouse is in the foreign service, so I'm looking to do this from afar.

I lived in Baltimore before recently moving abroad, so I know the landscape of the city a good bit. I'm looking for any advice you all might have on how to talk to sellers from afar and how to navigate showing buyers the house. Do people ask their friends to go? Use realtors? 

Also, any connections from the Baltimore area or traveling spouses would be greatly appreciated! Thanks you guys!
