Sawang Daen Din
Sawang Daen Din is 'almost' the midway point on the highway (22) between Sakon Nakhon and Udon Thani.
59 km to Udon and 80 km to the city (Muang) Sakon Nakhon.
It's a town that has been growing in recent years and has a TESCO store.
There is plenty of through traffic in the town.
The highway leads to Nakhon Phanom which has a border crossing into Laos.
Think highway 22 is part of a planned Asian International Highway system.
Besides being a refueling and rest stop when traveling between Udon and Sakon Nakhon, the town is popular for its BBQ free range chickens. Whenever I travel through the town with my Thai friends, they always load up with the ready to eat chicken.
I did notice a small ex-pat community in the area. Most foreigners live in nearby villages and do their shopping there.
As for continuing to work in Thailand at your current profession in real estate, put that right out of your head. You could do such a job in a major metropolitan area, but not Sawang Daen Din.
Job prospects for foreigners in Thailand are very limited with plenty of requirements and restrictions. Check out Thai immigration website for work permit rules.
If you're looking to keep busy, consider teaching English. It's not a high paying job, especially here in Isaan. Average 20,000 baht, but it gives you something to do. It's a great means of meeting many people in the community.
Keep in mind any work you do will require a work permit
