Personally, if it was me, I would not go near this home regardless of the beauty or deal. you know the habit of termites. They have their home in the ground and build tunnels to the wood because they hate the sunlight. Once a home has to be tented, it really has been infested into the actual home and structure.
What a night mare.
Tenting has been going on for a long time. I once lived in an apartment when I was young that had to be tented. they strung up this huge tent thing and told us to be out of the apartment for three days.
When we came back, there was hardly a smell of any chemicals. And I am still alive and kicking. So, the danger or health danger is really not a concern, but I would be cautious with the very young and the old, and those with respiratory problems.
