For me; my main concern would be child education. But at my childrens ages (4&7) I believe I could educate them enough to keep them up with required standards. At least until senior/high school. (11+) From then onwards I believe my children would need specialist/trained education which is above me.
My only other concern would be money. Like you I could rent my house out to cover mortgage and give me some spending + YouTube monies means I would be able to travel on a budget.
I am jealous and would love to have the balls to do it. I have other issues that would restrict me for taking the same leap. Credit Card/Loan debts and Pets (I have 2 dogs/ 1 cat/ 2 fish!)
Maybe I can live my dream through your videos/channel.
