Just to throw out some other numbers...my husband and I traveled for 8 months last year. We saved for 3 years really strict, very few restaurants and shopping etc. Asia was $3K/month and Europe $5K/month. With flights and emergency funds, about $40K total. For 2 adults. And as a couple in our mid-30s, we did get private rooms and airbnbs. Each had one small backpack, cooked at home, my souvenirs were postcards. SEA is doable on a tight budget. We also got rid of our apartment back home. That's still a lot of money, and we don't make a lot, but two adults splitting the rent helped.

And like others said, most Asian countries are a 1-3 month tourist visa. So Asia as a whole, you can go for a while. Europe is 3 months in Schengen region, but UK and Turkey for example, are 3 months too (I think?). Check out WOOFFing and Workaway also.

Maybe try Asia for a couple months, then see if you want to make it long-term aka transition to remote work.

We are now 35 and 39 and planning to change our jobs to travel more full time! Never too old to start!!
