Shawn Paris has spent the last 4 years of his life essentially homeless. He has stayed with around 200 couchsurfing hosts in the US, France and Japan while going around and performing. I hosted him for a few days and we ended up talking about the benefits of living like this. I had done something similar in 2017 and although I got sick of it after a year, it definitely had its benefits. 

It is definitely possible to save rent money or money on a mortgage and spend that on travel instead.
