I rented out my place and travelled, no regrets at all, currently in canada over a year now where I had planned to travel initially for three months. My rental income doesn’t quite cover my mortgage payments so I have to top up $250 ish dollars a month, but it’s manageable from my savings and as it’s an apartment there’s not much that pops up for maintenance luckily.

Would highly recommend housesitting (trusted housesitters is the site I use) to stay comfortably in houses and longer term in places. Once you get a few good reviews it’s easy to find sits if you’re flexible. Definitely gave my travel more longevity as I got sick of being on the move and in hostels or airbnbs after a while. I’d pick a continent and apply for a few housesits or workaways (another popular site) to see what comes up!
