This is how I like to manage my 100% remote position -- I rent a small space to convert into an office, or just hop into a coworking space depending on the amount of time I'm going to be somewhere and the infrastructure that needs to be built out.
I have worked "from home" for years and have much better mental health (and therefore better relationships) if I have a separate space to work from.
I now have a quiet, private space to work, and a nice 5-6 minute bicycle commute :D
It costs a little bit (~$300/mo for the space & utilities - yay for small-town-Ohio pricing), but it's totally worth it.
