Not OP, but I've been happily working 100% remotely for almost 4 years, so I'll share my two cents. Personally, I get a lot more work done from home than I ever did at an office. Offices have lots of distractions, and it's way too easy to waste time chatting up the person sitting next to you. (That might just be me, though; I'm pretty chatty.) Cutting out the commute is a big one as well, not just for the time saved but also money (gas and car depreciation) and mental energy (I found driving 45 minutes each way pretty draining). Plus, I have the flexibility to take a break and walk the dog, or run a quick errand, or play video games—things that wouldn't be feasible in an office.
That said, there are distractions at home, too, and you have to have a lot of discipline. I got almost nothing done in my first couple months of remote work, and it took me close to a year to get into the flow and develop a structure that actually felt productive. (And then I had the opposite problem of working too much because it's harder to draw a line between work and play.) I do miss the coworker comradery sometimes, but my wife and I also have a pretty big group of close friends that live nearby, so I get to socialize with people outside of work fairly often.
Working remotely is definitely not for everyone, but you would have to pay me a LOT of money to convince me to commute to an office every day.
