I don't mean to be condescending, but the only "telling" thing about that is your inexperience. If you already know it's a place you couldn't stand to live, it's an extremely bad idea to move there. Do not second-guess yourself like this! You will end up regretting it.

Telecommuting is not for everyone, but being new to the industry, your perspective is likely to change over the next few years if you stick around. I'm not saying it'll reverse -- you may find that your first impression was right -- but your point of view will be altered by your experiences, and without those experiences to draw on, you cannot expect to have a well-formed impression of this arrangement.

Not liking working at home is not a good reason to move to a place where you won't like going outside.

This is incredibly true. Though, the main thing keeping me in line right now, is that I'm just over a year away from moving to where I really want to be- Seattle!

Once I'm there, I don't know what I'm gonna do. Probably program at a cafe every day.

When you get to Seattle, check out Office Nomads in Capitol Hill. Sounds like you will find lots of like-minded people there.

You might want to look into coworking spaces where people that are not working for the same company, such as freelancers or remote workers, share an office.

Where might I look for something like this? Is there a centralized location, or is this the sort of thing that people just kinda find on Craigslist or something?

Google search, that is how I found some places in London. And it was really great way to go, and some where very cheap. £50 a month!

You don't have to work from home, depending on where you live you can find coworking spaces from where you can telecommute instead. Maybe the company can even help with the coworking space costs, if you make it clear that it's a much better option for you than moving.
