Housing and food are expensive in Seattle, as well as the surrounding area. Gas is expensive. Insurance is expensive. PARKING is extremely expensive. If you want to keep your costs low, you will want to rely on public transportation to get to/from work. Living somewhere within walking distance of a light rail station may be do-able, or somewhere that is close to one of the “commuter” bus routes.
Make a spreadsheet of different potential locations and the estimated time it takes to get to your new job. Decide whether the time/money offset is worth it for you. If I was going to move somewhere new, that is what I would do. It’s always time or money.
