Homer's job, as depicted, would pay a lot more than 25k. The article is based off a single frame of the show like 25 years ago. The writers/animators likely didn't mean to establish his cannon salary.
No way that sort of union job would pay under 50k no matter where you lived.
- it's not exactly in Springfield
+ it's new construction
- it's just under 2000sf
+ at $165k it's probably a lower payment than a mortgage on $100k in the 90s
...in the NE and west coasts. This isn't out of the ordinary in large cities like Houston, Atlanta, Dallas, Phoenix, etc.
If you limit your search to Top 10 MSAs by population, you'll see that roughly half are expensive and the other half are not. More people live in Atlanta metro than SF, Seattle, or Boston metros but housing costs are fractional vs those places. (Salaries are not equivalent to SF, but IIRC most SF companies pay ~80%+ of SF pay. 80% of SF pay is "mansion money" in most US cities.)
