I've been looking [obsessively] at Washington (state) lately, particularly in the Puget Sound area. There are many [declining] lumber/fishing towns (Aberdeen, Centralia, Bremerton), where dilapidated houses can be had for $20,000 paying $400/year in RE taxes. A decent house (nonfixer) can be had for $50,000/$600 and a large one for $75,000/$800. In short, housing can be ridiculously cheap. The crime stats are kinda iffy but not as bad as Chicago.vivacious wrote: I would posit many small, west coast places as fairly good for ERE. Specifically within an hour or 2 from a city. The prices are MUCH lower at that point. You could go into the main city sometimes also.
If you don't mind the tsunami bottleneck risk, then Ocean Shores was/is a developed retirement community where 4 season vacation homes can be had for around $110,000/$1200 or so.
Artsy/touristy places like Port Townsend and Anacortes start around $150,000/$1600 or so (lowest I've seen was around $60k but that didn't look too good). That's what I'm looking at, namely for the added entertainment value. I've also looked at Union, WA. Bill Gates has a house there. That's about as far away as you can get from anything in Puget Sound.
There are also rural opportunities. You can get 10a for $175,000 with a small house in the middle of nowhere.
TL;DR - Washington state is currently my favorite state due to: decent RE prices, low RE taxes, no income tax, no excessive winter heating costs, long growth season, fresh water from the sky, lots of nature.
