Well, I think it's pretty unlikely you'll end up with much of a number for community on only 5 acres, and 5 acres with a house in any habitable/comfortable area of the states you listed is likely to be far more expensive than your stated budget. Part of why we left the PNW was because we couldn't step foot on .5 acre of arable land within an hour's drive of a vegetable market (read as: town of 20,000 or more), much less one with anything that could be described as a house on it, for less than a quarter of a million dollars.
So we moved to Maine. Yeah, this winter sucked (and still sucks, from the 8" of snow they're saying we'll get Saturday, but it'll be spring snow and melt fast). There are some rednecks (so aren't there in WA and OR, too, believe you me I grew up with them!!) There's a lot of ulcer-inducing retirees with an abhorrent "I got mine, Jack!" mentality that makes me want to kick them in their brittle old shins. On the flipside, there'll be a heck of a population attrition here in the next decade or so and I'm making it my personal mission to stack the demographic deck (easier to do in Maine, with only 1 million people - a couple of tens of thousands of permies could make a hell of a noise on the state level here) so that when all the old farts are dead, we'll inherit the state.
There are also ZERO - read it Z-E-R-O building restrictions in our town. I'm considering buying a .5 acre vacant lot on Main St for about 25K and hosting a Poosh
project to build a tight row of shopfronts and apartments out of
cob & strawbale with
perennial gardens and a
workshop behind - the Live/Work Cluster pattern from A Pattern Language. It's perfectly legal for me to build that, by hand, with mud, passive
solar, composting toilets, the whole nine yards. The most restrictive rule is about residential zoning in the outlying areas of town, and the rule there is that you CAN have a business in your home, as long as it's not one that needs a sign. We were actually told "no sign, no problem." We're right on the coast within farmers-market distance of several good sized towns and the state's largest
city, and only a few miles from both the Good Life Center in Brooksville and the Common Ground Education Center in Unity.
A sampling of land/houses within a 20-minute walk of where I now sit: a 14-acres-of-pasture organically managed farm with 4br stone farmhouse with beehive
oven, 6 fireplaces, and a barn as big as a city block for $215k; over 100 acres of mature tamarack & cedar forest for $103k with a driveway and a Quonset hut; 60 acres of mature woods for $51k on a dirt road with a dug well but no driveway. 205 acres of mature woods with a GORGEOUS creek through the middle of it for 80K..... Good luck finding that much land at those prices anywhere west of the Rockies - and the best part out here is that you won't go to jail for collecting rain
water!
