Hi, I'm from the Keene area and I'd 2nd the suggestion at looking at Alstead if you want to be around other principled libertarians and voluntaryists and get some cheap land to live off for farming (I'm not a farmer mind you). There are lots of people up in Alstead and south of Alstead (20-25 min or so) is Keene, NH. Keene is the biggest "city" nearby with lots of shops and things. Alstead has a gun shop and a BBQ place and a laundry matte. I think there is one other bigger employer in Alstead. There is also Concord and Manchester semi-nearby. Concord is like an hour 10 min from Alstead and Manchester an hour 20 min. Keene has some employment opportunities. There are insurance jobs in Keene and a company that does something with managing groceries for the north east. This is not a grocery store in Keene- but like headquarters or something. There are lots of grocery store jobs, a walmart, etc too. There is PC connection. Apparently they do something with manufacturing motherboards (? having a hard time understanding what they do cause nothing is really manufactured in the US and apparently they send the motherboards away to China to be finished). There are also a number of restaurants in Keene. We have a bunch of technical people living in Keene. Three are working directly in tech (one software developer, another does a help desk sort of job, I'm CEO of a tech company, another is a data scientist or something like that at the grocery- and I think there is another person doing something similar at that company), and we had another person who was technical whose doing help desk, and another whose done some other stuff, we have had a handful of other technical people, one technical person is running a store now, etc.
Cost of housing now.. hmm I think that depends on what you plan to rent or buy. It's probably going to be cheaper in Alstead or anywhere outside (but near) Keene. The place I bought was a 3 bedroom ranch /w two car garage. That was around $200,000 USD which basically would have gone for $350,000 in New Jersey where I'm from. With a mortgage and insurance you'd be looking at about $2,000 / month for my place. If you're looking to rent a bedroom I think people are paying in the $400-700 range possibly with all utilities included, etc. And up to $1,200 for 4 bedroom apartment/house. 1 bedroom apartment might go for $700-1000 range. 2-4 bedroom $1,000-$1,200. This is Keene mind you. I would imagine Alstead is cheaper. Keene has higher property taxes than the surrounding areas. It's the one down side to Keene. Though the up side is living in New Hampshire and around here is pretty cheap compared to many parts of the country and there are good jobs available. We have people living in Keene making $12 / hour no problem. So unlike places out in say California/New Jersey/New York/Boston/etc you don't need six figures to survive here even if we have at least some people making six figures or close to six figures.
Probably the most successful people here financially speaking have jobs they work remotely or are otherwise in business for themselves. So for instance we have a security researcher here who does well for himself, I have a company I run, I know some people who have remote jobs (helpdesk, etc), another person does computer repair (this can actually be quite lucrative and bring in $65,000 / yr which is more than adequate to live well here in NH).
I think the real question is what skills do you and your partner have? That's probably going to dictate employment opportunities. But even if you don't have much in the way of skills/education you'll probably still be able to do decently here. There are jobs that pay adequately for people who don't have much in the way of skills or education.
