My wife and I bought a 10 acre (~4 hectare) piece of land in very rural, very Northeastern US for 30k USD. We paid for half with about 50% of a year’s combined income, and half with money from when my wife’s parents sold the family farm. Land came with a derelict house, but it turned out to be in better shape than initially thought. Place is fully off-grid: no water supply, electricity, or plumbing. We are living in a yurt while we, my wife’s dad who is a carpenter, and some (paid) timber framer friends make the house safe to live in. Currently we pay about 5% of our combined yearly income in property tax, but that will likely go up when the house is done.
I don’t think so. My parents --especially my mom-- were very good about teaching me to respect all life. We were always allowed to kill mosquitoes, though: second most deadly animal on Earth after humans. Still never tried to cause them extra pain.
