I'm not that rural. The price for the electric run is $350 for new poles and the service is about $0.10 p/kwh. I'm fine with adding solar. I simply don't have the money right now. And I am not getting a mortgage as the 'just add it to your mortgage' attitude is what has lead to so many (non protested) price hikes in the first place.
So adding 'just another' $10k to the price means I get to wait so many extra months to save money before I can even build.
I don't know how standard a mortgage was 30+ years ago. I do know the interest rates were higher and they weren't handed out like candy as they are now. My grandfather bought a brand new house in 1972 for $12,000, paid cash. And my parents built their first house in 1990 and paid cash as well. They moved and built several other houses all with cash as well. Is it too much to ask that I be able to pay cash for a not so great but brand new mobile home?
