Back in 1970, I worked in NJ but lived in the Pocono Mountains of PA. I just couldn't afford the cost of living in NJ at the time and endured a 2 hour commute each way. In 1979, I was living in a trailer when a friend introduced me to a farmer who had just subdivided some land. It was a beautiful piece of property on a hilltop with a great view. He offered me the entire 25 acre, 7 lot subdivision for $25K. That was way more than I could afford back then so I bought a single 6 acre lot instead.
I moved my trailer to the lot and made plans to build a house. I used the value of the land to get a construction loan and began building, using my own labor. Over the next 10 years, I used the accrued sweat equity to borrow $$ to buy additional lots. A few were from the original farmer / subdivider and some from other land owners who had purchased from him. By 1990, I managed to buy all of the original 7 lot, 25 acre subdivision. It cost me $120K to buy what I could have had for $25K just 11 years earlier! It's amazing what can happen over time.
