I have not seen your youtube, though I wanted to comment.
Dear hubby and I built a house from the inside as the structure was on the
land we bought. It was just a shell.
That was in 2013. This might have taken us about 3 years.
We bought supplies finished those then went back home to buy more supplies.
While this might not have been the easiest
project we have taken on ... it was rewarding. At least on my part.
We love living here so I feel buying this property was the best thing we have accomplished in our life together.
