All the exterior walls are concrete block with a brick facade, 14 inches of masonry in all. The builder of the home was the Corps of Engineers director that built the large lake a few miles away, from the look of the Corps offices and the house, I believe he purloined most of the materials and probably the labor as well. I've been here almost 20 years on a 25 year lease at 500 per month, next year I'm purchasing the 20 acres and house with the owner carrying the note and giving me a large credit on the years I've leased as a down payment, total loan should be around 150,000.
