I'm just middle class that has started that ball rolling up hill.
I will be close to broke when this thing is done. I will be lucky to have 10 grand in the bank to hold on to until I sell this one and build the next one.
I just have to manage our money well. I buy used when I can, pay cash for things, and trade out work for work. Heck I bought most of my kids Christmas gifts sceond hand a used gamecube in good condition is just as good as a new one to a kid.

The yard would have been 15,000 but I had been building and repairing computers for free for a friend of mine who happen to own a landscape company I did not know about. Then one day when I was helping him I told him what kind of yard I needed and he told me he could do it for 5300 not 15,000!
So again, little money on the build bigger money on the sale then roll it and buy stuff for cash in between builds. I paid cash for my kids braces, paid cash for our bedroom furniture, and with cash people will bargain that stuff way down. Oh damn I'm way over into bores-ville.
