I thought I was the only one in my family interested in Mustachianism (hence my name -- also relates to the fact that I'm an almost-vegan and most of my family are meat eaters), but just today I discovered that my great-grandfather's financial life involved some degree of badassity. (I suppose most people who lived through the Depression were/are totally badass Mustachians, but it's neat to see it written down in black and white.)
The file is too large to attach here, but it's a hand-written list of his debts, what he spent on various aspects of homeownership, etc. and how long it took him to pay them off. The total cost of the house, including interest, etc. was $6675.25. He bought it during the Depression (thanks to a loan from his brother) just after he got married and had a low-paying job, and he paid it off in 12 years. He was one of 13 children born to Czech immigrants, so he had to start from the bottom and work his way up.
The best part is his celebration at the bottom of the calculations, where he wrote: "Paid Up In Full. Don't owe one cent to nobody up to this date except $150 in taxes. Thank God!"
