You can have home, land, and installation of home on land for about 25K, if you're willing to settle for small values of each. Ebay has cheap land in rural places. You can buy a new manufactured home for less than 20K: https://www.factoryexpomobilehomes.com/micro.asp . You can get ten years' supply of basic food for probably $3000, depending on exactly what you get, from Costco: http://www.costco.com/emergency-kits-supplies.html . After property taxes and septic installation and other miscellaneous niceties, if you round up to 36K, that's basically $250 a month that you'd need to clear after taxes.

Edit: for 10 years; I'm assuming you'll have to replace such a cheap home after 10 years, but if not, the amortized cost is considerably lower.
