I just leased some land and I am buying a 3d printer to build a house! 100" one. I can only afford to buy a small plot if land and I think I can get about 25 3d printed houses on it. I am if the opinion that it will be worth it once I am done. I can buy upto 48 houses before I max out the land but I think I would rather have the cash and move houses out to other plots of land, depends on what my neighbor wants to do. Just get a loan for 10k and you can also own a 3d printer today.
