End of week three:
Finally put in some lighting, windows, and upgraded counters. Not using any aspiration rewards. Aging on. Can't help but wonder if I can make it.
Looks like lot value is just starting to go up. I'm gonna push this challenge a little further and see if I can achieve it without ever expanding my little 8x8 hovel.
