Enable the move_objects on code. Buy a house and sell pieces out of the road and sidewalk. You can also turn it to gravel or fade the lines. Next, build dry wall. You can also try building a second floor. Have holes in the floors on first and second levels. Have part of the wall bare with no wallpaper. Have non-matching windows (any window other than single pane fixed for the primary and single pane fixed for replacements recommended to simulate replaced windows). This also applies with doors. Let the trash overflow. Make sure to have plants that require water so that they can die. When things break, do not fix them. Do not clean the toilet, shower, fish tank, etc. Note: This is not a good home for Sims.
