David Horsley Imagine two hypothetical houses on two different streets in the same neighborhood. Call them the Green house and the Blue house. Let's watch them for 20 years and see what happens. The original owner of the Green house dies and wills it to a daughter who turns the house into rental property. The people who own the Blue house sell it to a man who owns other rental property in town.
Renters move into both houses.
One day the Green house renters lock themselves out of the house and have to destroy a screen to get in. The owner replaces the screen and adds the cost to the rent. The Blue house renters also lock themselves out, except they don't tell the landlord they had to tear up a screen and, since the owner seldom comes around, the screen stays broken. The Green renters own two cars. This being an older neighborhood, the driveway is narrow, and it's a hassle to park.
