How in the Hank did all the guys end up living next to each other ?

Hank , Bill , Dale and Boomhauer have been friends from a very early age . They were friends at school and even hung out together outside of school .

Even though they are known to be dedicated friends , it still seems to be very rare to end up living side by side .

Does the show ever address how they all came to live side by side ?

Who first lived in the neighborhood ?

In which order did the others arrive ?
