I grew up around Guymon, my family still lives there. Back when I was a teenager and in college I worked at a feedyard, my foreman came over as an illegal in the early 70's. He eventually became a citizen and for about 20 years lived in a trailer at the feedyard, he saved up and bought rentals when I left the panhandle in 07 he had 15 rentals. Back before the hog farms one could buy houses in Guymon for $30k and in the surrounding towns for $15K. I'm guessing those 15-20 rentals are making him one hell of a retirement these days.
I'm going to be up there next week, Ill try to look him up and see if he has anything open. I'll also ask my brother he rents in Goodwell. Your friend can check in Goodwell maybe someone flunked out and a trailer might be open. Just tell him to go to the two gas stations and ask, at the one on 54 there is always 2-3 people sitting around doing nothing during the day.
