I worked the Marfa, Texas area for some years after the financial crisis up to about two years ago and a great or grandparents house bought for a few thousand back during the Cuban Missile Crisis or just prior are/were upwards to a quarter of a million recently, and basic, sold "as is". Mijo and Mija (the heirs) were "Cha-Ching'ing!" and wanted nothing to do with the intra-city infighting among the natives and new and young hipsters.
Yes it started when artists moved in during late 80's, early 90's. Now, legal eagles from So Cal and parts of Texas want(ed) a "second" and really drove up the price. Marfa is in some of the best hunting spots in the U.S..
