I would hazard a guess that there would be fewer tiny houses sold if HGTV stopped doing a show about them ( and paying for all or part of them for the participants ).
We ran into the HGTV Syndrome when selling our house last summer/fall. Everyone wanted stainless/granite in the kitchen and "updated" bathrooms. I did a stainless facade (stainless panels on the dishwasher and oven, new stainless microwave, new stainless fridge) and the next prospect bought it.
