Every single episode of those shows features a couple that has already purchased a house, and they pretend to give them two other choices to “pick” between.
Especially noticeable when they find a fake option that’s a better fit for their wants/needs than the one they actually chose and the same price or cheaper.
Yeah the one episode I watched beginning to end you could see the lady dying inside while touring her actual dream home that cost significantly less than the one they “ended up going with.” I didn’t know that was how the shows were set up so her reactions puzzled me until I learned that fact.
After that I figured that episode was the peak of the genre and never bothered again.
