Late to the party on this thread, but one thing that gets me about these house renovation shows is that they make the homebuying process seem so easy. Here's three houses, we can probably get them for these prices, take your pick. I know they are all contrived, but probably more than 75% of the time something will fall through, loans won't get approved, offers won't be accepted, etc.
I do like Fixer Upper because I love Joanna's style, but I agree with a PP that the decor is FAR beyond the reno budget. Just last night, their reno budget was about $30,000 which is not a lot as far as house renovations go, and they were knocking out walls, moving doorways, etc. Obviously had to cost quite a bit more. As with all the reno shows, they also don't do every single room in the house so if must look funny for the homeowner if some rooms aren't done up in the same manner. And lastly, very few actually put a TV in the living room. The designs are usually really nice, but impractical for how people are really living. They're set up like museums.
Perhaps a spoiler but may be interesting for some... I've heard/read that on Love It or List It, people who want their homes redone will contract to be on this show and will essentially receive the renos for free. They then film two endings - one saying "love it" and one saying "list it" and the producers will pick which ending they edit in. So, all the people on the show are really staying in their homes and just looking for free renos.
On House Hunters, they filmed a few episodes in Rochester, NY which is near me. The people told the local news that House Hunters joins them AFTER they close on their house purchase and films the house they bought. Then they film the people viewing two other random houses that the producers choose - some of which may not even be for sale. This is done because of what I mentioned above - sometimes loans and deals fall through, so with the people having already closed, they have a secure ending.
