Hahaha. Well, house hunting with me would drive people crazy, it seems.
I've moved more than I would like and might be able to explain some things:
"Top of the price range" -- I have never been honest with a realtor about my price range. It's all a game and I know the rules. Plus, I always have three numbers -- the number I'd like to spend, the number I plan to spend, and the number I actually spend.

None of these numbers have anything to do with what the bank says I can spend. With relatively artificial top price ranges, it is easy to buy at or above that range. Basically, my house hunting range reflects what I will spend on "a" house. If I find "the" house, I'll go to the top or a bit over.
"This will work" -- common phrase for me. I tend to buy for location, which means I'm often looking at the least expensive homes in a more expensive area. I am looking for a home that will "work." There are certain things I know I can live with and ones I know I can't. "This could work" comes out when I hate the cosmetics of a home but can see the potential in the bones. Or when I'm in a location I really like, but am less than thrilled with the house -- can I work with it, even though I don't like it, or will it really be a daily problem.
"Space" -- I do probably say this. I do think is terms of space. Rooms are just were the walls are right now. I usually look at a house and think about how the space is arranged. I'll repurpose space or think about how I can rework the flow of the house if necessary.
Granite -- I couldn't care less about. It is much cheaper to put in than people tend to think. (When I sold one house, I put in granite because it looked like I spent 3 times as much as I actually spent -- house sold the next showing after it was installed.)
Wall color -- I also don't care. Wallpaper, on the other hand, will give me pause. I won't not buy a house because of it, but I will have a visceral reaction against it before my rational self returns
Entertaining space -- actually fairly high on my list. We like to have people over. I like to have space to set up tables and that is conducive to people being comfortable. I will trade bedroom space for "entertaining" space any day. I also find that homes with good entertaining space are good for family living -- it keeps us out in the open, while still not being on top of each other (and not retreating to bedrooms).
Home office -- actually important. We do a lot of work from home, so having a dedicated space makes that possible. It needs to be quiet. It is also nice to be able to shut the door on work so it isn't staring you in the face from a corner of the living (or worse, sleeping) space.
I also walk through houses picking apart everything. It doesn't mean that I will end up making a decision on that basis, but if I don't care enough to comment on anything, then I'm not really that interested in buying it.
Even though the show is fake, I still love being able to see the houses. I tend to watch just the recap at the end though
