Wow, the Montana couple did not seem suited to each other at all. All of that drama about having to find their "forever" house could have been avoided if they had just rented an apartment for a few months while looking for a house to buy. If it's to be a forever house, you don't want to have to be pushed into making a rushed decision, but I guess that was the contrived drama assigned to this episode. They certainly weren't homeless, as the wife so dramatically put it.
I understand that people make important decisions in different ways, and I think the husband was more introverted, and deliberative in his decision making than the wife who looked for different things. I don't think that should have been a negative when they toured the houses and went separate ways at first. I can understand the husband wanting a separate space for himself, especially with the type of job he has. Most people benefit from a place to have some time/space for themselves. The wife probably has one too, but either won't admit it, or it's not as important to her. She admitted they made decisions differently, and she admitted that she acts more quickly. She also said she was trying to be more inclusive of his opinion in buying the house, but I think she needed to work on that last one a bit more.
One of the houses they toured had a very odd narrow storage room, with customized shelving in the basement. Looked like a place where you could store tons of food. I was thinking maybe the former owners had built it in preparation for some catastrophe. I love it when a house has some quirk like that.
