I wonder if the people reviewing this show know how to believe their own eyes? A new roof is a new roof. A tile bathroom and kitchen backsplash is a tile bathroom and kitchen backsplash. Stainless steel appliances are stainless steel appliances.
The host says many times the reason they are doing this in 24 hours is to limit holding costs and make more money. Are these high-end renovations? Is this is show focused on design? No and no. It's a show about the reason professionals flip homes... How to make money.
It doesn't mean you have to do a flip in 24 hours. It just means think about taking months or years to do it and consider how to do it in such a way as to maximize your profit. What is being shown here is real and amazing!
