re: People who went from nice older home to newer one

It's not the materials. It's the attention to detail (lack thereof) that makes the difference. There are so many problems that can crop up that need to be dealt with in a typical build that simply - aren't. These problems can compound and result in a shitty house. It isn't necessarily going to "fail" an inspection, but over time it will be a headache.

You can have two different crews build the same house with the same materials and get wildly different results.
