Rehab or tear down and build new?

[Jordan Bateman]

It appears there's only one related thread on this topic from 3 years ago, and wanted to get some more recent opinions from the group on this.

I have a deal in Houston that is a major rehab. In my experience, I've taken a house down to the studs pretty much, but have never taken one down to the slab or built brand new on a site.

This house is one where I'm weighing those options. The house literally needs everything from roof to foundation, mold, etc. I'm talking to contractors and builders, but wanted to get other's opinions.

At what point do you consider taking a house down completely or down to the frame versus trying to just rehab what exists?

What should I expect that wouldn't come up in a typical major rehab? Additional permits or rules/regulations, etc?

And who should I trust to handle the job?

I'm also trying to figure out what makes the most since from a timing and cost standpoint?

Thanks!
