Very good point.In the case of Arizona, I have been unable to locate any state law / code that suggests Arizona may have additional regulations. 

My point is I'm not interested in having a second job.Currently doing analysis on identifying top zip codes for the facility based on criteria like age distribution, median income, education levels, % of home ownership.

It’s tax free profits due to our tax code.

These are professionals with additional training and a stricter code of ethics.

EVERYONE is trying to crack the motivated seller code with technology or other voodoo tactics but they fail to realize that the inherent simple characteristic of "motivation" is exactly that it can't be equated, formulated or coded.Motivation is not about "if you exhibit characteristics "X", "Y", and "Z", you have a higher chance of being a motivated seller". 

Those effected go well beyond the property owners, the economic contribution of RE and subsequent economic loss in the form of: management, maintenance, landscaping, caretaking, hospitality, tourism, contracting, designing, pools and gardening is economically catastrophic and will reverberate well beyond specific zip codes.

A shower is generally acceptable as long as it meets building code requirements for plumbing and drainage.

We had to remove the windows we had already installed in a 1925 house and reframe the openings to bring them to 2023 building code.  

I think there is a way to do it by zip code but that's not really granular enough.

Newer construction code requires better earthquake-proofing, but it's still aimed at preventing a building collapse rather than holding the value of the structure.About 15 years ago there was all the talk about "100 year homes" but I haven't seen much come of that.
