How big is the house?

I saw a sign posted near the highway saying something like "flipping house training" so I called the number to see what it was about.

Cosmo - I personally don't know Phoenix well, but if I had to do this in another city I would look at income levels, crime levels, and population growth (if you can) by zip code and/or area within a DMA as a starting point.

When a utility is provided by the government, if the bill is unpaid, it can usually become a lien on the house.

Told them to do a drive by and call me back with an offer :)The person who called you probably just spent $15,000 for mentoring and “education”, and is now in panic that his 250 cold calls have not produced anything .  

Quote from @Jimmy Sont: I'm looking to build around 700 sq ft 2 bed / 2 bath guest house primarily used for short to mid term rentals.

My wife and I purchased a home at the very beginning of 2022 and "house-hacked."

It will still be reported on your personal tax return.

I have not done it personally but have some insight, maybe my reply may boost your post to someone with more experience in it.
