And one simple question...Are you going to buy more investment properties, or invest in any way, in the future?

Ours are very simple boxes and we get economies of scale since we build multiple houses at once. hope that helps  

I mean, is it as simple as finding a few recent sales within a few miles on zillow or is it as complicated as finding a commercial RE agent who I'd have to pay to give me a CMA?

It seems like a simple thing, but reaching out in BiggerPockets about getting started as a real estate investor is a great first step.

However, i would like a person with multiple rentals to help guide me to avoid some simple mistakes.

Its simple in practice, however you need to make sure the numbers work.

and some guidance from the FTC is here: https://www.ftc.gov/tips-advic...Simple solution - DON'T.

Based on your budget, it's pretty simple.

We recently relocated to Phoenix last summer and I'm starting to look for recommendations for local credit unions here in Phoenix which are trustworthy, low rates, personal touch, easy/simple to work with, etc. 

That is interpreted to be the simple reading of the question.
