However, the best way to get a feel for rental rates compared to values is to review/underwrite properties in the area - only after reviewing/underwriting many will you begin to see a pattern.

If I did, I'd find a place I really like to visit and be prepared to spend a lot of time there making connections.  

I'm planning to review where I stand, considering my current low income, to explore the best path forward.

I would spend time building your list of WHO (agent, mentor, contractor/handyman), then WHAT (house type, tenant base, work needed), then WHERE (location).

How much will you spend in repairs on a 1920's house with renters ? 

Make sure any lease agreement you use complies with Arizona's landlord-tenant laws, including required disclosures (like bed bug information, for example).If you're unsure, consulting with a local real estate attorney to review the agreement can provide peace of mind and ensure you're fully protected.

You can easily look them up on https://nmlsconsumeraccess.org/If they are a commercial lender, you may want to check for google reviews

However, if you’re not ready to jump in yet, you could spend the next couple of years building your savings and learning more about real estate to feel more confident when the time comes.

Based on the questions you are asking I think you need to spend more time listening to podcasts like Bigger Pockets and Bigger Pockets Rookie.

So you're willing to pay $30,000 for their furniture when you could spend $5,000 on your own?
