Purchase price: $15,000 Cash invested: $25,000 Sub to deal - paid the seller and wholesaler $15,000 + $7500 closing costs to assume $84,000 mortgage with a monthly PITI of $575.

I do business with people I have met before, not the sudden opportunist who wants a deal.  

The truth is that if you find the right deal, you can make pretty much any market work but if you are looking for consistent deal success that narrows your options down.Some investors look for simple signs like the "Chick-Fil-A" test.

It sounds like you could have a promising deal, so lean on your experienced agent for guidance and go take action!

This does not align with buying most buildings in cash.Once you progress in your investing efforts you may come across more UHNW individuals, family offices and institutions who would take the lower return for limiting risk (all cash deal).

If you're strictly seeking off-market deals, I recommend connecting with and working with a reliable/resourceful wholesaler instead of a real estate agent.

How do I determine rental prices in a neighborhood and the demand for rentals in that area?

One thing that may work is doing a Subject to Existing Financing deal where you will buy the property from someone but not payoff their loan.
