(These averages represent state-level data, and individual cities may levy additional taxes.)To achieve the same level of cash flow as a property in Nevada, you would need to generate a higher cash flow in Texas to offset the higher operating costs.

BUying lists is notorious for having dirty-data. 

How will I find renters' data to see if others in my area are actually making money or filling spots on their section 8 properties?

You already know those answers lol.You may find this interesting; My broker scraped the CSLB master list & found only 210k(+-) "active" licenses left.

If we had more data, lets say 20-100 people and all say the price is the problem, then yes, I would agree 100%. 

I'm a sucker for data so I'm always looking for new sources.

Record lease data using software or spreadsheets, correcting any errors or discrepancies.   

You might also want to look at recent sales data to see how fast homes are selling and which neighborhoods are on the rise.

If your credit is good and you can scrape $25K together, you would be better off buying a SF rental.
