Too many good options to go over here but after a quick reading of your data how about -  1 complete the ADU and move in / 2 rent out the house / 3 cash-out refi / 4 purchase next property  - you get good cash flow on this prop and plenty of capital for your next one.

However, I'm hoping to get some advice about what cities are good to explore for properties in the 60K-100K price range.Thanks.

Currently with sites like zillow the data is low (not many rental Bc of high demand) in the area that i am looking at, so it seems tough to get an accurate rental comp?

of course each case is different, but is there a data sheet or something that shows what differences between comps is worth. 

there is no possible way to answer this question with the data provided

You are local to LA, so we have vendor expo's and one day event over the weekend's, go there and spend few hours and connect/learn/explore, most of them are free but they will try to sell something :)

I align with you, that I want some basic operational data when assessing offerings, particularly an offering like his, where the deals are identified and known.

Just exploring to see if there's something there... 

So honestly unless you want to move, I would explore the Denver market and see if you can't make it here.

It’s against PropStream’s terms of service to re-sell their data.
