Digital Homework (Analytical Ninjas Welcome)

[David Schneider]

I'm a rookie investor in the Tulsa, Oklahoma area interested in purchasing a flip in the next 6-8 months.* I have one "flip" under my belt (we worked an FHA 203k owner occupy into approximately 25k of equity). We've been saving capital and studying the surrounding markets for the best local areas to begin a wholesale/fix-flip business.
We have a zipcode measured out for where we want to begin. (Fits our business model for price range, shows strong "hot" community growth, good schools, decent inventory with few days on market)  I've been tracking home prices for a couple months now.  I just wanted to get the input of some data analytical miners out there:
1. What information is truly worth tracking?
2. What do you use to organize it?
3. What specific websites have been the MOST helpful to substitute for MLS access?
4. Any local Tulsa, Glenpool, Sapulpa, Sand Springs, Coweta investors have some tips about specific data to look for and/or areas to invest in?

I think I dropped enough key words there.  Thanks for any input and good luck with your own investing!

*Before I get accused of 'analysis paralysis,' we are actively saving capital to begin securely and this question is just to let me take actionable steps in the mean time.
