The reason I like doing this instead of using a service like Mint is that instead of uploading my purchases at the end of the month and viewing how I did, this gives me a real time view in the middle of the month and I am personally entering the data, so I know the details more intimately. 

My gut is telling me this can be gold but I really want the data to support.Hope I was clear on what I am asking for.ThanksJermaine

Then look at the cost of some of the major repairs that may need to be performed. 55% is a good Estimate but you'll want to look at all the real data before making a hard comparison.

If so I would ask for the actual data.

Hello,I am thinking to invest in Los Angeles, want to know where I can find the data of Los Angeles SFH Rental Price Index/Chart?

In less you are very in tune with the local market and data it is hard to see how healthy our market is. 

I was wondering what some investors might say about the standard output data vs. standard mortgage leads.

These skills have helped me do some research on properties but I am, again, not confident I'm looking at the right data or excluding some necessary gathering all the information I need.

I believe @David Faulkner only used San Jose as a data point as it's much closer to you than he is.

From there you have buy and hold investors for rentals and they tend to pay the most for SFR investors.Look at the data for MLS and see that over the last 6 months for instance 200 properties sold to investors at an average of 140,000 sales price.
