There are several great resources for data. 

The differences lie in how they aggregate, update, and present the data.

The data @Devin Conley posted is pretty solid from my experience (I do not know Devin nor how he sourced the data, just going by my own investing experience).  

At the moment, our data is only available for Philadelphia.

I’m exploring ways to automate my deal analysis process and was wondering:1.Is there a way to programmatically pull MLS data?

Every market will have a data center, not sure how this will deviate from the curve of market-based anticipation.

That puts any of their data sets into serious question.

I'm data driven and would love to immerse myself in IL, AL, MC specific property, demographic and investor-centric data sources the same way I've done in my previous area of focus.

I'm looking at investing in several out-of-state markets (potential BRRRR strategy in mind), I have a list of qualifiers that I'm sussing out to determine viable markets but would love to know: what data helps in determining a good market to invest?

As with every loan process, there are terms and steps the foreigner needs to follow, such as the loan application, which includes pre-qualification and property evaluation.
