They have addressed the issue of depreciation of components, but not the actual methodology of the study.

But as someone who’s been in the trenches of real estate investing for almost 30 years, I continue to see some flaws.Some of the flaws I have witnessed are when tech-driven companies seem to lack backing from experienced underwriters or seasoned real estate professionals.

I am trying to automate my data collection through excel.

Below is some copy & paste info about our methodology:----------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

@Abrahm Dimmitt,PropStream has a lot more data in it. 

Purchase price: $20,000 Cash invested: $45,000 Sale price: $99,000 Contributors: Peter Vekselman Partner Driven and Amanda Frecks teamed up for an exciting flip on Main St, Grainfield, KS.

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

@Dana Yobst While it may seem like a simple concept, it's actually a very complex process that requires significant documentation as well as specific methodologies.

There are several great resources for data. 

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.
