The risk here, I imagine, is that if you do have a vacancy it could be a big ouch once a HELOC is used to extract cash for the next investment. 

Some key numbers extracted from the screenshot below: - Purchase Price: $95k- Rental Income per unit (monthly): $670 (based on myrentrates analysis for 1BR 1BAs)- Units: 4- Repair Costs: $15k (total guess, but even with a $100k rehab/repair cost the ROI would be 12.9%). - Cash Flow per door: $340.29- Cash Flow, all units: $1361.16- CoC ROI 39.26%

We end up with an investment cost to value of 8.4% (started with just over 21% investment cost to value).It would be nice if we could get 100% of our full investment out but so far we are not there unless we have had some market appreciation (most of our RE we have all money extracted but it was helped by the market appreciation). 

Did you find it extremely dull and hard to extract a lot of concrete knowledge from it?

However, it appears his return could have been greater with more leverage (longer term loans, extracting money from property when it had significant equity to re-leverage, etc).  

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

Some town/city engineering departments may be receptive to a real estate investor, but you may need some fluff to convince others, even though this is all public record.If you are able to obtain the files, PM me and I would love to help guide you through how to extract the information that you want.

Do you guys know any tool that crawls the MLS or sites like Zillow/Trulia and extracts information from it to excel or some sort of document with everything summarized? 

Will be living here until I can extract my equity.
