I put your comps and those that are for sale around them in realtor.com or zillow's pictures to get a better handle on qualitative differences such as floor type, countertop type, appliance quality, etc...Once you identify what's different you can then see what a particular difference translates into in the form of a raw dollar amount.

The fact that there is a section 8 tenant in there, or was there, does not translate to easily rent able house.

Translation (elaborated some):I can fully understand why the homeowners policies wouldn't cover it, but I would assume that the builders liability policies should cover the faulty products.

Further higher down payments mean less borrowed money which translates into less monthly payment burden on the borrower. 

Translation from sfr sure is a big change.

I started a member blog with the translation into Spanish here at Bigger Pockets. 

Most investors seem to want to be in edmond which translates into too many rentals as you said.  

@Sam Hadad Sorry, the point I was trying to make was lost in translation. 

https://www.amazon.com/LIQUIDATION-ENTIRE-Millionaire-System-Bresser/dp/B00IVTTBSO - List More Sell More is mentioned on the most recent BP podcast by someone who became successful as a real estate agent and in other aspects of the field, I'm guessing a lot of that would translate to marketing skills as well.

Not sure if this would translate as well to SFHs.
