For over a decade, I’ve focused on multifamily acquisitions and asset management with firms ranging from small boutique offices to large syndicators.

I don't know whatever happened to the court case, but I do remember it was in the 60-80million range of renovations apparently needed to the structure. 

This will never lead you to factual numbers because nowhere in  your analysis formula, do you have any specific facts...that are not ranges of numbers.REI analysis isn't based on ranges as a starting point to accumulate numbers that are specific. 

Since rent range is pulling from property managers the data is cleaner, because so many self managed property investors market their property way too expensive and they will never get that rent, it is just hopes and dreams.

Or, you could ask for a rate quote based on a range of credit scores and you can figure out what they'd charge you on your own.

For instance, in Kansas City, you can find solid rental properties at a fraction of the cost you’d encounter in California, typically ranging from $150K to $250K in desirable neighborhoods.

As @Daniel Hyman said, getting into the 3+ property range can overwhelm people and take too much time.

House hacking a duplex would be my ideal situation, but I find it challenging to find anything available in the DFW area in my price range.

Quote from @Kornelius Friske: We have a STR located in peoria AZ. it's 6 beds (garage conversion) and about 3900 sq ft in total. our energy bill last month was $450 and has been hovering in the $350-$450 range since we went live in august.

I looked at the market and see there's a large selection of 4bed/2bath homes in your price range.
