So, with $100,000, you could afford properties totaling $400,000 to $500,000 in value.Number of Properties: You could go for one property around $400,000 or split your funds across two or three properties in the $150,000 to $200,000 range.

My advisor suggested that at my stage of the game, 8 properties, it likely made more sense to keep the extra money available or in the business to use as emergency funds or to accumulate for another down payment.

It seems you are the only person who understood the question wanting to know what a seller makes (not even sure how or why you think that).As a typical part of the DD process it is not uncommon to ask for property/entity tax returns.

Property Type: Do you prefer residential, commercial, or mixed-use properties?

I have commercial property that I currently owe $141,000 through a SBA-HEDCO loan at 4.25%.   

That may run you close enough to the price of an older single family house, so I opted for that property type. 

TP spends 100% of their time in the asset management of these properties (not property management).TP has recently invested personally in these deals and owns at least 5% of Property A.

If they've owned the property for 15yrs, probably a better chance of owner fatigue than someone only having it for 2 yrs.

The report makes a big deal about the neighborhood and local economy in addition to the property itself.

Outside of wholesaling, I'd like to explore BRRR, Fix-n-Flips, and eventually Multifamily properties.
