While their data is not 100% accurate (my research has been about 90% in comparison against my actual data) it will shave hours, even days off of your hunt for "where to invest". 

So there is not a lot of opportunity to shave costs there.When it comes to a realtor there's certainly the opportunity negotiate commissions. 

For simple math, my interest payments are about $1300 per month so if I can shave 3 months off of the back end of my estimation on the loan I will actually be able to reduce my costs by about $500 after the sale of the property.

And in an ideal world, those that don’t rent well, will get off Airbnb in the next year or two and the cream will rise to the top.

You're going to get creamed just on the depreciation recapture that you used to offset your taxes (I assume from your W2). 

people that pay cash are really sneaky, and section 8's have nice cars.

From some brief research, looks like property management shaves about $200 off the cash flowSo $600 because $300 with expenses, cashflow etc which i guess is ok at $2500 rental income and better if it rents higher. 

Regarding the look, it is about as bland and Cream O' Wheat.

Not saying this saying this to bash BP; they don't have the ability to vet every single guest's operations and most podcast today are basically self licking ice cream cones.

Refi´s have a seasoning period.
