I'll explain my methods to arrive at the numbers below.

Then I drive by the store, get the part, and arrive with the knowledge to do the repair...Books...Although dating myself, I still like a couple of good do-it-yourself books (anyone under 25, google "book" to find out about these paper relics of the past.. just kidding)....

I'm not sure about upfront costs, everything was in place before I arrived.  

Or, how will you know if you have "arrived?"  

Look at inventory consumed and consumption in cycles, then you can deduct for waste and arrive at cycles run/income.

Due diligence verbiage is standard in a contract in GA, however, none of these buyers are using a buyer's agent and, as a result, their offers are not arriving in the form of contracts.

Yes, you arrived at the correct understanding.

I balked and then they replied "the EARLIEST you may arrive is 1pm."

And then the reports arrived from the official sources, the truth that London was safe, Napoleon was defeated.
