I secured one a week ago as another investor was arriving to look after I did.  

I have, by no means, "arrived" nor have I "made it" so please hear me out from a beginner's point of view.

Best wishes    I just ordered this course and am anxiously waiting for its arrival.  

Be sure to spin the idea they will have additional income from selling this to you on contract and if you default, they can sell it again [careful with this, keep their motivation in mind].From your perspective, before you arrive do your homework:  How much is fair market and how much can you pay?   

So, it will be worth to YOU whatever your cap rate / NOI / ROI / CoC (and whatever other investment criteria) fits in with YOUR goals (then subtract another educated-amount for contingencies to arrive at your own MAO).

They finally arrived in a white van.When they arrived they were full of ideas about painting one of the bedrooms, replacing the range with their own range which they had in storage.

The reason we're doing it tomorrow is that Brandon arrives in town tomorrow and we wanted to do something while he is here.

You basically construct an income statement identifying potential gross income, the effective gross income, expenses to arrive at a net operating income.

For example, how did the owners arrive at their asking amount?

Luckily, I didn't have work and was able to arrive within the hour and unlock his unit for him.
