It should include details like the purchase price, property description, and terms of sale.

I've been toying with the idea of adding an ISA to my sales business.

If you are looking to do real estate sales as well you may want to find a brokerage that hires for both at the same time, and check their credibility.

I do generally agree with the sentiment of Austin and the other hosts that fundamentals will always win out in the long run, and this by nature is a long term industry, even the sales side I'm learning.  

Your new ARV(after repair value) should be supported by an adequate amount of comparable sales in the area(duplex's).

Jan we had 12 buys 10 sales. 

But on this specific guy, I jumped on a call to explore the program and it was a high pressure sales call, it did not feel organic, not trustworthy and certainly did not feel the right fit.Why would someone spend 10k on a so niched-down space of real estate when they can get someone for the same amount to teach him/her everything?
