How to Evaluate a rental portfolio?

[Jesse Krall]

So i have been talking with this older gentleman that has 6 places he eventually wants to sell. He is the blue collar type and has kept these places in great shape. Some of them in to good of shape but he is wanting to retire from it soon and i have been slowly selling him on the idea of doing it all at once with me helping him find a buyer. However there are challenges that are new to me. 

1. He wants way to much i think

2. I never did a portfolio buy is it a different Cash on Cash Return?

I would say solely based off the rents its worth around 500K i think he wants around 1 million    

Total rents are $72,500/m but Easily could be raised.
