Buy & Hold Investing

[Cynthia Hughes]

The past few weeks my wonderful agent has acquired several "buy & hold" properties with long term tenants in place. Many of which I have past on to other investors. 

As a beginner investor, what are the pros and cons of becoming a buy and hold investor? Value has already been added to most and the others are having value added so I will not have to do anything. Asking price seems to be below market and great ROI. I just want want some insight.

Thank you all in advance.
