What is the best hands-on experience for a buy and hold investor?

[Daniel Galvan]

Hello,

I'm looking forward to begin my buy and hold investment career next year; I have some financial goals that I want to complete before investing. However, in the mean while I have strong desire to get hands on experience to learn the business via either assisting an investor or part-timing with a company in the field. If my goal is to be a buy and hold investor buying 1 property per year, who should I be looking to work with: 

1) A wholesaler to learn how to find deals, 

2) A real estate agent to learn the process and network,

3) A contractor to learn skills and to do better estimates, 

4) A property manager to learn land-lording skills?
