I’ve spoken to many agents and they don’t seem to know any strategy or how to utilize the benefit in this manner.

The argument I currently have with multifamily lies in the exit strategy.

Don't do it; put the max in "strategy b".

Every strategy has it's advantages and you don't have to choose just 1 strategy. 

My strategy is to cherry peak the really good deals and wholesale the rest.

@Jay Gousman it all starts with educating yourself on the potential investment options and from there you can begin to build the framework of your investment strategy.

I have several exit strategies which allow me to pay more than one flipping it.

It has tenants, I have had one month of vacancy since 2012, I would prefer to sell it without an agent, however I worry that there will be dozens of investors wanting to walk through the place, disturbing my tenants, making them antsy and the investors then low ball or otherwise do not generate reasonable offers.What is the best strategy for making sure the potential buyers are serious before letting them in?

Networking commercial brokers is a strategy I'm going to pursue.
