What would you do with $30,000

[Heshel Mangel]

I am sure this question has been asked before, I am doing some research and survey, and would appreciate any suggestions, thoughts, and advice. 

The scenario: 

"I have been a casual real estate investor for some time, but am looking to ramp up and create a full scale business. I have $30,000 saved away for whenever I should want to start a new business. What is the best way to allocate that money - is it (1) networking events (2) marketing programs (3) business development - software and hardware necessary to build out the business (4) buy a property"

For the sake of keywords - let's say this real estate investor was in Cincinnati, Ohio - or anywhere in the Midwest, and was looking to buy and hold multi-family properties. 

Thanks in advance!
