​is a wholesaler considered to be a real estate investor?

[Kenneth Wiley]

the only money that might actually be needed for a wholesaler to my knowledge/belief is a Earnest Money Deposit?

how to do a title search for each state to see whose name was written down in the legal documents right?

or maybe if we can find the name of the title company/attorney involved we might be able to find whose names were written down on the legal documents.

@Kenneth Wiley generally defined, an investor is deploying capital for return over time. Someone who owns rental properties or stocks would be considered an investor. 

Wholesaling and flipping is a job. You must continuously spend time and/or money to get income. This is an active profession.

Not that it really matters. Call yourself an investor if it makes you feel better. Very often people who start in wholesaling and flipping move into rental properties due to the passive aspect. Worry less about labels and more about the best way for you to acquire wealth.
