Question about buying from a wholesaler

[James Bitakis]

As a newbie looking for my first investment property, I am a bit confused on the logistics of buying from a wholesaler.  A lot of them want fast closes and 2K Non-refundable earnest money at the time of contract.  

Questions:  Can I inspect it and have a formal inspection before paying the 2K?

Shouldn't I use a Real Estate attorney?

Do I find my own Title Company?

How do I know I am getting a clean title?
