Buying from a wholesaler as opposed to buying from the source

[Tony Leighty]

As a new investor, I'm trying to gather as much info as possible before I jump into the wild.  Reading these posts have been great but as I get further into the notion of wholesaling the natural question has popped into my head.  Why would an investor want to buy from a wholesaler at a marked up price, why wouldn't they just buy from the source?  What benefits does buying from a wholesaler provide?  Save in time/sanity?  

Sorry if this sounds like a remedial question but I'm curious as to the answer.

Thanks in advance!

Cash buyers (rehabbers) want to spend their time rehabbing not looking for deals. If a wholesaler finds a good deal they will make $.
