Buying from a wholesaler...logistics?

[Shiv Jey]

When you guys purchase from a wholesaler...how does that work?  Who draws up the contract?  Do you use your own realtor or lawyer?  I'm not sure if I trust the wholesaler to draw up the contractor and help me with inspection and appraisal as an out of state investor.  How do you guys do it?

Ex:  Wholesaler X from Utah has a house to sell me that he's rehabbed and ready to go.  He wants 48k.  I do the numbers, it all checks out.  Great!  Now I want to make sure it was rehabbed well and there aren't lurking dangers, so I want a good inspector to look over it.  And an appraiser to appraise in order to finance it of course.  I do my own comps and ensure that it's well-priced.  All checks out.  I tell him I'm interested, let's do it........Now what?
