After acquisition, how fast do workers begin

[Francis Rusnak]

In a perfect world, the General Contractor will have his guys in the property right after you get the keys on each new flip. 

But how long does it normally take to get workers in the house; assuming you couldn't get into the property prior to purchase to get bids. 

I was thinking to get your own demo crew and have them begin right away. While they are going you can have GCs in there to get bids. But that doesn't seem like it would work because demo would take 2 days max, and there's usually a gap from when GCs can start.

Any tips to get the project off the ground as quick as possible?
