Inspector vs General Contractor

[Ben M.]

I am working with a major wholesaler who does not allow inspection contingencies with their contracts. It seems my option is to bring either an inspector or general contractor to verify rehab costs. A couple of questions came to mind:

1) Paying for both a home inspector and general contractor might be too expensive. Which one would be best for this job? Would a general contractor be able to evaluate all things that an inspector can including termite/pest damage etc?

2) How does one approach this situation since it seems I may have to pay them to check out this property before I even have it under contract.. What if someone else locks down on the property while I have it checked out..?
