The vets here are well aware of this and its often mentioned in the volumes of educational materials everywhere. It was no sprise to me, even though this is my first flip project, because i have hired out for dozens of projects on my own residences. For those just starting out or planning on rehabbing, hopefully its helpful.
I thought I would share some real, current examples of the variances in job bids from contractors. The following bids are for work in central VA. The actual work request and bids were for the same house, the same exact job/material request for the most part:
Replace Roof (5 bids). 3600, 3800, 4600, 4700, 6110
Upgrade Electrical Panel to 200A (5 bids): 950, 1185, 1250, 1400, 1400
Vinyl Siding (3 bids): 6500, 11000, 12650
Replacement Windows (2 bids): 5600, 7500
The range for the combined work for these 4 jobs alone is over $11,000.
This says nothing about the quality of the job that will be provided by each contractor, but as stated it is all for the same house, the same work request, and the same or comparable material/grades. All contractors are licensed, insured, have have no negative feedback trend that I could find (my own criteria).
The lesson for those new to rehabbing: spend the extra time to get multiple bids for the work you are farming out!
