Update - I have decided to dip my toe in to test the Contractor Waters with a small job in my residential home first (a 6x7 hall bathroom).
I requested six bids but only received three. I am utterly amazed by not only how different the pricing is but the various ways the contractors provided their estimates. The differences range from a two-page, fully itemized bid to a text message with just the total cost amount (LOL). Luckily, thanks to reading the Bigger Pockets forum threads, I was able to ask the right questions in order to do an apple-to-apple comparison.
Now that I have the numbers (see screenshot below), I'm looking for some tips on identify GLARING inconsistencies, hidden or missing costs and any general advice on what to watch out for before making a final decision on contractor choice.
THE JOB: relocate toilet, tub/shower and vanity which requires moving plumbing, electric and a heating vent. move tub/shower under existing window (NOTE: one contractor suggested replacing the window with a glass block window).
