@Jim K.
Wow Jim, that felt pretty rude, and you sure made a lot of assumptions about me when you know nothing about me. Normally I wouldn't respond, but since you publicly shamed me in front of all my friends .....
First of all, I never called myself a master builder, nor would I be so ignorant to do so. I would also never claim to truly know what trades people go through after performing physical labor for decades. Wow, what a tough and honorable career.
However, I have been the "grunt guy" on about 10 different house flips through high school. I do have two degrees in Construction Engineering. I have worked for a general contractor during my college years. Again, I was the grunt who got loaned out to any sub like a slave to do the work non of them wanted to do when my superintendent "owed them a favor". I have worked with multiple unions, pile bucks, carpenters, pipe fitters, plumbers, you name it. I've been involved on projects installing dams, street cars, BNSF train bridges, mechanical systems at Intel, dental labs, 30 story buildings, you name it. I'm sure I could impress even you with my insider lingo. EVERY time I started out with severe judgement like you just displayed, from the trades people and EVERY time gained respect of the trades in a matter of weeks. How do I do this without putting in 40 years of manual labor and destroying every joint in my body you may wonder?
While I won't respond to your 101 specific questions, here's a good example for you. Just a year ago I had a tenant die and liquefy all over the floor. A restoration company took out all the remaining guts, carpet, etc until it was safe to work with some basic PPE. They left the body soaked plywood. I also "inherited" all the tenants junk (which all stunk like you wouldn't believe). After 10 guys quit the job site and were puking all over my yard, guess who the one person is who cut the plywood out, heaved it into the 30 yard dumpster ALONE, and yarded out 4.7 TONS of junk, almost all ALONE.
Each and every one of my guys knows I wouldn't never ask them to do anything I wouldn't personally come out and do myself. They know the reason I have what I have is because I'm willing to do what 99% of the population isn't willing to do, even if they knew with certainty it would lead them to become a millionaire. I could list of 20 examples but won't. I've had the back spasms, had the fiberglass insulation in every crack of my body, coughed up the black crap in my lungs, had the welding burns, etc, etc etc. It's not about me though. And again, with all sincerity, I'm not a master builder, and I'm certainly not up to par with the level of skill most of the people I hire possess.
There is a huge gap between the difficulties of blue collar and white collar workers. Even though I've had many of their experiences, of course I couldn't extrapolate that over decades. Nor could they understand what it's like to have a dead beat tenant stick their finger in their nose and tell you they are going to sue you for everything you've ever worked for and be the future landlord of your building.
This post is getting long, and I could write 10x the amount here. I still stand behind my advice to the poster though. Somehow us ignorant, soft-handed, privileged, white collar folk need to overcome the common immediate judgement that you've displayed on your response.
