I put down luxury vinyl planking throughout the house and 4-inch base, except for the kitchen and the converted garage that already had tile.

Instantly and I took actions and got rid of all my Greedy liabilities that did not need, like my brand new GMC $700 a month beautiful metallic dark green 7" inch lifted truck ,fyi that was a tough one to let go 😂 but Life doesn't always talk to you it just sort of pushes you around and with each push is life saying WAKE UP!!!.....

The floor bounces due to the fact the contractor cut corners on the LVL beams & water hydrostatically fills the crawl space & the after thought sump pump installed (after the floors were in) has a lip 4 inches above grade.

They need something they can mark up and tell you, "need 32-inch door here, 40" window for ventilation, etc. 

You can’t give them an inch, they take a mile.  

A 3/4 inch copper pipe is about 1400 gallons per hour approx .

I would go through this place with a fine toothed comb and check every sq. inch.

You still run across places in my area, as you must also in Scranton, where the original floors are face nailed heartwood pine boards (of varying thickness, usually 3/4 in) over 1-inch perpendicular plank subfloors spanning the floor joists.

They have shamelessly used every inch of the property and never put any value into it.I am a flipper.

maybe not what you want to hear but with the standard today being three to five inches wide.
