This is just for my walkthrough to see how I feel about the property and targeting serious issues without the affirmation of a home inspection report; cracked foundation, holes in the house, broken windows, wet walls/floors/ceilings, wet crawlspace, etc.

The tiles adjacent to the wall and the baseboard have been removed, the drain tile put in, concreted over, and this has left a depressed section 18”wide that has a drop off of ¼” from the existing tile.For a quick, low-cost solution, I was thinking of putting floor leveler in, then painting it a similar color to the tile that’s there, then putting the baseboard.

All walls will be down to the studs.

The waste line will be more of a challenge, but certainly doable. 

If the money is spent on "repairs" making the house more usable, it'll probably be a higher return than painting the walls a different color and installing new lights.Many remodeling projects will have no net gains in property value so be careful how you spend the money.

Finally at the end of 2020 my wife told me; "you are just wasting money on this".

However, no one said you drive buyers around… I basically said your working a 9-5, wasting your life to break it down slowly for you. 

Removed a wall to make a open concept kitchen with a new layout.

I suppose someone could measure the interior walls instead of exterior, but it shouldn't make that much difference...
