Most of our SFHs on southside we do make the water spigots not functional so they cannot fill up pools or give a car wash down the alley(both of these have happened many times over the years)

Buyers tend to purchase (pay a certain amount) as a function of the whole, not by itemizing components, assigning a value to each, and adding up the multiple results to arrive at an offering price.

You can use the search function for answers people give but none of those answers other people give will be relevant to you. 

Wonder auction.com have search function of past foreclosed home so I can check out initial bidding price and winning bid and such.

Sherri, it sounds like the house is not habitable as it doesn't have functional plumbing. 

In my area, there are still many plastered homes, hovering on the edge of functional obsolescence but with decades of life and profit still left in them in the right hands.An experienced investor in such properties in my area knows the ways many cases of localized plaster failure can be fixed, what can be done to repair and replace failed areas, how to use plaster and drywall/sheetrock together to achieve acceptable final results. 

I'm in the process of buying my first flip, and the house will need an addition on the 2nd story to make it for functional for my target buyers.

Then I'm functionally seeing the home AND seeing it through the experience of a local real estate resource.   

I could have focused the rehab on market trends and functionality of the home instead of my likings.

Additional items like handrail functionality, smoke detector and door locks will be checked.
