In my eyes this hurts someones image not enhances it.

Not only will it enhance the marketability of the house, it's a way "greener" option in terms of saving energy and water!

Like I learned to sheetrock and mud (and decent flat texture) in my garage (who cares if not perfect).

Drywall and texture completed. 

There is a lot of wiggle room in "five figures" statement but I would venture a guess in the low "five figures" Ok, maybe more if you had to have a super model digitally enhanced frame by frame.

There are a bunch of holes in walls and ceilings now that will have to be fixed and then textured.

Hi, I am trying to turn on the enhanced signature in my profile but the checkbox is disabled.

As a disclosure, I sat for the exam to enhance my investment opportunities and knowledge, and to reach out to more investors along the way (I am hoping therefore no licensed real estate here really wants to put others under the bus - That will be just plain wrong though and against the spirit of agents vs. investors collaboration BP is trying to establish!)

If the hollow door has that fake wood texture, use a toothpick on the Bondo to recreate it. 

The concrete will likely do a great job but in my instance $1,800 is pretty cheap insurance to prevent additional sheetrock, texture, painting costs.
