Least expensive solution to an ugly all stone interior wall.

[Lucy Auburn]

I would like to try to get into flipping and trying to do as much due diligence as possible, calculating the estimated costs to see whether it would be worthwhile. This house has good bones, just needs to be updated with tons of paint and updated kitchen and bathrooms. Ideally, I would do something with the stone, probably color washing it. But there is way too much of it. I am thinking of going with a French farmhouse look if I take on this remodel flip.

For those with more experience, my question is what would be most cost-effective as far as dealing with it. 

1. The wall to wall base has to go. How much would it cost to get rid of it?  

2. How much to demolish three-quarters of the wall first or would you leave it and cover it with something?

3. How much would it cost to cover up three-quarters of the wall with sheetrock?

4. Is putting stucco over the stone an option and how much would that cost if I trowelled it myself?

5. Any other cost-effective suggestions?
