You’ll see that you are tripping over dollars to pick up pennies. 

As usual, just my 2 pennies. 

Worth every penny!

I've seen this with electrical (kobb and tube, aluminium, some newer copper wiring, no grounding, or faulty breakers) as well so its something to note with older housing stock.Best of luck on the property search and feel free to reach out for more of what other investors are dealing with or financing scenarios.

In that case save every single penny you "make"!

Their REStore retail locations are amazing places to score all kinds of lightly used furniture for pennies on the dollar, all while benefiting a great organization.

Still, I would imagine it would cost a pretty penny and may not be worth it.

It's common in commercial and industrial spaces, in fact, to use the copper supply plumbing as part of your ground grid. 

I would be taking a hard look at all plumbing in the entire house before I spent a penny on drywall repair.

Sometimes it's tempting to sharpen your pen too much and save pennies but lose dollars in how your transaction unfolds and how quickly it happens.
