Regardless, I'm going to be buying a home for a daughter so I was just curious to see if getting one with galvanized pipe & re-piping was worthwhile. In light of the cost, I can now see that this isn't a good option. In todays real estate market it's too easy to buy a home with copper or plastic pipe at an attractive price - so that's the way I'm going to go.
By the way, I'm in Warren. Many years ago we lived in Royal Oak - in fact we just drove through there this afternoon.
Copper(type L), Pex A, Pex B or wirsbo are the only pipes I'd use in my own home.
Make sure if you are buying a house with new piping, its passed plumbing inspection and you have a home inspection done to address any issues(PRV not working, expansion tank etc). Good luck!
If you do buy a single story place with a crawlspace, it would be the easiest labour wise to repipe the place. Easier to access and you dont have to rip out drywall and replace it after.
