Pipes can eventually start to weep (similar to aged cast iron).Buying a property with galvanized plumbing, or old cast iron drains, is not a deal breaker, but you need to budget their {maybe not immediate, but near to mid-term} replacement into your cost modelling of the property.

I've painted copper black before bringing to a job site in bad neighborhoods, so anyone watching would think it's black iron pipe

I'm open for hosting a totally informal BBQ at the house, BYOB and BYO chair too.

Yea, I'm sure some people may disagree with my approach but if you try and rule with an iron fist, it just won't work in most cases.  

Galvanized and cast iron plumbing will be an issue.

Aside from REI, I’m an avid hiker, enjoy traveling (lived in Australia for two years), and am a sucker for good BBQ.

Yes, I would have more money in my bank account if I didn't put in a pool and built-in BBQ/entertainment area in my backyard but my goal isn't to have the biggest bank account.

Ironically the sports metaphor fits.

The idea of a backyard BBQ with friends and family is just too much engrained in the American dream.

Ironically, this is also why we have the fee schedule we do for servicers.
