AL wiring is a very real possibility. Our previous home was built 1 year earlier and less than 2 miles from this one, and our previous home had AL wiring. I'm very familiar with AL wiring. We never had any pipe problems. I think this one has had some work done on the plumbing between the house and the street as there's a big capped PVC pipe (6" or 8", if memory serves) sticking up out of the middle of the front yard

Wiring is also often not properly grounded (two prong outlets vice three). Sometimes the outlets have been replaced with three prong ones to accommodate modern electrical items but there is not ground on third prong...so you cant tell without a meter (or removing the outlet covers). Also check the fireplace damper. Many from the 60s rusted out long ago.

Look at the age of the hot water heater. Last 60s home I bought had one that was 30 years old (like the HVAC). Neither lasted long...nor were very efficient before then.

Right, all of that's a consideration and why I think this house needs to come down at least 33%.
