@Deborah Repaskey Buying a house that is 70 years old is getting better every year, one of the biggest issues with older homes tends to be knob and tube wiring or plumbing that isn't copper, both of these really started to be changed to modern standards starting in the 50s so that decade can sometimes be a mixed bag but those are going to be your primary concern unless someone hasn't replaced a major system like a roof in 70 years.
