Does it matter how old a house is if its completely rehabbed?

[Brandon Low]

As the title says... Does it matter how old a house is if it has been completely rehabbed? 

For example, lets say we have 2 houses:

House #1: Built in 1950 but has all major items rehabbed like roof, plumbing, electrical, HVAC, flooring, kitchen/bathrooms, etc...

House #2: Built in 1990 but has not been updated since.

Would the older house still be more prone to more maintenance and repair even though it has been rehabbed and updated?

I've lived in 3 different homes in the last 25 years, all dating before 1950. I've never had any structural issues, and find the older homes to be very solid, i.e. They have good bones. So I am all for older homes and think that when rehabbed properly they are just as sound, or more sound than homes built in the 90's.
