Obviously, there is functional obsolescence, and exposed knob and tube can be a factor (although enclosed in walls and ceilings is generally fine, attics and basements are your issues, generally).In first reading, I am less concerned about the property age (every property I own was built between 1914 and 1952), but more with the 10% assumption on vacancy, capex, repairs and management.
