100 year old homes

[Joe Capobianco]

i have been searching for 2 family homes and realized most of them are pushing 90-100+ years old. i was wondering from other investors what your experiences are with homes of that age? i've already looked into a couple but didn't get further then inspection due to foundation issues. the homes are sagging in the center. should i keep away from homes this old? should i find a deal good enough that this can be resolved with a structural engineers help?
