Buy and Hold with Older Homes

[Max H.]

I live in the Philadelphia area where the housing stock is pretty old. A lot of the homes are 100+ years old now. I'm 28 and thinking of buying a triplex that was built in 1910, I would ideally hold this property for the next 15-20 years. My concern is by the time I am ready to sell that the home will be almost 130 years old and the market for a home that old will be slim. 

The house has updated plumbing, electric, roof, windows, and all that but does anyone see an issue with a buy and hold strategy on older homes?
