I was thinking because of my age that I wanted to pay these off at some point, 15 years or so to get more income when I retire however the flip side and feeling I'm getting from investors is more properties less down more cash flow now and not worry about paying things off. 

Parden my ignorance and lack of education but my concern is if I had to evict would a judge being there is a child under the age of 10 wait till spring to evict in the state of PA?

That is were everyone has told me to start and is the most logical option for people our age.

Listen to Gary Vaynerchuk talk about the value of age and long term focus on one goal. 

The age of the property shouldn't make or break a deal but definitely something to consider when deciding what type of rental portfolio you'd like to build.

Hi @Max Schieble welcome to BP and congratulations for starting at an early age!

To quote @James WiseLandlord from Hellhttps://www.losaltosonline.com/news/sections/news/200-police-fire/60714-late-rent-prompts-eviction-by-invasionTenets from Hellhttps://www.cleveland19.com/2019/08/26/multiple-cleveland-families-evicted-building-apartment-tenants-call-move-controversial/Hard to believe in this day and age, especially in CA, the landlord would just gather up a  "posse" and physically throw someone out.   

This can of course vary 5% either way depending on owner paid utilities, services offered, age of the building, etc. 

At your age, just get some base hits under your belt, focus on your education.
