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. 

Age of furnace/boiler?

What I am basically trying to get to is where is a good starting point for someone my age that is very ambitious?

@Brian H.Some of the questions you're asking are heavily dependent on your facts, circumstances and goals and should be directed to your CPA and/or financial advisor.You didn't state whether or not you're married or single or your age... 

As for the age of the building you are correct in stating things are reaching the end of there age. 

Some of those variables are the size of the park, number of vacant spaces, number of POHs, number of vacant POHs, number of MH spaces, number of RV spaces, the park amenities, the age of the park, underground infrastructure age and condition, park location, size of the market, value of SFR in the market, water or well, sewer or septic, other utility sources and whether or not they are direct billed, deferred maintenance, cost of management, and more.However, there is a basic "back of the napkin" evaluation that will usually tell you if the deal is worth a closer look.
