@Matt Everling I have found that they want more like 40-50% down depending on type, age, etc....

My name is Jordan C (age 27).

Sounds like a triple win to me but I guess it’s your decision.If I was you I would like to see where the most people in your age group are living and start investing there.

People who are aged 55+ and have owned the property for a long time?

However in this electronic age maybe that does not have the impact it used to. 

Immediate repair no matter the age of the structure.Salt-damaged or pitted concrete?

If you'll post how many lots are occupied, what the lot rent is, what the market lot rent is (a guess even), the age of the homes (roughly), how many homes are park-owned, what the park-owned rent is, and how big the metro is, SF price, and 3 BR apartment (pull from Bestplaces) --  BUT DO NOT POST THE CITY OR STATE SO NOBODY KNOWS WHERE THE DEAL IS -- I'll give you a quick evaluation right here.

Something like a GE Zoneline, maybe? 

> Also, always change the evaporator coil (indoor coil) when installing the new condensing unit (outdoor unit)This part I agree with, especially if you're replacing either of those because they have failed of old age, or if they were very old (20+ years) and suffered some external trauma, which are probably the most common conditions.If somebody steals the outdoor unit for the metal, or a car skids through the yard and takes out the outdoor unit, or someone tries to use a 12" long drill bit to hang a picture and puts a hole in the evaporator coil, that's IMHO a little different. 

On mobiles, the age means a lot, when was it built?
