@JD Martin Thank you for the reply, I can def take the criticism :) I will say that I am a first time home buyer so I am learning a lot.Regarding the pests, you're right, I can take care of those.The building is much older than the heating unit, I assumed that the appraisal for the home would be affected by the state of the garage (both roof & walls), I was not aware I should've considered those before placing an offer, I was under the impression that I did not have to identify these things in a walk through and they would be discussed during inspection/appraisal/negotiations.About the smoke/CO alarms, this is not a major deal, but local law states if they don't have working smoke/CO alarms they have to pay me $250/unit.

Just understand you're dealing with people who have different customs, language, time zone and priorities than us.I've found video tutorials and painfully detailed explanations to be critical to success. 

The most critical component is reliable boots on the ground.

There are so many variables in MH/RV parks that can wildly effect valuation, it is critical that you not only understand them, but you take a conservative approach to expectations of the upside as well.

@Kyle Eckertas @Jack Martin mentioned you must not skip over this critical step.

Finding trustworthy property managers and vendors is critical.  

Especially when you are first starting out, your ability to visit the park in person will be critical.  

If you are doing a value add, make sure that your manager can handle a value add like the one you are doing.The other critical thing with managers is to be sure they know your expectations.

Property manager- This was critical in my first purchase because I didn't visit the property.

Your and their continued education by experienced teachers is critical.
