Sorry to be so harsh but your setting yourself up for a lot of frustration with this property.

(harsh I know, but this is truth..) 

Forgive me, this will sound harsh though text.

It will be a tad harsh, however it's better you hear it now. 

@Christopher Lane This may sound harsh but this is the harsh reality of life.

while that is an awakening for you, its a chance to feed you some knowledge in this January 1, 2019 about mobile homes and the moving parts within them.1st of all, MHPs in CA are a major pain, and analysis paralysis isnt always a bad thing, in this case run from that deal. here is why........that mobile home is  POS.2ndly you i can tell from the info you posted that you dont know about Dodd-Frank or the Safe Act of 2009 which is harsh laws that come down on investors carrying financing to unscrupulous low income buyers of would be mobile homes in parks or on land.

Many are clueless on just basic principles of being in the people-business.A laundry list:Poor communicationPoor responsivenessPoor market understandingPoor inventory awarenessPoor etiquettePoor negotiation skillsPoor contractual understandingPoor transactional/procedural understandingPoor client management (like the nuances with 1st-time buyers)Part-timer/not committedInability to understand client needs (especially prevalent for investor clients)LazyRudeAnd the harsh list goes on....
