Plus mls dues, association dues, electronic lockbox access, e&o insurance.All these costs are on the rise too.

I would estimate it would cost 75-100K just to make this property liveable. 

Both of them are by the bedroom and this new one I just completed a master bedroom build added on to the back of the house with a private entrance for myself so I’m currently renting out the other 3 beds.Which cost me thousands more than I expected due to contractors not performing like I had expected etc etc. 

This is before you add any capex to your cost basis.

Fire suppression, fire walls needed, Sewer/Water/bathrooms/electical breakout, etc  Determine cost effectiveness.  

Was able to have the seller pay all closing cost and fees (over $25,000) How did you find this deal and how did you negotiate it?

I don't think the park has any effect on appreciation and certainly not 10 miles away. 

But the refi will likely cost you $3,000 - $5,000 - so there goes a good chunk of change that maybe you can refi into the loan... but it is really just a hit on equity.   

Monthly rent is $750, so I'm wondering if the costs/time/stress of eviction are worth pursuing if an option is to just tell him I need him out in 30 days.

I estimate cleaning costs/charges based on the number of bedrooms and bathrooms.
