I believe there is a basic tenet in the law that says that if a contract term is vague that it will be interpreted to favor the party that did NOT write the contract.

If that is the case you could make them the responsible party for the cameras without you having access but I would just remove and store until vacant if this is single family and let them take the risk. 

The language barrier was the most difficult piece in my experience but I also ran into legal issues where the party that defaulted on their contract was connected so there wasn’t much I could do to get what I was owed.

Generally, a simple refinance transaction should take no longer than 30 days or so assuming all parties operate smoothly together.

The important part is getting started.If you’re still feeling stuck, maybe try connecting with a mentor or someone who’s been through it.

@Vinessa EiseleInteresting negotiating skills.I have lenders who will allow seconds on DSCR loans, but the "seller financed" part is limited to 15%, whereas the borrower must bring at least 10% of their own funds to the deal. 

Every extortion attempt I have experienced in Baja has happened North of Ensenada.Beyond Ensenada are cool things like wineries (I do not drink wine), La Bufadora and its blow hole, great little fishing villages, Gurerro Negro and Scammons Lagoon (best whale watching on earth), San Pedro Martir (least visited forest region within a day of San Diego and has the twin Picacho del Diablo peaks and the national observatory), numerous Missions in various degrees of condition, hot springs, party towns (San Felipe), surf towns, snorkel/diving (anywhere in Sea of Cortex in Baja Sur), Sand Dunes (Baja races), etc.My worse theft south of Ensenada has been some bottled water.So the question is why Rosarito? 

This coinvestment is what mitigates the risk of the other party taking risks that could be a detriment to the investor.

Does a dead lawn due to lack of watering in addition to the lack of basic property security and reckless waste of utilities (AC and lights) constitute negligence/breach of duty on the property manager's part? I

The hard part is, agents/buyers understanding how to do that.
