Their communication can be described at best as mechanical.

In the Houston area, most of my foreclosure have come to me from failure to pay HOA dues or comply with HOA, or probate.

Those failures are  more negligent than a PM allowing a guest who paid with expectation to stay at the house to remain there in the middle of winter when they arrived on a Friday evening as you described.For now you will have to rely upon insurance, I don't believe the PM acted unreasonably given the circumstances.

As for the first, yes we'd be able to do that (for example, replacing a water heater which is the mechanical that's closest to the end of its useful life).

ONLY purchase training if its with funds you can afford to lose because of the failure rate.making connections is important and where success can come from.

This means you can sell, lease, or pass on the property as you see fit, just like any other property owner.Full Ownership RightsYou have the same rights as a Mexican property owner, including the ability to sell, lease, transfer, or mortgage the propertyLegal SecurityThe Bank Trust is a well-established legal mechanism in Mexico, ensuring your investment is secure and protected under Mexican law.Renewable TermsThe trust is set up for 50 years and can be renewed indefinitely, allowing you and future generations to maintain control over the property.Estate PlanningThe trust makes it easier to pass the property on to heirs, simplifying the inheritance process and reducing potential legal complications.Although the process might initially seem complex, it is entirely managed and supervised by a reputable banking entity.

I would like to know more about ways to use OPM  The only way to determine if the home is going to cost you a lot down the road is by determining the age of the mechanical systems & if the structure of the home is sound. 

Not only low-flow, the flushing mechanism reduces the likelihood of clogs.  

@Jay Chung If the mechanicals for the duplex are in the basement it may be better not to give the tenants access.

That could totally be based on execution failure, but for us, it just wasn't a good fit.
