Since an executor/personal representative has not been appointed by the court and no Trust is in place, there is no one who can sign for the deceased. 

Also the next time the tenant starts behaving unprofessionally, simply ask them to call you back once they've calmed down and hang up on them...or just hang up on them. 

It depends on how it’s approached and why.As a start, you can skip trace the property.

It sounds like you just started your RE journey.

A friend was renting a place in Denver, and just purchased a home.

I am wanting to start investing in STR acquiring or developing the real estate.

What systems and processes do investors have set in place for the following?

From my experience Indianapolis and the surrounding area is a great place for flips and some rentals.

I don't really expect the property to cash flow, I realize that it's an expensive place to operate a STR and that on-island management is necessary by Hawaii law, but I'd like to be able to cover most of my mortgage and expenses after putting 30-40% down.
