Why can’t the legal owner call the electric and water companies and ask for a temporary shut off starting midnight tonight. Stop garbage pickup temporarily. Request police to drive by my home frequently while I am gone on vacation.
Watch for them to be gone and request locks all changed asap while I am there.
In many cases the electricity and water is already turned off. They don’t care. They will build a fire in the back yard or even in the house on a BBQ grill.
They crap all over the place...................
