Documented.Example;  snow or ice removal procedures, documentation of rental refusals, eviction procedures, auction procedures, abandoned property procedures, carbon monoxide or fire alarm systems, chimney cleaning, grills in wood decks, etc.Even if you get sued and lose, the judgement will be less with operating procedures.

Taking an empty site or reimagining an existing/abandoned building into housing or mixed use is most definitely a goal of mine.
