In Pennsylvania, at least, sellers don't have to reveal that a murder or suicide had occurred in the house. Last July, the PA Supreme Court ruled that was not a material defect. Here is the coverage.
However, that doesn't mean the house will sell. Often potential buyers who come to see the property don't even get beyond a few rooms. They "feel" something is very wrong.
That something could be what are known as "earthbound spirits." Last night at the Tamara Spiritual Center, Tucson, Arizona, the head Karen Bock explained that earthbound spirits have already died but refuse to "pass over" from the physical world to that next dimension.
The reasons for that could range from fear of the unknown to misformation. Regarding the latter, one female was waiting for her lover to return so that they could marry. Over the years she had become embittered when he didn't show up. Therefore, she threw temper tantrums in the house.
A "cleanser," that is an expert who manages spirit presences, explained to her that the man had died. That's why he hadn't joined her. But she could join him if she allowed herself to walk into the light. That she did. The house sold.
Lawyers can help those in the real estate loop, ranging from agents to property owners. First they could clue them in on the possibility that the house may be inhabited by earthbound spirits. If this information is accepted, then they could research the cleansing process. Or they can hire an expert aka ghostbuster to accomplish this.
In my Victorian house in Norwalk, Connecticut, I and my animal companions would find ourselves tossed down the stairs. Brick, New Jersey psychic Mary Ann Kremer gave me the instruction on a cleansing. Those did the trick.
