When we talk about a "stigmatized property", we mean a house or land that people believe has something bad or scary attached to it, but it might not have anything to do with the house itself.
For example, it could be a house where someone died, or where there was a scary or violent crime. It might also be a house that people think is haunted or cursed, even though there's no actual evidence of that.
Because of these beliefs, some people might feel uncomfortable buying or living in that house, even if it's perfectly safe and there's nothing wrong with it. This can make it harder to sell, and it might mean that the price is lower than it would be for other houses in the same area.
But it's important to remember that a stigmatized property isn't necessarily dangerous or bad in any way. It's just that some people might have certain superstitions or beliefs that make them nervous about it. So if you're thinking of buying a house that's been stigmatized, it's important to do your research and make sure you're comfortable with the history of the property.
