Most people may be rationalists, but in reality we all feel uneasy when we see a property that has a reputation of being haunted, or even left for a long time period to either sell or rent out. Indeed, in many Countries the fact a property is reputed to be "haunted" could leave that property hard to rent, and impossible to sell.
Business Owners and Investors should be extremely wary of the reputation of the building they move into, and research the buildings reputation, and history. This is very true in many Asian Countries-were the fact a property is reputed to be "haunted" could ruin a business.
Often rational people forget that a degree of people do believe in the supernatural, and would not dream of purchasing or renting a haunted property, unless the place was offered at a bargain price.
In Indonesia, and China were the belief in spirits is still very strong, even amongst the Western-educated elite, who run the Country.
Hotel owners and home owners have seen their businesses face ruination, as rumors of "Ghosts," often scare people away from the property.This is also true in Germany and Eastern Europe, that in essence are scientific states, but in reality are littered with cheap unwanted properties, that no-one wants to live in because of rumors of being haunted.
Some savvy business and home owners create business by advertising the fact that a building is haunted, attracting curious guests, and customers. But outwardly in today's scientific World, most people are reluctant to admit to believing in "spirits," even if they would never rent or purchase a property that's reputed to be haunted.
Often we leave rationality behind, but if you are looking for a property or a business, research its history before you decide to move in.
Otherwise like the Owner before you, you could easily fall into a trap of owning or renting a "bad" property that can ruin your financial future.
