This might include: homeowners association dues; whether or not work done on the house meets local building codes and permits requirements; the presence of any neighborhood nuisances or noises which a prospective buyer might not notice, such as a dog that barks every night or poor TV reception; any death within three years on the property; and any restrictions on the use of the property, such as zoning ordinances or association rules.
It is wise to check your state's disclosure rules prior to a home purchase.
