This
piece of worthless garbage (the SPIS) is nothing more than a smoke - screen vehicle to be adopted by sellers (whether honest or dishonest in nature, not to mention their ignorance
of the state
of their own properties) in pursuit
of facilitating smooth sales whereby sales would be more difficult to achieve without the supposed «feel good» SPIS boxes being initialed «yes» or «no», as the case may be, reflecting the negative reality, or positive unreality, as the case may be,
of the condition / hidden defects
of the said listed properties.
