A: The answer in this case is that the artist's death will have little impact on the value of your art. Many people believe that prices skyrocket when artists die, but that's a myth perpetrated primarily by dealers who say anything to make sales.
An artist's death significantly impacts his price structure only when he's relatively famous, his work is expensive, he's in demand and collectible, and most importantly, he dies unexpectedly. As evidenced in the months immediately following the deaths of Warhol and Basquiat, for example, their markets went temporarily insane before gradually settling back to normal. Dealers and collectors were caught off guard, everyone scrambled for the art, a sort of buying panic set in, and prices spiked in the upward direction. When an artist dies of old age, however, all market changes have taken place slowly, sensibly, and in an orderly fashion. Death comes as no surprise to anyone and consequently, prices remain relatively steady.
