Termite damage during inspection

[Allison W Gammon]

Hi, I am purchasing my first 3 family which I plan to owner occupy.  The inspector found previous termite damage at the base of one of the exterior support columns.  I do not know how much this will be to fix or how much of a problem it is.  I am wondering if I should request a decrease in price or something because of this issue or a seller's credit to repair it?  I am attaching pics of the damage and of the exterior of the house.  The damage is at the base of the middle column.  Is this not a big deal or should I try to get my agent to ask for something?  House is about 130 years old, if that makes a difference.  Thanks!
