Obviously you are willing to settle for less than $1250 otherwise you wouldn't be offering it for sale.
but 'settle for less' comes with strings attached.
the other aspect to it is timing.
faster money is more valuable money.
i.e. getting your hands on $400 within the next 10 minutes is probably preferable to getting $600 within 7 days or $900 within a month, or the full $1250 within nobody-really-knows-how-long.
i'd also settle for less than i'm currently owed, but that would also come with time-related provisions attached. otherwise i'll just wait it out.
