1.) they expire after being listed for 6 or so days, this is an issue because the note never sold, so it will totally mess up your datat
2.) they were sold, but there isn't away to distinguish from above
3.) they were removed by the seller, wow I way over priced that note, let me relist it
4.) they were removed by LC for getting a payment, which you only know about if you were either the buyer or the seller
That's correct. IR cannot distinguish between a note getting sold and one that a seller cancelled for whatever reason.
Here are some tips to help identify the sales from the BS. I'll address the points above.
#1 and #2 If the note shows up in IR as sold, but was listed for 6 days, count on it being expired. A sold note will generally have a listing time of 0 to 5 days.
#3 The seller removed the listing. Another easy discovery. Just look back up to the list of notes for sale and see if that one is relisted.
4.) "Canceled for Payment." This is simple also. Unless there was only 1 note for sale, all notes expire the exact, same time. So, if you see like 5, 7,or 15 notes that all appeared to have been sold on the same, exact day, that's the day they were all cancelled for payment.
Another way to confirm this is that you will see many of the same notes relisted once they come out of their payment process.
It takes a little practice. However, once you get the hang of working with IR, you'll be able to glance over that list of sold notes and know which ones were really sales without hardly thinking about it.
