Good question. Is one of the Portfolio accounts related to it? Maybe combined 2 together? You do know once you pay Portfolio they will remove their accounts off your reports.
Well thats good news. Congrats on getting them all paid off and poofed off your reports soon. Dont kick a gift horse in the mouth. Take it while you can. And welcome to the forums BTW.
Keep us updated on how its going. It may help others in the same situation. Good Luck!
