Done and done and done
Some last emails came through from the cult co-op app this morning (including one cancelling the reservation for the loading dock for move in later this month - I want to know more! but really I don't), then the app gave me the "you don't belong here" error message mid-day, so I deleted it, and the associated bookmark for the web site from my computer's browser. The check from the settlement company arrived and was promptly deposited through the bank's app. I checked the former mortgage company and got the best message screen stating that "this loan is inactive". So done, and done, and done. Hallelujah.
