I collected a bunch of stuff in the past and I have since put them in the archive after seeing my idol such as BD posting junk like S4V and no 75/25 split, etc. But I remember that there is a guy named TJ (where is he now by the way) who bought a subscription to something and see that these mortgage loans belonged to WMI and not WMB. You can also ask Justice, a respectful poster, about this.
Now if we don't have record that the LT trustee manage these DST but we have record that the loans belonged to WMI, is it sufficient? Because unless we have insider news, there is no way of getting info about who manages these DST.
