These tax credit servicer/admins are more specialized and they are working with specific projects so investors will have little interaction with them.I was a Commissioner of our large PHA here in Springfield, so that's the reason for my background on the topic, being an administrator/commissioner is an appointed position by the local government entity that "sponsors" the PHA, in my case appointed by the Mayor of Springfield.
