state that offer OTC tax liens and deed

[Maynhia Stott]

Hello, I'm new to tax liens and have pinned downed my goals for tax liens investment. I would like to concentrate on OTC liens and deed. I researched states that offer OTC with high interest rates. Can you anyone tell me if I'm missing any? The states I have so far are Alabama, Colorado, Florida, Maryland, Michigan, Mississippi, Montana, West Virginia, Oklahoma, Arkansas. 

Please correct me if I'm wrong on the states mentioned above as well. Thank you
