Value of a tax certificate

[Brooke Boyd]

I am wanting to know the value of my tax certificate. I purchased for 18k in back taxes. There is a right of redemption here in AL. There is a 4k lien. The property is in very bad condition. The title will need to be cleared. There is a trust made up of several doctors and lawyers that could easily redeem the property when notified through the quiet title process. So as of today, what can I do do find out the value of my tax certificate? Or is it worth what I paid for it?
