Alabama Tax Liens: What fees to charge?

[Brandon Watson]

I recently purchased a tax lien from the state of Alabama. The tax sale date is 5/23/2017. I went by the property multiple times. There was no indication of someone living at the property while waiting to the certificate. Once I finally received the certificate, I went by and still no sign of someone living there. Power company said the power had been off for three months. I had a locksmith come out. Once inside, i notice furniture is still all over the house. I go ahead and replace the door lock since the locksmith basically just ripped the lock off. I go back the next day and there is a note saying "please don't remove items from house, i want to redeem." Though I was hoping to use the as rental property, i know i have to allow them to redeem.. since all i had done was remove and replace the locks, legally what can i charge on top of the taxes owed for the owner to redeem?
