Tax certificate property

[Charles Richards]

I am in the process of buying a tax certificate from a real estate company in Birmingham AL. I am trying to find out how I can legally take possession of the property. There is currently someone living in the house and I'm assuming it is the current owner. I am still waiting for the certificate to come in it should be here in a few weeks. So I am trying to get all the information I can so I know what to do next.

so my questions are...

1. How do I go about taking possession of the property

2. Am I legally able to rent the property out after taking possession

3. After the 3yr time period and I receive the tax deed is it still possible to have a redemption be viled against the property
