@Tiarai Fields I'm sorry it has taken so long to respond...I work in Education and we are busy with Testing Season right now...amongst the Holidays, etc...
My journey has taught me that Tax Lien investing is kind of long and drawn out...
Here is my process:
Download the PDF for the County you want to invest in. You can find the list for all Alabama Counties here.
When I see a property on the list I am interested in, I then open the window for the County Tax Assessor Parcel Search and search for more information...such as property address, etc. The Tax Assessor Parcel Search for Jefferson County can be found here.
When I find something I am interested in bidding on, I submit my bid at the ADOR Bid site. It can be found here.
Don't expect a reply soon. Some replies will be sent within a week, and some I am still waiting on after 6 months. It is just something that takes patience.
I recommend reading as much information as you can on BP...there are many excellent, top notch investors on here who offer great advice on here...much better than I. I especially recommend following @Denise Evans. She is a TREMENDOUS resource! One of her writings I have learned from is from this post. I have learned much from this source alone.
