Buying Vacant Tax Deed Land in Alabama

[Ebony King]

Hello, I am a new investor and I have decided that starting off, for now, I'd like to invest in only vacant land. Specifically, I am looking at land within subdivisions or decent areas of town that people would probably like to eventually build homes on. I have a few questions and would love to get some insight:

1. If I purchase the land from the state, can I immediately sell it to someone perhaps for a fraction of what it's worth?

2. Is quiet title action necessary for vacant land?

3. If it is necessary, what do I need to do to prove possession besides cutting the grass, clearing shrubbery, etc.?

4.  If the tax deed is reallllllyyyy old, is there anything "special" that would apply?

Any and all help is greatly appreciated! Thank you so very much!
