Every tax deed state handle's their tax sales differently and every state has different rules and standards. When I got started, I made a list of tax deed states nearest me. Then I started calling different county courthouses and asked for the assessors office, then asked when they usually hold the auctions, then ask how well attended it is, how many properties make it to the auction usually, what to expect after the sale, and most of the time the person on the other end of the call has a lot of great info for me to get started, some states that I called the person at the courthouse will even warn you if junior liens carry over to you with the property. So after I weeded out the less attractive states, I then called multiple real estate attorneys (some I had to pay just for a 30 minute phone call, but it was worth it). Have a thorough list a questions ready for them, and after about a week or two of talking with different lawyers in the states you feel are more lucrative, you will know exactly what states will be best for you. Tax auctions are pretty entertaining too when held on the courthouse steps, I've been to a few where the auctioneer gets heckled and other investors trash talking while you bid. Best of luck and welcome to Tax Sales.
