Many people think this is the "best" way to make money in real estate due to many late night info-mercials, however, it is a long process. Dont just limit yourself to tax sales looking for a deal. Look at short sales, bank foreclosure, sheriff's auctions, and REO properties as well. find an agent that is good at working with investors and can help you find deals and bring deals to you. I have a handful of investors that I work with and I bring deals to them and they are making a lot of money investing in real estate, but they do not just look at one avenue. Ohio is not and never will be a "get rich quick in real estate." It can be very lucrative, but will never be a lottery jackpot in a short time. If you are in it for the long haul, it can be great!
