Baltimore tax lien investing-- what are the winners bidding?

[Nevin Young]

I am curious as to whether anyone can give some insight on what the winners are bidding recently in Baltimore tax lien sales. I want to participate this year, but I have only done live auctions before. Obviously I don't want to pay 100 dollars to register, research a hundred properties, and then get skunked because my bids are too low. Neither do I want to bid too high and not be able to foreclose profitably. Can anyone give some insight as to how far into "high bid premium" territory Baltimore tax lien investors are generally bidding?
