First Lien Position

[Luke M.]

I've come up with a strategy to target a market with potential for massive growth in the next few years, and purchase first-position tax liens on vacant lots properly zoned for multi-family. I know it is a bit of a stretch, but I'm hoping to eventually acquire one that doesn't get paid off. Since taxes are low in the area, it shouldn't cost too much to pick up a few of these, and even cover the subsequent year's liens until the redemption period has closed. This county's auction is online.

Here's my question: Is there a way to determine if this is the first year that the property is behind on taxes, so I can ensure I get first position? I don't have a relationship with a title company in the area, and I'll be doing this from a distance.
