Lowering property taxes

[Karen Higgins]

I'm looking for input on lowering property taxes in MN.  We purchased 14 units a few months ago, that was bank owned.  The valuation used for the property taxes is close to 1M, and our purchase price was $600K.  I've spoke with the county assessor, and am being told, that they most likely will not lower the taxes because they do not take into account sale prices of foreclosure properties.  Has anyone else run into this?  Do you think it is worth it for me to set up a new evaluation?  Any input would be appreciated.  Thanks!!
