Tax Appeal - Increase after hearing?

[Mike Kalob]

I'm considering tax appealing 3 of my properties; 2 seem very high given my low [foreclosure] purchase price, but 1 can go either way since the neighborhood is gentrifying for that one.

Would I be shooting myself in the foot if I try and appeal the last property?  The city hasn't had a reassessment in years and is happy so long as taxes get paid.  If I try and appeal, and find out my taxes are low given this part of town is gentrifying, could they actually INCREASE my property tax?  Advanced thanks.
