Do Investors pay 2 times the property taxes in Indianapolis?

[Eddie Knoell]

Hello Bigger Pockets, 

I am interested in purchasing a single family residence investment property in Indianapolis and I was told by the real estate agent that if I purchase it as an investment property that the property taxes would double. They mentioned that primary residence owners get a tax exception. The property is in Marion county which covers the whole city. I have never heard of this before. Is this accurate?
