Indianapolis Veteran Tax Question

[Brandon Koser]

Sorry for the multitude of questions. Trying to understand Marion tax code as I just realized there MAY be a tax exemption available. 

Does an investor who is a veteran at 80% disability get any property tax deduction and if so how much? 

Does it require it to be a primary residence or can rental properties qualify? 

Is there a limit on the number of properties? 

If a property is placed into an LLC-S that is owned by the veteran does that still qualify for an exemption?

I doubt it, but could an exemption be applied retroactively? (One property was primary residence for a few years, so there's that too)

Thanks all
