Petition Property Taxes as Investor?

[Francis Rusnak]

Cash flow in Chicago and South 'Burbs is great. But the biggest killer is the redic property taxes.

There are two single family houses we're looking at now; we'll be allin for under 50k on each with purchase and rehab. Rent will be around 1400/month. 

BUT property taxes are currently 4.5 and 5.5k for each!

There is a loophole that allows landlords to make tenants legally responsible (in their lease) for property taxes through the payment of their rent. And this qualifies the landlord for the homestead exemption. 

Have landlords used this or ANY other tactics to lower the property taxes?
