Property taxes in texas

[Steve S.]

I'm curious if there's any tools or obvious formulas that could help me understand turner impact of property taxes in a rental property I may buy. 

As an easy example, let's assume property tax rates are (2% - that would be nice ;)) and the property is appraised at $200,000. 

That means property tax would be $4,000 for the year. 

If I'm in the 28% tax bracket, how much of that could I write off and is there a general ratio or percentage that could be applied for quick back of envelope math?

I'm thinking, although I'd have to pay $4,000 that I could write off some of that in a way that my net outlay wouldn't be $4,000 when all is said and done. 

Is that correct or is it just interest that could have a net positive impact?

Do most of y'all own your rentals through a corporation you form?  How important are these considerations when purchasing rentals?
