How Do Taxes Affect Real Estate Deals?

[Aliyyah Carter]

I'm curious about the role property taxes play in determining whether a deal is good. I've noticed that properties in Delaware County are often more attractive than those in Philadelphia, but the property taxes are quite different. 

When evaluating potential real estate deals in Philadelphia, Delaware County, or Montgomery County, how do the differences in property tax rates impact the overall assessment of whether a deal is financially sound? To what extent do property taxes play a role in determining the attractiveness of one location over the other?
