Is renting really cheaper than owning in Kennesaw right now?

Whether renting is cheaper than owning a specific Kennesaw home right now depends on the actual rent for a comparable property against the actual mortgage payment, taxes, and insurance for that home, not a general rule that applies citywide. Rental rates and home prices move somewhat independently of each other, so the comparison has to be run property by property rather than assumed. A side-by-side comparison using real numbers for a specific address gives you an honest answer. Joel Boss can build that comparison for a Kennesaw property you are actually considering.
