The property taxes are significantly lower, so it improves your cash flow, without changing the factors of the deal.Good luck!

I've had some good tenets and bad ones but I'm always looking to improve my processes, my homes, and of course my pockets.   :-)I usually perform my own renovations and snake my own toilets if possible.
