    The ROI calculator from Opes has really changed how I invest. It's easy to see how different properties stack up against each other, which helps a lot when deciding where to invest. It's a big time saver and really helps me understand my investments better.

    I suggest the Opes ROI Calculator to everyone looking into buying property. The sheets where you enter your info and see the results are very clear and give you all the details you need to know about your potential profits. I have been using it for the past few years and don't know what I'd do without it.
