Real Estate Calculator – Real Estate Investing is a free real estate calculator app that can help you evaluate a property’s profitability and determine whether it’s a good deal. You can save and load as many properties as you want, and you can compare properties between each other to see which one is the best deal. The app calculates everything you need to know, so you don’t have to do the math by yourself. If you want to find out what a property is worth, you can easily use this app to get an estimate of its value. You can also use it to calculate your monthly mortgage payment, your profit after deducting the mortgage payment, and the property’s net income.
