Property Evaluator is the most powerful real estate analysis software available for the Mac. After entering some information about the property, you can view financial projections that show you a true apples-to-apples comparison between properties.
It takes the guesswork out of finding the best deal. You can also save a PDF of the financial projections to email to your clients, lenders, or investment partners.
Note: The downloadable demo is at 5.2. The version available for purchase on the Mac App Store is version 5.4.4.
