I just completed an article on the best real estate accounting software for small businesses. It won’t be published for another 6 weeks but I believe the best software to manage both of your businesses and your personal finances would be QuickBooks Desktop Pro or Premier. While out the box QuickBooks is not customized for a real estate business, it can definitely be customized to meet your needs. In addition, you can set up as many company files with QuickBooks desktop as you need for no additional cost. I also recommend that you set up a company file to manage your personal finances.
Here is a recent article that includes in detail the cost and features of the QuickBooks Desktop product line. You should go with QuickBooks Pro or Premier. Enterprise is probably too much for your business needs and the Accountant version is for bookkeepers and accountants who support small business clients.
