Investors - How Do You Track Your Properties?

[Steven Thoma]

Investors, and in particular those that do *not* manage their properties - how do you track your properties?  Is there a program or software that allows you to easily observe all the properties in your portfolio, as well as their details?  Perhaps displaying it in a format like a TD Ameritrade or other investing site.  I know there are many property management programs available, but I feel these are geared more toward operating the properties rather than tracking a portfolio.  Some of the things I'd like it to do/keep track of:

-Track purchase price, details of any loans, and current equity in the property as well as total portfolio equity

-Track current and past rents for properties

-Track total ROI for individual properties, as well as entire portfolio

-Track expenses, be able to upload receipts, bills, etc

Any suggestions are greatly appreciated.  Thanks!
