Recommendations for a simple property management tool/software

[Shannon Brill]

Anyone have recommendations for a simple property management tool/software for REIs to keep track of multiple units??? I currently have one unit and looking to expand in the near future, but I want to have a management tool in place now to stay organized. I currently have a property management team so I don't need all the bells and whistles (i.e. tenant screening, online payment, etc.) that a lot of the management tools offer. Thanks in advance!
