Project Description:
I need a small program to post and calculate my revenues from several apartments I own. I like the simplicity of my table (currently a simple word type program) I mostly do short term rentals, and just plug in my data. I am interested in the following data:

1. My Monthly & Yearly revenues per apt, and in total.
2. Availability dates in each apt.

See my current program I use:
