Multi-year portfolio projections spreadsheet

[Carlson Driver]

I came across this cool spreadsheet by Roofstock but I cannot find it on their website. 

What is cool about this spreadsheet is that it allows you to project out what your overall real estate portfolio would look like as you increase the number of doors.

Does anyone know whether this spreadsheet is downloadable somewhere? Or any other similar spreadsheet that allows me to project out what my portfolio could look like over the years?
