I just got your program in December.

I have 15 units. - 2 single dwellings, - 2 duplexes, - 1 4plex, - Victorian with 5 units.

I currently use Excel documents to keep track of stuff. tax season is not fun for me or my CPA.

 I agree, this will make your tax time a breeze.. the hardest part is your transition and getting all set up properly

Would it make sense for me to input this year's stuff from January to December. - of course for 2017, but I assume you mean for 2016?
