What have been your experiences with Skip tracking software.... which do you feel has the best features for the most value for the money?

@Caleb Genry yet another request for your time tracking sheet if you don't mind. 

As far as home office no longer being an IRS "red flag" I guaranty that if you put a home office deduction on a personal return on Turbo Tax it will move their audit risk needle.

A sophisticated investor will also typically ask for the entire claimed track record and then run it through the wringer.

Start with the address and details about the rental.Create a section for tracking the lease information.

My question is what have people used with success to best track their time/investments over the year?

This is a mixed-use property with retail, office, commercial, residential, and hospitality use.

.- One master key opens every door- We go 3 levels under our master, so we can submaster 2-4 unit houses and apartment buildings- Don't need a costly and difficult to secure & track keybox.

Is there a way to passively track mortgage rates on 5+ residential apartment buildings?   

@Stephen Schroeder it would be fantastic for PMCs to be able to charge owners as you describe, as owners might then truly appreciate everything their PMC does for them.Unfortunately, no one has yet devised how to practically do this.So, PMCs' absorb most office & admin expenses and are compensated for them via the monthly fees they charge their clients.
