Excel Training Recommendations for Residential Investors?

[Grant Zaharis]

Hi I am looking for referrals to courses or programs to help level up my day to day operations in excel. 

I currently have QB and a bookkeeper so this would be skill up related to all of my residential buy and hold investments, flips, wholesale and general contracting operations. 

The BP calculators are great to a point but im looking for the skills to develop my own excel templates and programs that fit my financing structures in place. 

Thanks in advance!
