Overcoming objections and pushing for a close just don't feel right to me. 

My investment originally was schedule to pay my principle back and first installment of gain within 4 years.

All LL expenses would include PITI (Principle, interest, taxes, and insurance), maintenance/cap expenses, Property Management (allocate for it even if you plan to self manage), vacancy, and miscellaneous. 

That’s when I decided to make life decisions based on my principles .

The only one I would object to is the 45 day use fo the property.

Expenses - Principle, Interest, Taxes, Insurance, HOA fees5.  

The objective of the meeting will be to see if any these expenses (losses) could have been avoided or did I just have bad luck this year.

Investors have a clear scope of work, a budget and a need to build a team who can execute on specific objectives- management, repairs, multi-faceted financing strategies.

So even though your loan payments reduce your income and the numerator decreases, the denominator decreasing by a factor of five boots your COC calculation.What Todd said, except you can't use the principle reduction from the loan payments as cash income since the reduction isn't income...and it isn't in the form of cash anyway. 

This is a highly subjective and personal question that I think has more to do with your comfort and feelings than an objective numbers response.
