Lots of schedule Es I can not read or understand.I obviously know my rent "income" and my costs (especially since I make NO positive cash flow money on it and mostly loose money (last year I lost "only" -$1175) so i want to know what i made in appreciation versus how much I lost per year for the past 20 years. 

College educated. 180k year income.

What is a reasonable way to apply an estimated tax benefit of the interest deduction vs. the tax on increased positive cash flow vs. invested income? 

At some point for DTI (Debt to Income Ratio) purposes, I also had to provide rent roll.

Our combined income is, on average, around $230,000 a year.

- Do I need a different insurance than the residential income property insurance?
