Cleaning out units, I plan to pay a cleaning company for turnover and pass on any extra fees for cleaning out units (like left furniture/food etc.) onto the tenants via a deduction in security deposit. 

In addition I paid my parents a contractor management fee which I do include in the costs.Now I know for tax purposes they will not include my personal travel (I already deducted that as on my sched C), I know none of the CC interest or fee's would be deductible anywhere, but regardless I plan to include them on the gross. 

There is closing cost which you have to deduct before the lender will pay off your credit card.

Am I able to deduct the home equity loan interest for 2018 federal tax return?

Also, are broker's paying themselves commission if they do purchase/sell a house or are they just deducting it from the purchase price as the commission is taxable?

The buy and hold would be great as it would generate cash flow plus additional tax deductions.

She never paid it, so obviously it was deducted from her security at move-out.

I Found this on a mortgage Calculator website, if this is true...What would be our new strategy to counter the Thousands of Dollars in Interest payments we can no longer deduct ?

This is based on my typical deductions every year - regardless of my triplex income. 

It doesn’t appear like you are making the necessary deductions for taxes, insurance, maintenance, CapEx, vacancies, and property management.
