@Caryn FischerI agree with Jaron, you should definitely have a consultation with your tax accountant and/or financial planner before you do anything. 

Do you hold any financial advisor certifications?  

By the time I retire, I want to have enough rental properties to have financial independence to enjoy my hobbies and enjoy spending time with my family and watch my children grow up.

Prioritize your financial stability.

At one point I talked to my financially advisor and he said that it would be smart for me to open a HELOC on the property, but not draw from it, except in the case of emergencies.  

Prioritize your financial stability.

A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant specializing in real estate taxation, business taxation, financial planning and tax planning.Consider working with your accountant remotely to expand your options.I would also recommend looking for an accountant willing to work with you throughout the year.

Once again, I had to ask my family for financial support—a daunting task after the first loss.

Through proactive maintenance, efficient tenant placement, and careful financial management, I optimized rental income and ensured a steady cash flow.

Your taxes are none of the ex wife's business and this would seem to address your concerns.I would also put her on notice that future requests for financial discovery will be two-way and if a discrepancy is seen in the other direction you will seek support from her.
