You can rent your primary home for up to 14 days a year tax free. 

They may want an S-Corp for tax purposes.

I am thinking of doing a cash out refi on the rental to fully payoff my primary residence if it would be advantageous from a tax perspective (given the new tax law's higher standard deduction for schedule A, I may not qualify for itemized for W2 income).  

We would be living in the house for at least 2 years because my understanding is that is when you are free of capital gains taxes if you decide to sell.

Downside to this is there are some tax implications due to tax basis3.

They can at least give you the address that they mail the tax bill to.

Monthly income, expenses, insurance, taxes, etc)?? 

The state of Alabama purchases the delinquent taxes from the county once they dont get sold in a tax sale so that the municipality can pay their employees.

Just be sure that the property will cash flow enough to cover all your normal expenses (debt service on the 30 yr loan, CapEx, repairs, vacancy, taxes & ins, etc) PLUS enough extra to pay off the LOC in a reasonable anoint of time.

I feel that I paid way too much in taxes last year.
