Quote from @Marc Shin: I saw a video by Miles Golden and he said you change transfer your primary mortgage to a HELOC, and then you can pay all your bills out of the HELOC and pay off your mortgage in 3-12 years. 

Note: We do 50+ investment property loans a month and the most important thing I tell BUYERS of properties being sold as or soon to be STR is make sure you are paying the market price per square foot and do NOT buy based on income approach/CAP rate.

We wanted additional units to pay mortgage and have cash flow.

My mark up is always lower than the direct lender because I don't spend money advertising during the Super Bowl or buying a private jet for my CEO, and we don't have layers of management we need to pay.

We have not disabled ours or converted to gas, but Tenant must sign a Fireplace Addendum stating if they use it, we require a higher renter's liability policy with us as additional insured, rules on wood, storage, use, safety, they pay for yearly professional cleaning each year they are there, etc.  

Every dime went into a SFH, live-in flip, and my brother was paying $400 to live with me.

Can I pay property taxes in January that are due now, then deduct them as well as next years that I will (plan to, anyway) pay in December of next year?

But, that $50,000 investment will pay back $75,000 (beats wall street).

So you are already paying tax on the income.LLC taxed as an S Corp would be different, but I doubt that is your case.

I believe if your mother-in-law runs out of money that Medicaid will step in and pay for the nursing care.
