Years ago, a Canadian friend invested $500k+ with someone in the Alberta market when the oil boom was going on.

Was it caught up in the oil boom that hit Midland and Odessa or is something else at play?  

If the Miami-Dade property is anything other than a single-family dwelling, the tax rate is $.60 plus $.45 surtax per $100 of consideration (or portion thereof).Examples of documents that may transfer an interest in real property include:• Warranty deeds• Quit claim deeds• Contracts for timber, gas, oil, or mineral rights• Easements• Contracts or agreements for deed• Assignments of contract or agreement for deed• Assignments of leasehold interest• Assignments of beneficial interest in a trust• Deeds in lieu of foreclosureConsideration generally includes, but is not limited to:• Money paid or to be paid• Discharge of an obligation• Mortgage or other lien encumbering the property• Exchange of property• Any other consideration which has valueWhen the consideration for real property includes property other than money, the consideration is presumed to be equal to the fair market value of the real property.Tax is due on the total consideration for the transfer regardless of the consideration shown on the face of the deed or other document that transfers the property.

If not wholesaling is the next best option @Christopher Oliver

But unfortunately, "it's the squeaky wheel that gets the oil".

OK, time for my Oil Drilling analogy;You own an oil drill.

Property receives a monthly royalty check for gas and oil rights.

They are a boom and bust oil area that has been in a bust since about 2014 but it will eventually turn again.

Your other option is have a Landlord Meter installed but that could get pretty expensive.Your only other option is to ask to see her electric bill then figure out roughly what the washer and dryer electric would cost should be able to roughly estimate it, then reduce her rent by that number.My property had this issue where the oil furnace was running on one units electric but i was lucky i had a separate elextrical box just had to get a meter installed, then have those items moved over to the new electrical box it only cost me $100 to get done. 

There could be exceptions that the title co doesn't cover (eg. oil/mineral leases from 15 years ago) that could come back to bite you when you go to sell the property again.
