“The general rule is that where two or more creditors have competing liens against the same property, the creditor whose lien was perfected at the earlier time takes priority over the creditor whose lien was perfected at a later time.”

Thus a mortgage lender has priority liquidation (ownership) over the investor in the tax lean on the property. Very few properties in the USA are fully paid for, thus the lender has control over the property.

There are very few times one will find a fully paid property where the lender is out of the picture, and someone has no money to pay the property tax.

If someone has a fully paid home, they can just go out and get an equity line of credit to pay the property tax or sell the home, and cash out.

I would avoid investing in this real estate TV hype.
