Can one use a tax lien to transfer ownership? Inherited FL home.

[David Shulski]

My Parents have a 1/6 ownership interest in an inherited Florida residence.  They manage all the affairs of the house (rents, expenses etc.), and the other 5 owners have no interest in taking care of the property.  It would not be easy to coordinate a sale for multiple reasons.  They spoke to an attorney in Florida who said, in most of these cases like this, the house is given up to a tax lien.  Would it be unethical or even illegal for my Parents to stop paying the taxes, knowing that I was going to buy the tax lien?  Again, the other owners could care less about the property, and my Parents really don't want to be landlords, so it's most likely going to be lost to a tax lien either way.  One more thing, I have never bought a tax lien so I'm not even sure if I could even pull this off if I wanted to.  Any insight would be greatly appreciated.
