3) If an outstanding balance is remaining on the senior lien after a "leftover payment" from the junior lien, what are the steps to contacting and paying off the senior lien once I purchase the property at auction?  

The city attorney's office seized the property from the landlord due to the 16 outstanding orders of abatement on the property. 3 occupied, 1 vacant and 4 "guest rooms" in the basement that was overrun by druggies, drug dealers, bike thieves, etc.The 3 occupied units upstairs were vacated through several different strategies and one case of dumb luck on our part.Only one person in the basement claimed tenancy with a lease.

@Caroline Barnett sometimes the reason people don't switch utilities is do to having an unpaid outstanding balance with the utility company.

In Texas the owner must file their petition before the second anniversary of the date of the sale of the property and they are divvied according to all that is owed ie: all outstanding legal debts in the order they occurred. 

They have outstanding PM in house.  

I think the areas you are considering are outstanding, and I hope to snag some properties there myself.  

That's what the company researching the title does, so before closing you know about any outstanding liens.

After I made the offer the seller's agent told us the property is part of an estate and has an $81,000 outstanding mortgage.

You basically just answered your own question, when you move it to the LLC, you are selling it to that LLC. you would have a closing and everything because the Title would have to be changed, and there is a possibility that the " due on sale" clause will take effect and what ever you have outstanding on your loan, the bank could call due.

Has anyone bought a condo or town home in New Jersey subject to an outstanding HOA Lien?
