I challenge you and all other buy ad holders to add systems to allow you to be on vacation, even on a cruise. 

If there for sure is no mortgage on the property, then my guess is another lien holder is foreclosing

If the possible judgment is against someone with the same name as the seller, you can contact the judgment holder and verify that the SSN's aren't the same.

I'm using both Visa and MC.

I would also like to add that I am on a work visa and will not be able to rent it out on AirBnb for short term rentals.

Second is in CFPB and or SAFE Act violations, these concerns are for owner occupied residential properties, although even commercial lenders/note holders can be in certain situations successfully sued for wrongful foreclosure, etc.

Generally properties are sold free and clear of interests which are subordinate to the tax lien and where the interest holder has been give proper (legal) notice of the sale. 

Technically, the loan holder can call the entire loan due when you transfer to your name.

Assuming the seller (note holder) is flexible on mobility, what are some known ways to remove these properties from future consideration by a creditor? 

The contract holder will get his note payed and the seller will get the rest of the money.
