I think you're probably out of luck on your 16k, and that you will need to get in line behind the mortgage lender.Perhaps your second position lien will survive the judgment and you can seek a garnishment down the road.

Don't put yourself in a bad spot with no money and no real estate experience and expect to pay your bills to survive.

@Clint Harris has more experience with this so he could probably give you more insight into what's allowed and what's not. 

I would like to know does utilities lien survive after tax sale ( wiped out) or new owner needs to pay?

I agree with @Theresa Harris, cash for keys is the way to go.

*In general*, equitable title vests immediately upon passing and probate is about transferring legal title (though in TX, intestate heir has to survive 120-hours). 

@Theresa Harris I never thought about buying a duplex and living in one of the units myself.

@Sean Harris not in mobile parks specifically but shoot me a DM.

The ultimate goals I have in mind are essentially financial freedom (to keep it fairly broad), but I would eventually like to build a legacy through real estate that survives me.I look forward to working with you all throughout this journey, and hope that I can be as much help to you as you have been to me!

As what @Derek Harris mentioned, having a goal is the first thing.
