Im trying to obtain a tax delinquent list for direct mail.

That's especially true if the underlying mortgage is from a large bank (say $250 billion-plus in assets).  

I've bought a few notes on FCIX over the years but generally they are the "bottom of the barrel" assets that are not the best ones

You can invest in various assets, or do several strategies.

Depending on what business structure strategy (asset protection) you are looking for you may want to keep your name off of it. 

Because a vacation home and personal residence are limited to the $10k taxes cap because they are personal assets and therefore deductible on schedule A as an itemized deduction subject to the $10k cap.

Buying a non-performing asset (an asset that generates no income), that I am only going to sleep in that sells for 6, 8 or 10 times the average income in a particular area, is not something I thought was a good "investment" in 2006, nor do I think it is today. 

Are you open to working together and pulling resources to obtain a park(s) in that area? 

I knew that the worst thing that would happen was I would lose 20k and maybe have to liquidate the assets before I finished the rehab.

Home storage has gotten a good bit of negative press and opinion lately, and, of course, the IRC section 4975 text about "providing services" for your IRA assets is something about which you may want to consult with your legal team.
