If you have enough money in your retirement account it is a win win... you are using your own capital and paying yourself interest.Disclaimer...I don't promote 401k accounts to be your primary investment vehicle.  

In the past, I rolled it into IRA's - my last custodian and favorite custodian for market-based investments was TD Ameritrade.Now that I have an REI business, I've taken advantage of the ability to open a Solo 401K account w/ checkbook control, which blows away pretty much every other retirement vehicle IMO. 

(How one takes care of their vehicle is often indicative of how well they will take care of their home.

I still think it's a good alternative investment vehicle, but as something that diversifies against other types of investments. 

Things that will help a lot are any neighbors that saw them loading the property into their vehicle or witnesses to them taking a hammer to your walls.

There may be other vehicles available to you for asset protection as opposed to traditional LLCs.

What vehicle do you plan to use for the affordable housing, if any for subsidy?

And self-directed IRA is a great vehicle to do so giving the opportunity to invest in alternative assets, get out of the stock market and achieve true diversification which is not possible with conventional IRA. 

It's a lot like finding the right car or truck that meets your needs, understanding the different options for the vehicle and selecting the options needed to build the best vehicle for you.

In Colorado the tow company can tow it, then after (I think) 30 days, put a lien on the vehicle, and then start the title process.
