I can lend to anybody from my SDIRA as long as they are not disqualified person (not you, your spouse, your children, or parents).

Bush just missed a similar fate after falling off a Segway at his parents’ summer home in Kennebunkport, Maine.

I want to move near my parents in NJ (Monmouth County area).

His parents sued my parents. 

Essentially it allows you to have a parent or holding LLC with a multitude of “series” beneath it that are each separate and protected, limiting liability without having to continually open individual LLCs.

And my parents live in Redlands, so I'm through there quite a bit getting out there.

I'm trying to figure how I should be going about offering on deals, and any insight would be helpful.I currently have about 100k in investible cash, my home is how worth about 160k, my 2016 and 2017 tax returns can support a modest 250k loan, my 2019 return will be significantly higher but I haven't filed yet at the advice of my CPA, I have ~150k in retirement accounts that I could access, and my parents would like to partner and are willing to contribute 100k. 

I'm withholding judgement on this one until later.

I had my parents co-sign and then recently re-financed to get them off the loan (using the now established rental income).

Might be easier if you parents are willing and able to co-sign.
