However, after 1 year they are been investigated by SEC and we have not received any payment since pst 1 year.  

You must investigate how that will be handled in California.

@Robert Gambill have you investigated whether or not the existing loan is assumable?  

Any particular sites you investigate? 

I ask because I keep a comparison chart of real estate crowdfunding investments, and I’m constantly on the lookout for new and innovative platforms that I haven’t investigated yet.

There are only a few asset classes and types of investments you can’t invest in in a self-directed retirement account (401k or IRA):1) Life insurance2) Collectibles3) investments in entities that are S-corpsThere are also rules surrounding prohibited transactions and disqualified persons which it appears you investigated.

Just beginning to investigate STRs opportunities in ski/winter vacation detonations.When looking into places like Glenwood Springs/Carbondale, Co and Lake Tahoe, I am seeing a lot of push-back and regulations that keep STRs out of the market. 

We are just beginning the investigation on the area but would like to make a purchase mid to late 2021 if the we can find the right property.

I would also investigate to see if it's breaking because your tenant is abusing/neglecting it or if it's something outside of his control.The same is true for all these repairs.

@William Simmons,I am currently investigating Self-Directed IRA Custodians since mine is getting out of the business :-(  I looked at UDirect, and it appears that they are not a custodian, but rather connect you with a custodian.
