Back to your question, my advice is to not "ask for money" but offer your relative an investment option pointing out the benefits.

Could be a tax issue for your relative since the IRS could consider it a gift and you might have to pick up the interest as income.

No need to spill the beans if it's a secret investment strategy or if your relatives are still in the dark.

Your relatives can get one and in turn loan you the funds and charge interest which you can deduct.

But all interest income on the loan to your relative's IRA will be tax free.

If you haven’t had the conversation with your relative about getting those “unofficial” tenants out, I believe you should do that soon and present your plan how it will be beneficial for both of you and you can begin the process of getting new tenants in. 

What is your relation to the company?

I think that would fly legally.not the smartest for your relatives.. but do check it out.. its when you have multiple bene's on one mortgage trust deed that Securities comes into play..

Once you are licensed, the BRE is expecting that all of your related real estate activity will be under your license and therefore all of the standards of conduct, duties, and I would say disclosures would apply.

You can rent to someone else, but not your relative.
