They're revocable trusts (meaning that the trust can be changed) during the lifetime of the property manager(s).

You need opt-in consent before sending a message.

From what I've read, I think sending out an automated mass text message to people who have not provided express written consent is illegal.

Perhaps a revocable trust / SMLLC holding structure would work best.

The moment you apply for a mortgage, that fact is sold by our trusted credit reporting agencies (TransUnion, Equifax, and Experian) to the entire world, so they can start spamming you with junk (one of our lobbying groups, AIME, is trying to make it illegal unless you explicitly give consent to TU, EF, and EP).

EIDL loans are likely to require consent as they will be secured debt.

Never allowed (Which does not mean illegal, always) in the note without expressed written consent from lender.

There doesn't have to be any intent or desire to purchase, and the owner can sell to anyone else at any time without the master lessee's consent.  

@Ellie Narie - (1) Ensure this is in future leases and (2) try to get their written consent to amend the current lease.

I had a similar situation:  did a sub-to by having the seller establish an intervivos revocable trust, with my entity as trustee and the sellers as beneficiary.
