The specifics usually depend on agreements with the tribal government.

If I was to purchase the property from her without realtors involved on either side how would I do so?  

Depends on the operating agreement and docs you signed.

Ok I am representing the buyer not the seller. and I will have a buyer agreement in place.

All the best, Steven  If you're going to do a partnership or even a joint venture agreement I would highly suggest using a competent lawyer to draft your business agreement.

@Victor YangWhy are you not reaching out to a NC real estate attorney to draw up a document that spells out the agreement that you are looking to do with the tenant?

They have land under contract, $2B in agreements signed so far, so that’s it really.

I came across one of these loan agreements online somewhere a few months ago, can't recall where I found it but it was clear in reading the loan agreement there was no language referencing the loan actually encumbering real property, it was just an unsecured loan.  

After voicing that I will be hiring an attorney and filing a compliant with the Utah Division of Consumer Protection all my ad spend was cut off without warning to make it look like I violating the agreement and I was also locked out of some areas CRM system.

I went through similar experience when I purchase rentals from a turnkey provider in Indianapolis.
