Closed on a deal need help with next steps

[Annu Zer]

Working with a partner(brother), we were able to close on a property. He used his assets, to get a commercial loan, and the deed for the property is under the name of the LLC he setup. Since it would have delayed/complicated things, only he is on the LLC which has the deed. Propert is in LLC and so is he.

Now we are working on creating an LLC that I will own, and will make a contract with his LLC, to have 30% ownership rights, starting with 30% of income, and when sold, 30% of the share of the property. I am in Oregon

It is first time for both of us, so new, so our plan is below:

1) I create an LLC in Texas, and we make a contract between LLC (mine and his) about the 30% rights/ownership

2) While he pays mortgage(it is under his name and all), I pay him monthly payments based on my share, we include this in contract as well.

Is this something normal or we way out of norm and this will not be legally possible? We are both open to change, but since deed is already under his LLC, and mortgage under his name, it is already done, so we need to move forward from there. It was the quickest way to close at the time, as it made the loan process simple and straightforward.
