@Sarah T.
Not being a lawyer or an accountant, please take this opinion as just that.
You may be confused by attempting to use the same entity for both you as the RE Agent and you as the RE Investor. While not strictly necessary, if I were in this scenario I would have two separate entities. The Texas SOS site says you may use an LLC as a licensed Agent. This should not need a Broker of Record as this entity would never be the Broker on a deal and would just be the payee of the actual broker when you earn commissions.
Your RE Investor entity will be the purchaser / seller on specific real estate transactions and thus as it has an ownership interest is not involved in the transaction as a representative of another person or entity and does not need a real estate license or Broker of Record. (Some may interpret corporation law to mean that you as an individual could not perform the search for and marketing of real estate for this Investor entity unless you are a licensed agent or a W2 employee. I believe this less likely in an LLC than with a standard corporation.)
Net when you are working as an agent, even for your own investment, your income, expenses and liability belong to your agent LLC. and when you are owning, rehabbing, renting or exiting the investment properties, these belong in the investment LLC.
A long winded way of saying you need to get professional help to do this correctly.
