RE Agent is also Principal in Transaction - Use of Forms Texas

[Miles Stanley]

I'm currently in the middle of getting my Real Estate Agent license and hope to have it done by end of year.

i was studying my Law of Contracts material and i came across the rule (537.11) that states that agents must use TREC promulgated forms in a transaction unless the license holder (me) is acting SOLELY as principal or the principal (client) requires use of another contract and/or one prepared by an attorney.  

Question is, what if i want to purchase a property for my own portfolio while acting as an agent (i.e. i would be principal AND agent representing myself).  I know i have to disclose this, but what about use of promulgated forms?  Could i still have an attorney-drafted contract if a situation required it or would i still be bound to using a TREC form since i am also acting as an agent?

If this is answered elsewhere or if anyone knows of a blog post or video that addresses this, please share.

I might be overthinking or over-complicating this,.

Thank you,
