Series LLC vs Parent company LLC for properties in Texas

[Michelle Manning]

I recently began my journey to Fast FIRE through multifamily rental properties. My husband and I are both MDs, so asset protection is always a key motivation for us. I set up an LLC prior to purchasing my first property. I then added 2 duplexes. I am about to close on another property and had initially planned to put it in a new LLC owned by the original LLC, but am now thinking a series LLC might be better. However, I have no time to create the series LLC prior to closing on the next property. So my question is two-fold - 1. Which structure do many of you prefer in Texas - series LLC or parent LLC with multiple LLCs under it? 2. If I buy this new property with my existing LLC, then want to move it into a new series or "child LLC", what is the procedure and what are the tax/legal ramifications? THanks so much for any info/advice - I am learning so much from reading posts on this site!!
