LLC formation and maintenance in TX, TN, FL

[Parker Zhou]

Hi - currently have 12 doors and am looking to start moving them into LLCs. I'm looking for some best practices on starting and maintaining LLCs in TX, TN and FL (on a cheap basis…not trying to do everything using a service or having each single family home in each LLC as that would make costs balloon out of control). Mostly looking for advice on whether people filled themselves (or if they have a service they recommend), whether they have a separate bank account for each LLC, what they did for insurance and what they did for the various annual filing requirements. Thanks
