I just discovered that if I live in California and I have an LLC (in or out of state) I will be required to pay Franchise Tax in California (annually 800$) for each LLC.My first plan was to create for each property its own LLC.This discover is changing my plans (and my numbers of course 🙄 )A few options that came to my mind to try to avoid this route:1.

Extension is necessary unless you want to roll a dice with franchise offices like H&R Block.

Also, CA charges $800/yr in minimum franchise fees for out of state LLC's as long as you live in CA and file taxes there. 

If they're not in your area...it  could be a good franchising opportunity for you. :-)

On the flip side of that, I do like is the idea  only having to pay that one annual $300 franchise tax fee to the state. 

On the other hand, keep in mind that there are costs associated with maintaining an LLC (such as the $800 annual franchise tax in California).2.

@Erjia Mao I have found my deals through another investor that I work with that has a HomeVestor franchise and through Wholesalers.

There are ways to get around the CA franchise fee for out of state properties by using trusts that are exempt from the fee.I remember that one of them was the use of Delaware Statutory Trust to hold the foreign LLC.

NNN of restaurant franchise like KFC etc.

Series LLCs have potential issues with integration and with perceived problems with franchise taxes.
