I'm looking to get their "package" which includes a Holding company, LLC Subsidiary​, Corporate Financial Program and an Estate Plan.

why are you wanting the LLC? 

For TX investments, look into forming a Series LLC.

So, if you create an LLC in another state, you will likely need to register it as a foreign LLC in California.

If changing your LLC name isn’t feasible, consider using a DBA for credit applications.

Tools like Baselane simplifies bookkeeping and tax preparation by categorizing transactions and storing records.Keep personal and business accounts separate to maintain LLC liability protection.Please don't use the same LLC for flips and rentals.

Quote from @Faysal Alam: What banks or credit union can I use to refinance a car under my LLC name , my car is a 2023 Tesla model y performance , I owe $42,500 on the car , I’m looking to refinance the car under my business , my business was established 03/2023 .

How do hard money lenders that do not put them selves out to the public and lend only to 3 individuals I know that have LLC's.

It must be signed by either the agent for the LLC or the president.

If the answer to both added questions would be "yes", then you have a potential goldmine here.Combining the seller's concerns, and the reality of a big down payment being a negative to the seller (see Q: 1), you should be able to set the terms, with a lower DP, and controlled interest rate, to have this property CF and,...be able to sell the package to another REI down the road,...as long as you buy this using an LLC (a new one).
