I refinanced it during the seventh month at a value of $260,000, and got most of my initial down payment back out!

Also once in the LLC, it will also limit your availability of refinancing (more expensive commercial lender).

I thought it had to be my primary residence until paid off or refinanced.

Since it sounds like most of the debt on the properties are not even on-title (business lines of credit), you'll have access to the most funds as a lump-sum this way through one transaction as opposed to individually refinancing them. 

I talked to my lender today, and they don't require a seasoning period before refinancing.

But if you do so then that LLC is going to have seasoning issues and I'm uncertain how you would refi a TIC interest without refinancing the entire thing. 

I went for a refinance over 2 multi family properties and we ended up refinancing one and the other was left free and clear.

Refinancing in a soft market can leave you in a very bad spot if you are not careful.

Refinancing a loan that was initially used for business purposes (purchase/rehab) seems to fit the bill, including private unsecured loans and credit cards.

We just received loan document for refinancing our commercial loan that we do not want to sign, 10 years loan.
