0% Interest Business Credit Card (New One Opened Annually

[David G Vreeland]

Basic Question: 
Is there any downside to opening a new business credit card every year under a new LLC as essentially a 0% loan until I have enough for all the properties I plan on eventually transferring to them?

Context:
Last year I took out a 2% cash back business credit card with a 15 month 0% APR. I've used it for all my various expenses including personal and will be paying off the $9,000 balance shortly before the 15 month promo is up. This credit card does not show up on my personal account and once its paid off it will help build up my business credit over time. I'm pretty aggressive with my investing between stocks and real estate and have enough constant w2 and passive income that even if everything goes sideways I won't have a problem paying off the balloon payment before it starts accruing interest.

Couple Things to Note:

The credit balances on the business credit card don't appear negatively affect my personal credit.

The only ding to my personal credit is the initial credit pull assuming my payments are current.

The LLCs I would be opening the card with would not have property transferred into their names until after the intro APR period is up. At which point the cards would be used exclusively for business transactions related to the property.

I do primarily owner occupied investments so personal credit is very important but will eventually use business credit for property purchases.

Its smart, but you have to factor in the costs of the LLC and opening / closing them / paying yearly fees. I generally leverage 0% APR myself for personal purchases that otherwise would have been cash out of the window and make a minimum payment, then when I know its coming up pay it off and onto the next.
