I'm looking to purchase an airbnb with a 2nd home loan. I have enough funds for a down payment and to furnish it, but funds are a little tight.  I understand an LLC cannot be on the title because that would violate my mortgage, but I am interested in establishing an LLC for liability reasons and to leverage business credit. I see business credit cards such as with US Bank offer 18 months 0 % APR.

I have enough funds in reserve to furnish and cover costs on my own, but I figured it would be valuable to have a 10-15 k cushion while building up business credit for future investments down the line.

Is it feasible/ legal to buy the property with a 2nd home loan, occupy the residence for 14 days, create an LLC management company to manage my property on airbnb, and leverage 15k in 0 % interest through business credit cards. Would there be restrictions on how I use these cards? Would leveraging the business cards in the management company's name be ok to furnish the property?

Would love to know what people think.
