Is there any situation to take credit to invest in ?

My fiance wants to take advantage of a low priced right now but we don’t have the cash to pay for it unless we use LOC or credit card.

The LOC is roughly around 9% and is already up to around 10K.

I’m hesitant since we have a wedding to pay for.

Would it benefit us to purchase now or wait until we have tangible to invest?
