There's not harm, but what's the plan? It should have an origination fee you didn't mention. I wouldn't even bother taking out $5500. An extra account to keep an eye on. You can have lower rate and a higher sum taking cash from a credit card. I got $30k out of cards and invested it.

Any reason not to take out this loan? The interest rate is about 3.5% but Biden may extend the 0% rate again. Even if he doesn’t, as long as I can earn more than 3.5% in the market, or at least match it, what’s the harm?
