If you’re paying for a down payment with a credit card, then you shouldn’t be making the purchase — plain and simple. The only exception is if you’re paying for a down payment on a car and you’re 100% certain you can pay the bill before it accrues interest. And even then, it’s a risky move that the dealer likely won’t jive with.

The Internal Revenue Service (IRS) charges a service fee on all credit card transactions, ranging from 1.85% to 1.98%. While that may not sound like a lot, it’s far cheaper to just pay with a debit card (around $2 per transaction).

Everyone from financial experts to the Securities and Exchange Commission cautions against investing with a credit card. If you lose the money on the market and can’t pay it back, you’ll be stuck with high-interest debt. Plus, most investment firms won’t even let you buy stocks and bonds with a credit card, and those that do might be looking to scam you.

If you want to guarantee financial ruin, then try to put your mortgage payment on a credit card. You’ll be paying for not one but two types of interest. Suffice to say: you’ve got better options. The Consumer Finance Protection Bureau (CFPB) recommends calling your mortgage servicer to work something out and contacting the Department of Housing and Urban Development (HUD). And we have similar advice for renters. Contact assistance programs, and as a last resort, consider taking out a loan.

A cash advance — a short-term loan offered by your credit card company — is almost always a bad idea because the fees are high (around 3% to 5%) and the interest rates are astronomical (as high as 36%). If you can swing it, a personal loan will offer far favorable terms.

Since businesses take a while to be profitable, you shouldn’t rely on high-interest credit card debt to finance your venture. Rather, it’s better to go through more conventional channels and get a small business loan or crowdfund your operation.

For example, some companies treat cryptocurrency purchases like cash advances. And for the same reason you don’t want to invest with a credit card — you shouldn’t gamble with money you don’t have — you should also avoid crypto.
