It’s a risky move to use credit cards to invest if it means you’ll have to pay additional fees for a purchase, or if you plan on carrying a balance that could accrue interest. But it might be worth it if any potential rewards outweigh the fees, and if you have a 0% APR credit card to avoid interest charges. It could also make sense to use credit cards for real estate investing. There are plenty of extra expenses involved with real estate investing, such as paying for repairs or buying renovation supplies. You can put many or all of those expenses onto credit cards. This could increase your cash flow and offer valuable rewards on purchases you were already planning on making. Just make sure you pay off the balances in time to avoid paying interest.
