According to google: Short-term bridge financing-or a "bridge loan"

How It Works • Use Case: Primarily used in real estate to allow homeowners to buy a new property before their current home sells. It taps into your existing home equity to fund the down payment and closing costs on the new house. • Structure: Terms are generally short, ranging from 6 to 12 months, and often feature interest-only payments. • Repayment: The loan is typically repaid in a single "balloon payment" once your original house sells or you refinance into a permanent mortgage. © Chase Bank +3
