Second Mortgage

What is a Second Mortgage and How Does It Work?

A second mortgage is a subordinate loan taken out against your home’s equity while your original mortgage remains active. It allows you to access cash by borrowing against your home’s value beyond the first mortgage balance, typically with higher interest rates due to increased lender risk.

A second mortgage is an additional loan secured by your home that ranks behind the primary mortgage in repayment priority. If you default, the first mortgage lender is paid from any foreclosure sale proceeds before the second mortgage lender. This ranking means second mortgages usually have higher interest rates because they are riskier.

Homeowners accumulate “home equity” as they pay down their first mortgage or as property values rise. A second mortgage lets you borrow against this equity, providing funds upfront or via a credit line depending on the loan type.

There are two primary types of second mortgages:

  • Home Equity Loan (HEL): This is a fixed amount borrowed all at once with a set repayment schedule and usually a fixed interest rate. It’s ideal for one-time expenses like home renovations or consolidating debt.

  • Home Equity Line of Credit (HELOC): This works like a revolving credit line, allowing flexible borrowing up to a limit during a draw period (often 5-10 years), followed by a repayment period where you pay principal and interest. HELOCs typically have variable interest rates.

Before applying for a second mortgage, ensure you have sufficient equity (lenders generally require keeping 15%-20% equity after the loan) and a good credit score for favorable terms. Consider the impact on your monthly budget, closing costs, and the risks, including foreclosure if you cannot repay.

A second mortgage can finance home improvements, debt consolidation, education costs, or emergencies, but it also increases your total debt secured by your home. Always compare alternatives like personal loans, cash-out refinancing, or credit cards to find the best option for your financial situation.

A short recast lets you lower monthly mortgage payments by making a lump-sum principal payment and having your servicer re-amortize the loan—often cheaper and faster than refinancing when you want lower payments without changing the interest rate or loan term.
