Key takeaways
- A second mortgage is a home-secured loan taken out while the original, or first, mortgage is still being repaid. Like the first, the second mortgage uses your property as collateral.
- A home equity loan and a home equity line of credit (HELOC) are two common types of second mortgages.
- Second mortgages typically have higher interest rates than primary mortgages, but are often cheaper than credit cards or personal loans.
- To qualify for a second mortgage, you must have built up a certain amount of equity (outright ownership stake) in your home, maintain a minimum amount of equity in the home, and have a strong credit score.
With prices climbing every month for the past 21 months, home values are at near-record highs. That’s good news if you already own a home: The average mortgage-holding homeowner had $303,000 in equity at the end of 2024, according to property information and data analyst Cotality.
If they need cash, homeowners can tap their equity for ready money by taking out a second mortgage. It’s similar to the primary mortgage – the one that purchased the home – but with some important differences.
Before you can take equity from your home, you need to understand how second mortgages work, and whether one makes sense for you.
What is a second mortgage?
Most people think of mortgages as loans to buy a home. But once you become an owner, you can continue to borrow. A second mortgage is exactly what it sounds like: another loan that uses your home as collateral.
Your original mortgage is known as a first or primary mortgage — not only because you took it out first, but because the mortgage lender has first dibs on the home should you default on payments. Any additional loan against the property is called a subordinate mortgage or a subordinate lien. As the name implies, this second mortgage is junior to the first one in terms of reimbursing creditors or lenders — they’re second-in-line to get paid if you get foreclosed on or become bankrupt.
When you take out a second mortgage, you borrow against the equity you’ve built up in your home. Equity refers to the amount of the home you own outright, as opposed to the amount you still owe; in other words, the difference between the value of your home and the remaining balance on your first mortgage.
How does a second mortgage work?
A second mortgage works a lot like a first mortgage — in the opening stages, anyway.
To obtain a second mortgage, you typically need to do the same things you did to qualify for a primary mortgage. The process includes submitting an application to a lender and providing documentation regarding your income, debts and assets. You might also need to get an appraisal to confirm the current value of your home and to pay closing costs (though some lenders cover them for you). Finally, you’ll need to sign loads of paperwork stipulating what the lender can do if you don’t live up to your repayment terms.
Qualifications for second mortgages vary, but many lenders prefer that you have at least 15 percent to 20 percent equity in your home. You can typically borrow up to 85 percent of your home’s value minus your current mortgage debts. If you have a home worth $300,000 and $200,000 remaining on your first mortgage, for instance, you might be able to borrow as much as $55,000 through a second mortgage: ($300,000 x 0.85) – $200,000.
Requirements for applying for a second mortgage
To apply for a second mortgage, you must meet the following requirements:
- Own at least 15% to 20% of the home outright
- Have a remaining balance on your current mortgage that’s less than 80% to 85% of the home’s value
- Have a credit score of 620 (at the very least; a higher score is strongly recommended to qualify for the lowest rates)
Can you get a second mortgage if you have bad credit?
Qualifying for a second mortgage with bad credit is challenging, especially since lenders set a high bar for these inherently riskier loans to begin with: Many expect your FICO score to be at a minimum “good” (670) or high “fair” (640-669).
Still, loan approval is possible, especially if you have a sizable equity stake. To improve your chances, consider trying your primary mortgage lender first (assuming it offers second mortgages). Another option is to secure a co-signer with a strong credit profile, which can make you a more attractive candidate.
If you do get approved, expect higher interest rates and stricter terms — the price you pay for your less-than-brilliant credit.
What are the pros and cons of getting a second mortgage?
Second mortgages can be helpful in a variety of situations, but they do have drawbacks to consider.
Pros
- Access your equity. Their home is one of the most valuable assets most Americans have. A second mortgage lets you turn that (usually) illiquid asset into usable cash. You’re funding yourself, so to speak.
- Low interest rates. While higher than a purchase mortgage, a second mortgage boasts some of the lowest interest rates available — lower than personal loans and credit cards.
- Multiple options for withdrawing funds. Depending on the exact vehicle, you can opt to receive money in a lump sum (the home equity loan) or receive it in stages (the home equity line of credit).
- Tax advantages. If used for home-related improvements or repairs, second mortgage interest can be tax-deductible.
Cons
- Lengthy, expensive application. Applying for a second mortgage loan is a lot like applying for the first. It may take a while to get approval, and you’ll incur closing costs, too.
- Limits on loan size. The amount you can borrow is circumscribed by how much of your home you own outright and your mortgage balance.
- A new monthly payment. Getting a second mortgage means adding another monthly obligation to your budget.
- Puts your home at risk. Borrowing against your home means you’ll be putting it on the line; if you can’t make payments, you could lose it.
Types of second mortgages
Borrowers who wish to take out second mortgages can choose between two basic types: home equity loans or home equity lines of credit.
Home equity loan
A home equity loan works pretty much like a first mortgage. You receive all of the money upfront and pay it back over time with interest in fixed monthly payments. These loans are ideal for situations in which you need a sum of cash at one time, such as paying off a big debt or paying for a single, one-time expense, like a kitchen renovation or a new swimming pool.
Before applying, do some research into current home equity loan rates. Typically, rates are a few percentage points higher than mortgage rates. Bankrate’s home equity loan calculator can help you see if such a loan makes sense for you, and how much money you could tap.
Home equity line of credit (HELOC)
A HELOC is a line of credit, similar to a big credit card. Once it’s established, you can draw on it over several years, as often as you want and in the amounts that you want. You’re charged interest only on the amount that you actually withdraw. You can repay the sums you borrow, then borrow again.
HELOCs can be a great option if you’re not sure exactly how much money you’ll need or if you’ll need it over a long period of time. Examples may include paying college tuition or embarking on a remodeling project — like a home addition — that’ll take a good many months and whose contractors will be reimbursed in stages.
HELOC interest rates typically run a few percentage points higher than mortgage rates and slightly above home equity loan rates. However, unlike the other two, they are usually variable. That means they can fluctuate, rising and falling with interest rates in general.Bankrate’s HELOC payoff calculator can help you see if this option makes sense for you..
Home equity loan vs. HELOC
A home equity loan is probably a simpler, easier proposition if you need a five-figure lump sum for defined or finite expenses. On the other hand, a HELOC might be a better option when you have ongoing financial needs, such as recurring tuition payments, or as an emergency fund.
What’s the difference between a second mortgage and a refinance?
Refinancing your mortgage is quite different from getting a second mortgage.
When you refinance, you’re replacing your original mortgage with an entirely new loan with a new rate and new term. When you get a second mortgage, you’ll keep that first mortgage (a good move if you have an attractive rate on that outstanding balance) while adding another loan that gives you two separate payments each month.
Another key difference is timing: Refinancing generally takes as long as getting your first mortgage did – think 30 to 60 days to close, depending on the lender. If you opt for second mortgage, especially a HELOC, you may be able to access the funds significantly quicker.
When a cash-out refinance makes sense
There’s a particular type of refinancing that allows you to tap your home equity, too: a cash-out refinance.
With a cash-out refi, you take out a new mortgage with a bigger balance than your current mortgage, pocketing the difference in cash. The extra amount is based on the value of your home equity. Of course, this move leaves you with a bigger loan to pay off, and larger payments (usually fixed) to make each month.
Refinancing can be a good choice if, in addition to obtaining cash, you want to adjust the repayment term of your existing mortgage or can secure a lower interest rate on the new loan. Plus, you get the perk of just one monthly payment, instead of two separate ones (as you’d have with a second mortgage).
When a home equity loan or HELOC makes sense
A home equity loan or HELOC would be the better option if you want to hang onto your current mortgage’s low-low rate, or unsure of how long or how much money you’ll need. But they work best if you own a good chunk of your home free and clear, since your outstanding mortgage balance will impact how big an additional loan you can get. If you still owe a lot, the refi might be the better scenario after all.
Final word on second mortgages
A second mortgage can sound daunting – it’s another lien on the roof over your head. However, it can be a valuable weapon in your financial toolbox. If you’ve paid off a substantial amount of the principal on your primary mortgage and you have excellent credit, a second mortgage can help you access capital at a competitive rate to pursue other life goals such as improving your home, funding a business or paying for a child’s college tuition.
While it’s appealing, taking out a second mortgage should be treated with the same level of care and consideration you used for your first mortgage. Can you really afford the payments? Are you 100-percent confident with your repayment plan? Remember, you’ll be taking on more debt while putting your home on the line, which means that any missteps can have dire consequences.
