Second mortgages are loans, which provide an opportunity to borrow money against the value of your home. In many cases, when you buy a property, its value increases over time. A second mortgage enables you to benefit from the equity in your home. If you take out a second mortgage, you can use the money for a range of projects and access capital without selling your home. If you're trying to raise funds or considering borrowing money, this guide will tell you everything you need to know about second mortgages.
What Are the Different Types of Mortgages?
Second mortgages are a loan that you take out against your property. In essence, this type of financial product enables you to capitalize on the equity in your home. If you take out a second mortgage, your home will become collateral. The second mortgage is so-called because if you fall behind with mortgage payments, the first mortgage will be paid off first in a foreclosure. Once the first mortgage is paid off, any remaining funds will go towards the second mortgage. Second mortgages differ from other types of loans, such as auto and student loans, because they can be spent on almost anything.

To discover how a second mortgage works and how it can be beneficial, it's crucial to understand home equity. The amount of equity in your property will affect your borrowing. The more equity you have, the higher the loan value. To calculate the equity tied up in your home, you subtract the amount of money you have paid so far from the total sum you borrowed to buy your house. The equity relates to the portion of your home that you have paid off and own outright.
Most second mortgages fall into one of two categories: a home equity loan or a home equity line of credit, commonly called a HELOC. According to the Consumer Financial Protection Bureau, both are considered second mortgages, or "junior liens," when you already have a first mortgage on the property.
A home equity loan gives you the full amount you're borrowing as a single lump sum, usually with a fixed interest rate. That means your monthly payment stays predictable for the life of the loan, similar to your first mortgage. This structure tends to work well for one-time expenses, like a major renovation or paying off a specific debt, where you know the exact amount you need upfront.
A HELOC, on the other hand, works more like a credit card. You're approved for a maximum credit limit and can draw funds as needed during what's called the draw period, then repay and borrow again up to that limit. HELOCs typically carry a variable interest rate, so your payment can shift as rates change. This flexibility makes a HELOC a common choice for ongoing projects or expenses that unfold over time, such as a multi-phase renovation. Our guide on home renovation loans walks through how homeowners typically choose between the two.
Lenders evaluate a second mortgage application similarly to how they evaluated your original mortgage, with a few extra considerations layered on top. You'll generally need:
Because a second mortgage adds an additional lien on your home, lenders tend to be more conservative about how much they'll approve compared to a first mortgage, particularly if your combined loan-to-value ratio would climb too high.
Since second mortgages aren't tied to a specific purchase the way a first mortgage or auto loan is, homeowners use them for a wide range of goals. Popular uses include funding home improvements or renovations, consolidating higher-interest debt like credit cards into one payment, covering education costs, or financing a large one-time expense such as a medical bill. Some homeowners also use second mortgage funds toward a down payment on an investment or second property, though that approach adds more risk since you're leveraging your primary residence to finance another purchase.
A second mortgage isn't free money, and it's worth going in with a clear picture of the downsides. Because your home secures the loan, the CFPB notes that you could lose your home if you can't keep up with payments. You're also adding to your overall debt burden, which can leave you more vulnerable if your financial situation changes. Second mortgages typically carry higher interest rates than first mortgages, since the second-mortgage lender is paid after the first-mortgage lender in a foreclosure and takes on more risk as a result. If you're considering a second mortgage to consolidate other debt, remember that you're not eliminating that debt, you're moving it onto a loan secured by your house, which raises the stakes if repayment becomes difficult.
A second mortgage isn't the only way to tap your home's equity. A cash-out refinance replaces your existing mortgage entirely with a new, larger loan and gives you the difference in cash, rolling everything into a single monthly payment. A second mortgage, by contrast, sits alongside your existing first mortgage as a separate loan with its own payment. Which option makes more sense usually comes down to your current mortgage rate: if refinancing would mean giving up a much lower rate on your first mortgage, a second mortgage often preserves that original loan while still letting you access equity.
How much can I borrow with a second mortgage? It depends on your home's value, how much you still owe on your first mortgage, and your lender's guidelines, but most lenders cap combined borrowing well below 100% of your home's value to leave a cushion of equity.
Is the interest on a second mortgage tax deductible? It depends on how the funds are used and current tax law, which has changed in recent years. Talk with a tax professional about your specific situation before assuming a deduction applies.
Can I get a second mortgage with an existing HELOC or home equity loan? It's uncommon but not impossible, since lenders will look closely at your combined loan-to-value ratio and may be hesitant to add a third lien on the property.
What happens to my second mortgage if I sell my home? Both your first and second mortgage balances are typically paid off from the sale proceeds at closing, in that order, before you receive any remaining equity.
Second mortgages can be a useful way to put your home's equity to work, but the right structure, whether a home equity loan, a HELOC, or a cash-out refinance, depends on your goals and financial situation. Contact the team at Mares Mortgage to talk through your options.
