What is a Second Mortgage?

Cynthia Dreger • February 21, 2024

If you're not all that familiar with the ins and outs of mortgage financing, the term "second mortgage" might cause a bit of confusion. Many people incorrectly assume that a second mortgage is arranged when your first term is up for renewal or when you sell your first home. They think that the next mortgage you get is your "second mortgage." This is not the case.


A second mortgage is an additional mortgage on a single property, not the second mortgage you get in your lifetime.


When you borrow money to buy a house, your lawyer or notary will register your mortgage on the property title in what is called first position. This means that your mortgage lender has the first claim against the sale proceeds if you sell your property. If you happen to default on your mortgage, this is the security the lender has in repossessing your property. A second mortgage falls in behind the first mortgage on your property title.


When you sell your property, the lawyers will use the sale proceeds to pay off your mortgages in sequence, the first position mortgage is paid out first, and the second mortgage is paid out second. After both mortgages are paid off completely, you get the remaining equity.


When you secure a second mortgage, you continue making payments on your first mortgage as per your mortgage agreement. You must also then fulfill the terms of the second mortgage. 


So why would you want a second mortgage? Well, a second mortgage comes in handy when you're looking to access some of your home equity, but you either have excellent terms on your first mortgage that you don't want to break, or you’d incur a huge penalty to break your first mortgage. Instead of refinancing the first mortgage, a second mortgage can be a better option. 


A second mortgage is often used as a short-term debt consolidation tool to help provide you with better cash flow. If you’ve accumulated a considerable amount of high-interest unsecured debt, and you have equity in your home, you can secure a second mortgage to lower your overall cost of borrowing.

If you’ve been thinking about selling your existing property, for whatever reason, it would be in your best interest to connect with an independent mortgage professional before calling your real estate agent or listing it yourself. And while talking with your mortgage professional might not sound like the most logical place to start, here are a few scenarios that explain why it makes the most sense. If you’re buying a new property If you’re selling your property, chances are, you’ll have to move somewhere! So, if you plan on buying a new property using the equity from the sale of your existing property, chances are you’ll need a new mortgage. Don’t assume that just because you’ve secured mortgage financing before, that you’ll qualify again. Mortgage rules are constantly changing; make sure you have a pre-approval in place before you list your property. Also, by connecting with a mortgage professional first, you can look into your existing mortgage terms. You might be able to port your mortgage instead of getting a new one, which could save you some money. If you’re not buying a new property Even if you aren’t buying a new property and want to sell your existing property, it’s still a good idea to connect with a mortgage professional first, as we can look at the cost of breaking your mortgage together. Unless you have an open mortgage, or a line of credit, there will be a penalty to break your mortgage. The goal is to work on a plan to minimize your penalty. Because of how mortgage penalties work, sometimes it’s just a matter of waiting a few months to save thousands. You'll never know unless you take a look at the details. Marital breakdown The simple truth is that marriages break down. When that happens, often, people want closure, and unfortunately, they make decisions without really thinking them through or seeing the full picture. So, instead of simply selling the family home because that feels like the only option, please know that special programs exist that allow one party to buy out the former spouse. The key here is to have a legal separation agreement is in place. If you’d like to discuss the sale of your property and your plans for the future, connect anytime. It would be a pleasure to work with you!

Can You Afford That Mortgage? Let’s Talk About Debt Service Ratios One of the biggest factors lenders look at when deciding whether you qualify for a mortgage is something called your debt service ratios. It’s a financial check-up to make sure you can handle the payments—not just for your new home, but for everything else you owe as well. If you’d rather skip the math and have someone walk through this with you, that’s what I’m here for. But if you like to understand how things work behind the scenes, keep reading. We’re going to break down what these ratios are, how to calculate them, and why they matter when it comes to getting approved. What Are Debt Service Ratios? Debt service ratios measure your ability to manage your financial obligations based on your income. There are two key ratios lenders care about: Gross Debt Service (GDS) This looks at the percentage of your income that would go toward housing expenses only. 2. Total Debt Service (TDS) This includes your housing costs plus all other debt payments—car loans, credit cards, student loans, support payments, etc. How to Calculate GDS and TDS Let’s break down the formulas. GDS Formula: (P + I + T + H + Condo Fees*) ÷ Gross Monthly Income Where: P = Principal I = Interest T = Property Taxes H = Heat Condo fees are usually calculated at 50% of the total amount TDS Formula: (GDS + Monthly Debt Payments) ÷ Gross Monthly Income These ratios tell lenders if your budget is already stretched too thin—or if you’ve got room to safely take on a mortgage. How High Is Too High? Most lenders follow maximum thresholds, especially for insured (high-ratio) mortgages. As of now, those limits are typically: GDS: Max 39% TDS: Max 44% Go above those numbers and your application could be declined, regardless of how confident you feel about your ability to manage the payments. Real-World Example Let’s say you’re earning $90,000 a year, or $7,500 a month. You find a home you love, and the monthly housing costs (mortgage payment, property tax, heat) total $1,700/month. GDS = $1,700 ÷ $7,500 = 22.7% You’re well under the 39% cap—so far, so good. Now factor in your other monthly obligations: Car loan: $300 Child support: $500 Credit card/line of credit payments: $700 Total other debt = $1,500/month Now add that to the $1,700 in housing costs: TDS = $3,200 ÷ $7,500 = 42.7% Uh oh. Even though your GDS looks great, your TDS is just over the 42% limit. That could put your mortgage approval at risk—even if you’re paying similar or higher rent now. What Can You Do? In cases like this, small adjustments can make a big difference: Consolidate or restructure your debts to lower monthly payments Reallocate part of your down payment to reduce high-interest debt Add a co-applicant to increase qualifying income Wait and build savings or credit strength before applying This is where working with an experienced mortgage professional pays off. We can look at your entire financial picture and help you make strategic moves to qualify confidently. Don’t Leave It to Chance Everyone’s situation is different, and debt service ratios aren’t something you want to guess at. The earlier you start the conversation, the more time you’ll have to improve your numbers and boost your chances of approval. If you're wondering how much home you can afford—or want help analyzing your own GDS and TDS—let’s connect. I’d be happy to walk through your numbers and help you build a solid mortgage strategy.
