What You Need To Know About Co-Signing A Mortgage

Diane Buchanan • June 11, 2025

So you’re thinking about co-signing on a mortgage? Great, let’s talk about what that looks like. Although it’s nice to be in a position to help someone qualify for a mortgage, it’s not a decision that you should make lightly. Co-signing a mortgage could have a significant impact on your financial future. Here are some things to consider.


You’re fully responsible for the mortgage.


Regardless if you’re the principal borrower, co-borrower, or co-signor, if your name is on the mortgage, you are 100% responsible for the debt of the mortgage. Although the term co-signor makes it sound like you’re somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage. When you co-sign for a mortgage, you guarantee that the mortgage payments will be made, even if you aren’t the one making them.


So, if the primary applicant cannot make the payments for whatever reason, you’ll be expected to make them on their behalf. If payments aren’t made, and the mortgage goes into default, the lender will take legal action. This could negatively impact your credit score. So it’s an excellent idea to make sure you trust the primary applicant or have a way to monitor that payments are, in fact, being made so that you don’t end up in a bad financial situation.

 

You’re on the mortgage until they can qualify to remove you.


Once the initial mortgage term has been completed, you won’t be automatically removed from the mortgage. The primary applicant will have to make a new application in their own name and qualify for the mortgage on their own merit. If they don’t qualify, you’ll be kept on the mortgage for the next term.


So before co-signing, it’s a good idea to discuss how long you can expect your name will be on the mortgage. Having a clear and open conversation with the primary applicant and your independent mortgage professional will help outline expectations.


Co-signing a mortgage impacts your debt service ratio.


When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted in your debt service ratios. This means that if you’re looking to qualify for another mortgage in the future, you’ll have to include the payments of the co-signed mortgage in those calculations, even though you aren’t the one making the payments directly.


As this could significantly impact the amount you could borrow in the future, before you co-sign a mortgage, you’ll want to assess your financial future and decide if co-signing makes sense.


Co-signing a mortgage means helping someone get ahead.


While there are certainly things to consider when agreeing to co-sign on a mortgage application, chances are, by being a co-signor, you'll be helping someone you care for get ahead in life. The key to co-signing well is to outline expectations and over-communicate through the mortgage process.


If you have any questions about co-signing on a mortgage or about the mortgage application process in general, please connect anytime. It would be a pleasure to work with you.

Monthly vs. Biweekly Mortgage Payments: Which Is Better?

By Diane Buchanan • October 7, 2026
How Mortgage Payment Frequency Affects What You Pay Over Time You’ve probably heard the saying that there are two certainties in life: death and taxes. When it comes to your mortgage, there’s really just one certainty—you’ll repay what you borrow, plus interest. What is flexible, though, is how often you make your mortgage payments. And that choice can have a meaningful impact on how quickly you pay down your mortgage and how much interest you pay over time. The Six Mortgage Payment Frequencies Most lenders offer the following payment options: Monthly – 12 payments per year Semi-monthly – 24 payments per year Bi-weekly – 26 payments per year Weekly – 52 payments per year Accelerated bi-weekly – 26 payments per year Accelerated weekly – 52 payments per year Standard Payment Frequencies The first four options are designed to align with how you get paid. For example: Paid monthly? Monthly mortgage payments may make sense. Paid every two weeks? Bi-weekly payments can align nicely with your cash flow. With these standard options, regardless of how often you pay, the total amount paid over the year is the same —it’s simply divided into more frequent payments. What Makes “Accelerated” Payments Different Accelerated payments work differently—and this is where the real savings happen. With accelerated bi-weekly or accelerated weekly payments, you’re paying a slightly higher amount each time. That extra money goes directly toward reducing your mortgage principal, which lowers the interest you’ll pay over the life of the mortgage. A Simple Example Let’s assume a $1,000 monthly mortgage payment: Monthly: $1,000 once per month = $12,000 per year Semi-monthly: $500 twice per month = $12,000 per year Bi-weekly: $1,000 × 12 ÷ 26 = $461.54 every two weeks = $12,000 per year Accelerated bi-weekly: $1,000 ÷ 2 = $500 every two weeks = $13,000 per year With accelerated bi-weekly payments, you effectively make two extra payments per year without having to think about it. Those extra payments reduce your principal faster, which lowers interest costs over time. Accelerated weekly payments work the same way—you just make smaller payments more frequently. Why This Matters Long Term While it’s difficult to calculate exact savings due to variables like interest rates, terms, and amortization changes, maintaining an accelerated payment schedule over the life of your mortgage can reduce your amortization by up to three years and save a significant amount of interest. The Bottom Line Accelerated payments are a simple, automatic way to lower your overall cost of borrowing—without needing to make lump-sum payments or drastically change your budget.

Need Funds Between Buying and Selling? Here’s How Deposit Loans & Bridge Financing Help

By Diane Buchanan • September 30, 2026
You’ve outgrown your current home. It no longer fits your life, so moving makes sense. And you’re not interested in juggling two properties. Selling first and buying something new feels like the right move. Ideally, you want possession of the new home before leaving the old one. That overlap makes moving easier, reduces stress, and gives you time to paint, renovate, or settle in before the boxes arrive. But there’s a common challenge. What if the down payment for your next home is tied up in the equity of the one you’re selling? That’s where bridge financing comes in. How bridge financing works Bridge financing temporarily unlocks equity from your current home once it has a firm sale . It bridges the gap between selling your existing property and purchasing your next one, allowing you to use that equity toward your down payment. What about competitive markets? In a hot market, a strong offer often means a larger deposit . If you don’t have that cash sitting in your account, but you do have equity, a deposit loan can help you compete with confidence. The non-negotiable requirement To qualify for bridge financing or a deposit loan, your current home must have a firm, unconditional sale . No firm sale = no bridge or deposit loan. Lenders need certainty to calculate available equity and manage risk. Bottom line A firm sale is the key that unlocks bridge financing and deposit loans. If you’re planning a move and want to understand how these options could work for you, let’s talk. I’m always happy to walk you through your options and help you plan your next step with confidence.
