As Simple as Porting Your Mortgage!

Christine Buemann • October 21, 2020
As simple as porting your mortgage! Said by no one ever. The truth is, there is nothing simple about porting your mortgage.

"Porting your mortgage" involves transferring the remainder of your existing mortgage term, outstanding principal balance, and interest rate to a new property. This is of course, if you are selling your current home and buying a new one.

Despite what some of the big banks would lead you to believe, porting your mortgage is not an easy process. It's not a magic process that guarantees you will qualify for the purchase of a new property using the mortgage you had on a previous property. In addition to completely re-qualifying for the mortgage, and having to qualify the property you are purchasing, there are a lot of moving parts that come into play. It seems that executing a port flawlessly is like having the stars align perfectly, chances are, it's not going to happen. Here are a few reasons why:

  • You may not qualify for the mortgage.

Let's say you are moving to a new city to take a new job, if you are relying on porting your mortgage in order to buy a new house, you will have to substantiate your new income. If you are on probation, or have changed professions, there is a chance the lender will decline your application. Porting a mortgage is a lot like qualifying for a new mortgage, just with more conditions.

  • The property you are buying has to be approved.

So let's say that your income is in good shape, and that you qualify for the mortgage, the property you want to purchase has to be approved as well. Just because they accepted your last property as collateral for the mortgage, doesn't mean the lender will accept the new property. An appraisal will be required, and the condition of the property you are buying will be scrutinized.

  • Value's are rarely the same.

How often do you buy a property that is exactly the same value as the one you just sold? Not very often. And when it comes to porting your mortgage, if the value of the new home is higher than the outstanding balance on your existing mortgage, you will most likely have to take a blended rate on the new money, which could increase your payment. If the property value is considerably less, you might actually incur a penalty to reduce the total mortgage amount. If the value of the properties are different, the terms of your mortgage will be amended anyway!

  • You still need a downpayment.

Porting a mortgage isn't just a simple case of swap one property for the another and keep the same mortgage. You're still required to come up with a downpayment on the new property.

  • You will most likely have to pay a penalty.

When you sell your house, most lenders will charge the full penalty and take it from your sale proceeds of your property. They will of course refund it back to you when you execute the port and purchase the new property. So if you were relying on the proceeds of sale to come up with your downpayment on the property you are purchasing, you might have to make other arrangements.

  • Timelines almost never work out.

It's rarely a buyers and a sellers market at the same time. So although you may be able to sell your property overnight, you might not be able to find a suitable property to buy. Alternatively, you might be able to find many suitable properties to purchase while your house sits on the market with no showings. And when you do end up selling your property, and finding a new property to buy, chances are the closing dates won't match up perfectly.

  • Different lenders have different port periods.

This is where the fine print in the mortgage documents comes into play. Did you know that depending on the lender, the period of time you have to port your mortgage can range from 1 day to 6 months? So if it's 1 day, your lawyer will have to close both the sale of your property and the purchase of your new property on the same day, or the port won't work. Or with a longer port period, you run the risk of selling your house with the intention of porting the mortgage, only to not be able to find a suitable property to buy.

So as you can see, although porting your mortgage may make sense if you have a low rate that you want to carry over to a property of similar value, it is always a good idea to get professional mortgage advice and look at all your options.

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.

You’ve most likely heard that there are two certainties in life; death and taxes. Well, as it relates to your mortgage, the single certainty is that you will pay back what you borrow, plus interest. With that said, the frequency of how often you make payments to the lender is somewhat up to you! The following looks at the different types of payment frequencies and how they impact your mortgage. Here are the six payment frequency types Monthly payments – 12 payments per year Semi-Monthly payments – 24 payments per year Bi-weekly payments – 26 payments per year Weekly payments – 52 payments per year Accelerated bi-weekly payments – 26 payments per year Accelerated weekly payments – 52 payments per year Options one through four are straightforward and designed to match your payment frequency with your employer. So if you get paid monthly, it makes sense to arrange your mortgage payments to come out a few days after payday. If you get paid every second Friday, it might make sense to have your mortgage payments match your payday. However, options five and six have that word accelerated before the payment frequency. Accelerated bi-weekly and accelerated weekly payments accelerate how fast you pay down your mortgage. Choosing the accelerated option allows you to lower your overall cost of borrowing on autopilot. Here’s how it works. With the accelerated bi-weekly payment frequency, you make 26 payments in the year. Instead of dividing the total annual payment by 26 payments, you divide the total yearly payment by 24 payments as if you set the payments as semi-monthly. Then you make 26 payments on the bi-weekly frequency at the higher amount. So let’s use a $1000 payment as the example: Monthly payments formula: $1000/1 with 12 payments per year. A payment of $1000 is made once per month for a total of $12,000 paid per year. Semi-monthly formula: $1000/2 with 24 payments per year. A payment of $500 is paid twice per month for a total of $12,000 paid per year. Bi-weekly formula: $1000 x 12 / 26 with 26 payments per year. A payment of $461.54 is made every second week for a total of $12,000 paid per year. Accelerated bi-weekly formula: $1000/2 with 26 payments per year. A payment of $500 is made every second week for a total of $13,000 paid per year. You see, by making the accelerated bi-weekly payments, it’s like you end up making two extra payments each year. By making a higher payment amount, you reduce your mortgage principal, which saves interest on the entire life of your mortgage. The payments for accelerated weekly payments work the same way. It’s just that you’d be making 52 payments a year instead of 26. By choosing an accelerated option for your payment frequency, you lower the overall cost of borrowing by making small extra payments as part of your regular payment schedule. Now, exactly how much you’ll save over the life of your mortgage is hard to nail down. Calculations are hard to do because of the many variables; mortgages come with different amortization periods and terms with varying interest rates along the way. However, an accelerated bi-weekly payment schedule could reduce your amortization by up to three years if maintained throughout the life of your mortgage. If you’d like to look at some of the numbers as they relate to you and your mortgage, please don’t hesitate to connect anytime; it would be a pleasure to work with you.
