5 Things You Need to Know Before You Co-Sign a Mortgage!

Diane Buchanan • August 16, 2018

So you’re thinking about co-signing for a mortgage? Okay, do you really know what that means do you know what you are getting yourself into? Co-signing isn’t necessarily a bad thing, but there is certainly a lot of misinformation floating around on the subject. Although its nice to be in a position to help someone close to you qualify for a mortgage, It’s not a decision that should be made lightly. Co-signing on a mortgage could have a significant impact on your future.

Here are some things you should consider before co-signing a mortgage application. 

1. Regardless if you’re the principal borrower, co-borrower, or co-signor, If you’re on the mortgage, you’re 100% responsible for the debt of the mortgage and everything that goes along with that. Although the term co-signor makes it sound like you are somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage. 

2. If the person who you’re co-signing for is unable to make the payments for any reason, you will be expected to make them on their behalf. By signing the mortgage documents, you assume full responsibility for the payments (even if it’s not you making them). 

3. If payments aren’t being made, there is a chance the lender will take legal action against you. This includes all available collection methods such as obtaining a judgement in court or garnisheeing your wage or bank accounts. Worse case scenario, they could actually go after your property or assets in order to cover their loses. Now, this is highly unlikely, but not out of the realm of possibility. 

4. Once the initial term has been completed, you will not automatically be removed from the mortgage. The person who you co-signed for will have to make a new application for the mortgage in their own name and qualify on their own merit. If they don’t qualify at this time, you will be kept on the mortgage for the next term. 

5. When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted against you. This means that if you’re looking to buy another property in the future, you will have to include the payments of the co-signed mortgage in your debt service ratios, even though you aren’t the one making the payments. This could significantly impact the amount you can borrow in the future. 

If you have any questions about co-signing on a mortgage, or about the mortgage application process in general, I’d love to discuss it with you. Please don’t hesitate to contact me anytime!

Thinking About Selling Your Home? Start With These 3 Key Questions Selling your home is a major move—emotionally, financially, and logistically. Whether you're upsizing, downsizing, relocating, or just ready for a change, there are a few essential questions you should have answers to before you list that "For Sale" sign. 1. How Will I Get My Home Sale-Ready? Before your property hits the market, you’ll want to make sure it puts its best foot forward. That starts with understanding its current market value—and ends with a plan to maximize its appeal. A real estate professional can walk you through what similar homes in your area have sold for and help tailor a prep plan that aligns with current market conditions. Here are some things you might want to consider: Decluttering and removing personal items Minor touch-ups or repairs Fresh paint inside (and maybe outside too) Updated lighting or fixtures Professional staging Landscaping or exterior cleanup High-quality photos and possibly a virtual tour These aren’t must-dos, but smart investments here can often translate to a higher sale price and faster sale. 2. What Will It Actually Cost to Sell? It’s easy to look at the selling price and subtract your mortgage balance—but the real math is more nuanced. Here's a breakdown of the typical costs involved in selling a home: Real estate agent commissions (plus GST/HST) Legal fees Mortgage discharge fees (and possibly a penalty) Utility and property tax adjustments Moving expenses and/or storage costs That mortgage penalty can be especially tricky—it can sometimes be thousands of dollars, depending on your lender and how much time is left in your term. Not sure what it might cost you? I can help you estimate it. 3. What’s My Plan After the Sale? Knowing your next step is just as important as selling your current home. If you're buying again, don’t assume you’ll automatically qualify for a new mortgage just because you’ve had one before. Lending rules change, and so might your financial situation. Before you sell, talk to a mortgage professional to find out what you’re pre-approved for and what options are available. If you're planning to rent or relocate temporarily, think about timelines, storage, and transition costs. Clarity and preparation go a long way. The best way to reduce stress and make confident decisions is to work with professionals you trust—and ask all the questions you need. If you’re thinking about selling and want help mapping out your next steps, I’d be happy to chat anytime. Let’s make a smart plan, together.

As patios wind down and pumpkin spice ramps up, fall is the perfect reset for your home—and your homeowner game plan. These quick wins boost comfort, curb appeal, and efficiency now, and set you up for a low-stress winter (and a strong spring market). 1) Safety & “silent leak” checks (Weekend-ready) Clean gutters & downspouts. Add leaf guards where trees overhang. Roof scan. Look for lifted shingles, cracked flashings, or moss. Seal the shell. Re-caulk window/door trim; replace weatherstripping. Test alarms. New batteries for smoke/CO detectors; add one near bedrooms. Why it matters: Prevent water intrusion and heat loss before storms roll in. 2) Heat smarter, not harder Furnace/boiler tune-up and filter change. Smart thermostat with schedules and geofencing. Draft hunt. Foam gaskets behind outlets, door sweeps on exterior doors. ROI tip: Efficiency upgrades lower monthly bills and can improve lender ratios if you’re eyeing a refinance later. 3) Fall-proof your yard (so spring you says “thanks”) Aerate + overseed + fall fertilize for thicker turf next year. Trim trees/shrubs away from siding and power lines. Mulch perennials and plant spring bulbs now. Shut off/bleed exterior taps and store hoses to avoid burst pipes. 4) Extend outdoor season (cozy edition) Portable fire pit or propane heater + layered blankets. Path/step lighting for darker evenings (solar or low-voltage). Weather-resistant storage for cushions/tools to preserve value. Neighborhood curb appeal: Warm lighting and tidy beds make a big first impression if you list in shoulder season. 5) Water management = winter peace of mind Re-grade low spots and add downspout extensions (2–3+ metres). Check sump pump (and backup). Look for efflorescence or damp corners in the basement. 6) Mini-renos that punch above their weight Entry/mudroom upgrade: hooks, bench, boot trays, closed storage. Laundry room tune-up: counter over machines, sorting bins, task lighting. Kitchen refresh: new hardware, tap, and under-cabinet lighting in one afternoon. Budget guide: Many of these land under a micro-reno budget—perfect for a modest line of credit. 7) Indoor air quality tune-up Deep clean vents and dryers (including the rigid duct). Add door mats (exterior + interior) to catch grit/salt. Houseplants or HEPA purifier for closed-window months. Fast Timeline (pin this to the fridge) Late August–September Gutters/downspouts, roof/caulking, HVAC service, lawn care, plant bulbs, exterior tap shut-off plan, path lighting. October Weatherstripping/sweeps, fire pit setup, organize mudroom/garage, test alarms, sump check, downspout extensions, dryer vent cleaning. Financing smarter: make your mortgage work for your home Annual mortgage check-in. As rates, income, and goals evolve, a quick review can free up cash flow or open options for a small fall project budget. HELOC vs. top-up refinance. For bite-size projects, a HELOC can be flexible. For bigger renos you plan to pay down, a top-up refi might make more sense. Bundle & prioritize. Knock out the high-impact, low-cost items first (air sealing, safety, water management) before the cosmetic upgrades. Not sure which route fits your fall plans? We’ll run the numbers and map the best financing path for your specific budget and goals.
