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

Lisa Manwaring • November 20, 2019

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!

Porting your mortgage is when you transfer the remainder of your current mortgage term, outstanding principal balance, and interest rate to a new property if you’re selling your existing home and buying a new one. Now, despite what some 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 to purchase a new property using the mortgage you had on a previous property. In addition to re-qualifying for the mortgage you already have, the lender will also assess the property you’re looking to purchase. Many moving parts come into play. You’re more likely to have significant setbacks throughout the process than you are to execute a flawless port. Here are some of the reasons: You may not qualify for the mortgage Let’s say you’re moving to a new city to take a new job. If you’re relying on porting your mortgage to buy a new property, you’ll have to substantiate your new income. If you’re on probation or changed professions, there’s 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 isn’t an issue and that you qualify for the mortgage. The subject property you want to purchase has to be approved as well. Just because the lender accepted your last property as collateral for the mortgage doesn’t mean the lender will accept the new property. The lender will require an appraisal and scrutinize the condition of the property you’re looking to buy. Property values are rarely the same Chances are, if you’re selling a property and buying a new one, there’ll be some price difference. When looking to port a mortgage, if the new property’s value is higher than your previous property, requiring a higher mortgage amount, you’ll 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 incur a penalty to reduce the total mortgage amount. You still need a downpayment Porting a mortgage isn’t just a simple case of swapping one property for another while keeping the same mortgage. You’re still required to come up with a downpayment on the new property. You’ll most likely have to pay a penalty Most lenders will charge the total discharge penalty when you sell your property and take it from the sale proceeds. The penalty is then refunded when you execute the port and purchase the new property. So if you are relying on the proceeds of sale to come up with your downpayment, you might have to make other arrangements. Timelines rarely work out When assessing the housing market, It’s usually a buyer’s market or a seller’s market, not both 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 may be able to find many suitable properties to purchase while your house sits on the market with no showings. And, chances are, when you end up selling your property and find a new property to buy, the closing dates rarely match up perfectly. Different lenders have different port periods Understanding that different lenders have different port periods is where the fine print in the mortgage documents comes into play. Did you know that depending on the lender, the time you have to port your mortgage can range from one day to six months? So if it’s one 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 more extended 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 while the idea of porting your mortgage can seem like a good idea, and it might even make sense if you have a low rate that you want to carry over to a property of similar value, it’s always a good idea to get professional mortgage advice and look at all your options. While porting your mortgage is a nice feature to have because it provides you with options, please understand that it is not a guarantee that you’ll be able to swap out properties and keep making the same payments. There’s a lot to know. If you’re looking to sell your existing property and buy a new one, please connect anytime. It would be a pleasure to walk you through the process and help you consider all your options, including a port if that makes the most sense!

If you’re looking to purchase a property, although you might not think it matters too much, the source of your downpayment means a great deal to the lender. Let’s discuss the lender requirements, what your downpayment tells the lender about your financial situation, a how downpayment helps establish the mortgage loan to value. Anti-money laundering Lenders care about your downpayment source because, legally, they have to. To prevent money laundering, lenders have to document the source of the downpayment on every home purchase. Acceptable forms of downpayment are money from your resources, borrowed funds through an insured program called the FlexDown, or money you receive as a gift from an immediate family member. To prove the funds are from your resources and not laundered money from the proceeds of crime, you’ll be required to provide bank statements showing the money has been in your account for at least 90 days or that you’ve accumulated the funds through payroll deposits or other acceptable means. Now, if you’re borrowing all or part of your downpayment, you’ll need to include the costs of carrying the payments on the borrowed downpayment in your debt service ratios. If you’re the recipient of a gift from a direct family member, you’ll need to provide a signed gift letter indicating that the funds are a true gift and have no schedule for repayment. From there, you’ll need to show the money deposit into your account. Financial suitability Lenders care about the source of the downpayment because it is an indicator that you are financially able to purchase the property. Showing the lender that your downpayment is coming from your resources is the best. This demonstrates that you have positive cash flow and that you’re able to save money and manage your finances in a way that indicates you’ll most likely make your mortgage payments on time. If your downpayment is borrowed or from a gift, there’s a chance that they’ll want to scrutinize the rest of your application more closely. The bigger your downpayment, the better, well, as far as the lender is concerned. The way they see it, there is a direct correlation between how much money you have as equity to the likelihood you will or won’t default on their mortgage. Essentially, the more equity you have, the less likely you will walk away from the mortgage, which lessens their risk. Downpayment establishes the loan to value (LTV) Thirdly, your downpayment establishes the loan to value ratio. The loan to value ratio or LTV is the percentage of the property’s value compared to the mortgage amount. In Canada, a lender cannot lend more than 95% of a property’s value. So, if you’re buying a home for $400k, the lender can lend $380k, and you’re responsible for coming up with 5%, $ 20k in this situation. But you might be asking yourself, how does the source of the downpayment impact LTV? Great question, and to answer this, we have to look at how to establish property value. Simply put, something is worth what someone is willing to pay for it and what someone is willing to sell it for. Of course, within reason, having no external factors coming into play. When dealing with real estate, an appraisal of the property will include comparisons of what other people have agreed to pay for similar properties in the past. You’ll often hear of situations where buyers and sellers try to inflate the sale price to help finalize the transaction artificially. Any scenario where the buyer isn’t coming up with all of the money for the downpayment, independent of the seller, impacts the LTV. All details of a real estate transaction purchase and sale have to be disclosed to the lender. If there’s any money transferring behind the scenes, this impacts the LTV, and the lender won’t proceed with financing. Non-disclosure to the lender is mortgage fraud. So there you have it; hopefully, this provides context to why lenders ask for documents to prove the source of your downpayment.
