First-Time Buyer Mortgage Rules You Must Know

By

Embarking on the journey to your first home is an exciting time, but navigating the mortgage landscape can be daunting. Understanding the rules and requirements for first-time buyer mortgages is crucial to ensuring a smooth sailing towards home ownership. This comprehensive guide will demystify the key rules and regulations you need to know as a first-time buyer.

Firstly, let's clarify who qualifies as a first-time buyer. According to Canada's housing agency, CMHC, a first-time buyer is someone who has not purchased a property before, or has not owned a property in the last four years. Now, let's dive into the key rules and requirements.

Mortgage Insurance

If you're putting down less than 20% of the purchase price as a down payment, mortgage insurance is a requisite. This insurance protects your lender in case you default on your loan. It's an important rule to understand as it adds to your closing costs.

In Canada, mortgage insurance is typically supplied by the Canada Mortgage and Housing Corporation (CMHC), Genworth Financial Canada, or Canada Guaranty. The premium varies based on the loan-to-value (LTV) ratio and is calculated as a percentage of your mortgage amount.

Minimum Down Payment

The minimum down payment for a first-time buyer is 5% of the property value for homes up to $500,000, 10% for amounts between $500,000 and $1,000,000, and 20% for amounts over $1,000,000. This is a significant rule to consider as it impacts the amount you need to save for your home purchase.

For instance, if you're buying a home worth $400,000, you would need to put down $20,000 (5%) as opposed to $40,000 (10%) if you'd decide on a $600,000 house.

GST/HST New Housing Rebate

As a first-time buyer, you may be eligible for a partial rebate of the GST or HST paid on the purchase price of new residential properties or newly constructed houses. This rule allows for a relief from the upfront taxes, making the homeownership process more affordable.

To qualify, first-time buyers must purchase or construct a new house, live in the house as their primary residence, and obtain legal ownership of the house. The rebate is calculated as a percentage of the GST or HST paid, and the exact amount depends on the location and type of property.

Income and Debt Servicing

Banks use two primary ratios - Gross Debt Servicing (GDS) and Total Debt Servicing (TDS) ratios - to determine your qualifications for a mortgage. Understanding these rules will give you a clear idea of how much mortgage you can afford.

GDS ratio compares your monthly housing costs (mortgage, property taxes, heating and utilities) to your gross monthly income. In Canada, this ratio should not exceed 32% for insured mortgages, or 29% for conventional mortgages. Meanwhile, the TDS ratio includes all your debt obligations (credit card payments, car loans, etc.) and your housing costs, and should not exceed 42% for insured mortgages, or 39% for conventional mortgages.

Mortgage Term and Amortization

Mortgage terms range from six months to 10 years, with the most common being five-year terms. The amortization period, typically 25 years, refers to the length of time it would take to pay off your entire mortgage, given a consistent repayment schedule. These time frames are pivotal rules to understand as they impact your interest rates and monthly payments.
