Buying a rental property? What you need to know about Rental Add-Back vs Rental Offset

Kelly Hudson • May 21, 2020

Add-backs and offsets are two different methods for accounting for the rental income from an investment property. 


If you are considering purchasing a rental property, understanding how add-backs and offsets work, is important when qualifying for your next mortgage.

Please note that regardless of the method used, lenders do not use 100% of the rental income, typically they use around 50%.

Rental Add-Back

Many lenders use the add-back method to account for the rental income on investment properties.

This means is that they will add a percentage of the rental income to the rest of your income. This will be used to calculate your ability to make payments on the rental mortgage and your other debts, hence the term add-back.

For example, if rent is $2000 a month ($24,000 per year) and the lender allows 50% add- back, therefore $12,000/year. An additional $12,000 income will not make a big difference to the amount of mortgage you can qualify for

Additional Mortgage available with $12,000 rental income (rule of thumb is 4-5 times) = $48,000-60,000 additional mortgage affordability

Rental Offset

In contrast, a Rental offset approach gives you more bang for your buck, since you can use a percentage of the rental income to offset (subtract from) your rental expenses.

A lender will typically use 50% of the rental income to offset the mortgage Principle, Interest and Tax mortgage payments (PIT) .

Therefore, if your rental property earns you $2,000 per month, and the lender will allow for 50% offset i.e. $1,000 to offset (subtract from) the PIT payment.

To see how this works, let’s assume PIT payments equal $1,200. Since you earn $2,000 in income, and the lender uses a 50% rental offset rule, you deduct $1,000 from the $1,200 PIT payment.

Therefore, only the $200/month difference must be covered by your other income.

With Rental add-back – the whole PIT $1200 for the rental property must be covered by your income (including the $12,000 rental income with 50% Add-back).

The bottom line is, it is very difficult to qualify for financing on rental properties using the 50% add-back rule, especially in areas like Vancouver or Toronto which have higher home prices.

Regrettably, there is no standard with lenders regarding Rental income. Some lenders use Rental Add-Back while others use Rental Offset rules.

To overcome this financing obstacle, you need to work with your mortgage broker to decide which lender(s) have the best rental options for your situation.

Getting a Mortgage After Separation or Divorce in Canada: What You Need to Know

By Kelly Hudson • February 14, 2025
Separation and divorce are major life events that significantly impact finances—including homeownership. In Canada, approximately 40% of marriages end in divorce , making it a common challenge for homeowners. As a mortgage broker, I work with many clients who are navigating the challenges of keeping or selling their home, refinancing, or qualifying for a new mortgage post-separation. Lenders assess these applications differently than standard ones, particularly when it comes to income, debts, and liabilities . Whether you want to stay in your current home or move on to a new one, understanding your mortgage options is essential. How Separation & Divorce Impact Your Mortgage When separating from a spouse, one of the biggest financial decisions is what to do with the family home. Here are some common scenarios: 1. Keeping the Home If one spouse wants to stay in the home, they must refinance the mortgage to remove the other person’s name from title and buy out their ex’s share of the equity. 2. Selling the Home In some cases, selling the home and splitting the proceeds is the best financial option. This provides a clean break but requires both parties to qualify for new mortgages if they wish to buy separate homes. 3. Co-Owning After Separation Some ex-partners choose to co-own the home for a period, often for the sake of stability for children. While this may work temporarily, it will complicate future borrowing power . 4. Existing Mortgage Responsibilities Even if a separation agreement states that one party is responsible for the mortgage, lenders will still consider both parties liable unless the mortgage is refinanced and the ex’s name is removed from the title & the mortgage. Important : If both names remain on the mortgage and your ex stops making payments, your credit score and future borrowing ability will be affected .

BC Property Assessment vs Home Appraisal (revised Jan16-2025)

By Kelly Hudson • January 21, 2025
What is BC Assessment? It’s January and in BC homeowners are receiving their property assessments. BC Assessment is a provincial Crown corporation that values all real estate property in British Columbia. Every year, BC Assessment sends property owners a Property Assessment Notice telling them the fair market value of their property as of July 1 the prior year . To see the most recent assessment for a property, click on BC Assessment and type in the property address. The real estate market is the single biggest influence on market values. Market forces vary from year to year and from property to property. The market value on an assessment notice may differ from that shown on a bank mortgage appraisal or a real estate appraisal because BC Assessment’s appraisal reflects the value as of July 1 of 2024 , while a private appraisal can be done at any time. The assessed values are based on limited information and are a result of algorithms and mass appraisal techniques which have their limitations. BC in general A new report forecasts the average price of B.C. home in 2025 at just over $1 million — the highest in Canada, some $280,000 above the national average. These figures appear in the latest forecast from the Canadian Real Estate Association released Jan. 15, 2025. Factors The increase in home prices was driven by a decrease in fixed mortgage rates and expectations for future Bank of Canada rate cuts. Use your BC Assessment as a starting point for the value of the property you’re planning to purchase… Do not rely on BC assessment for the exact value of the property you’re considering purchasing. Markets in BC change quickly both increasing and decreasing in value depending on the area and the economy.
