New Mortgage Rules 2018 Ontario Calculator

Ontario's mortgage rules changed significantly in 2018, affecting interest rates, down payments, and mortgage insurance. This calculator helps you understand how these changes impact your mortgage options and costs.

Introduction

In 2018, Ontario implemented several changes to its mortgage regulations that significantly affected homebuyers and investors. These changes included:

Stricter mortgage stress tests
Lower maximum loan-to-value ratios for certain properties
Changes to mortgage insurance requirements
New rules for variable-rate mortgages

These changes were designed to improve financial stability in the housing market but created challenges for many borrowers. This calculator helps you understand how these rules affect your specific mortgage situation.

Key Changes in 2018

Stricter Mortgage Stress Tests

The most significant change was the introduction of stricter mortgage stress tests. Under the new rules, lenders must verify that borrowers can afford their mortgage payments even if interest rates rise by 2 percentage points.

Lower Loan-to-Value Ratios

For certain types of properties, the maximum loan-to-value ratio was reduced. For example, condominiums and townhouses now have lower maximum LTVs than single-family homes.

Mortgage Insurance Changes

Mortgage insurance requirements were modified. Borrowers with down payments below 20% now face different insurance premiums, and some lenders may require mortgage insurance even for larger down payments.

Variable-Rate Mortgage Rules

New rules were introduced for variable-rate mortgages, including stricter qualification requirements and more frequent rate reviews.

How This Calculator Works

This calculator uses the following formula to determine your mortgage eligibility under the 2018 rules:

Mortgage Eligibility = (Income × 4.5) × (1 - (Down Payment / Purchase Price))

Where:

Income = Your annual gross income
Down Payment = Your initial down payment amount
Purchase Price = The total price of the property

The calculator then compares this amount to the maximum mortgage amount allowed under Ontario's 2018 rules, considering your property type and credit score.

Note: This calculator provides an estimate. Actual mortgage eligibility depends on your specific financial situation and the lender's underwriting criteria.

Example Calculation

Let's look at an example to understand how the calculator works:

Scenario

Annual income: $80,000
Down payment: $40,000
Purchase price: $300,000
Property type: Single-family home
Credit score: 720

Calculation Steps

Calculate maximum mortgage amount: (80,000 × 4.5) × (1 - (40,000 / 300,000)) = $360,000 × 0.8667 = $312,000
Adjust for property type and credit score (assuming 90% of maximum amount is allowed): $312,000 × 0.9 = $280,800
Compare to actual mortgage amount: $300,000 - $40,000 = $260,000

In this example, the borrower would qualify for the mortgage under the 2018 rules.
