Key takeaways
  • You can usually borrow up to 80% of your home's value, minus what you still owe.
  • When you borrow against your home, the home is the security, and if you cannot repay you may lose it through foreclosure.
  • Breaking your current mortgage can trigger a penalty, and a second mortgage usually carries a higher rate.

If you are carrying credit card balances, a tax bill or other debts, rolling them into your mortgage can look attractive. One payment, and often a lower interest rate than a credit card.

But the trade is serious. Debts that were not tied to your house become debts secured on it. This article explains how it generally works in Ontario, what limits apply, and what to weigh before you sign.

How debt consolidation through your home works

There are two common routes. You can refinance, which replaces your current mortgage with a larger one and uses the extra money to pay off other debts. Or you can borrow against your equity without replacing the first mortgage, for example with a second mortgage.

A second mortgage is a second loan secured on your home. You must keep paying the first mortgage too, and second-mortgage interest rates are usually higher because they are riskier for lenders.

How much can you borrow?

When borrowing against home equity, you can usually borrow up to 80% of your home's value, minus what you still owe. The lender will also look at your income and credit, so being allowed to borrow is different from being able to afford it.

As a simple way to picture it, take 80% of your home's value and subtract what you still owe on your mortgage. What is left is the room you may have to borrow. Your lender's own calculations may differ.

If you are 55 or older, a reverse mortgage is a different product. It usually allows borrowing generally up to 55% of the home's current value, the interest is added to the loan so the balance grows, and the loan comes due when you sell, move out, the last borrower dies, or you default.

The risks to weigh

Choosing a lender or broker carefully

If your credit is strained, a private lender may be the only option. Private mortgages are generally a short-term option, often for one or two years. They are often interest-only, fees are often higher than for a traditional mortgage, and private lenders may charge fees for late payments, lapsed insurance or property upkeep. You should have an exit strategy and consider independent legal advice before signing.

Mortgage brokerages, brokers, agents and administrators in Ontario are licensed by FSRA under the Mortgage Brokerages, Lenders and Administrators Act, 2006, and you can check a licence on FSRA's public listing. You may not be protected if you deal with unlicensed people.

A brokerage must take reasonable steps to make sure any mortgage it presents is suitable for your needs and circumstances. It must disclose material risks in writing, its relationship with each lender and any conflict of interest, and it must get your written acknowledgement. These disclosures must be made no later than two business days before you sign the mortgage agreement.

Be wary of any loan with an extremely high cost of borrowing. It is a criminal offence to enter into or receive interest at a criminal rate, an annual percentage rate above 35 per cent. Certain commercial loans to borrowers who are not natural persons are exempt.

Credit card debt, tax debt and what to do next

Credit card debt and tax debt are not the same. Whether your tax debt can be paid from mortgage money, and whether other options exist, depends on the facts, so confirm the details with an accountant or a lawyer. Do not pay off a debt until you have the payout figure in writing.

Frequently asked questions

How much of my home's value can I borrow?

You can usually borrow up to 80% of your home's value, minus what you still owe. Lenders also assess your income and credit, so the amount you are offered may be lower.

Can I lose my home if I consolidate and then cannot pay?

Yes, that is the main risk. The home is the security, and if you cannot repay you may lose it through foreclosure. Credit card debt that has been rolled into the mortgage becomes part of that secured debt.

Will I pay a penalty to refinance?

Possibly. If you break your mortgage contract, the penalty is usually the higher of three months' interest on what you still owe or the interest rate differential. Ask for the exact figure before you decide.

Is a second mortgage cheaper than refinancing?

Not necessarily. Second-mortgage interest rates are usually higher because they are riskier for lenders, and you must keep paying the first mortgage too. Compare the total cost of both routes, including any penalty.
