For a lot of Ontario homeowners, one single asset holds almost everything they own, and that asset is the house they live in. Diversifying means deliberately making sure your wealth is not all riding on one property in one town, usually by building liquid savings, clearing expensive debt, and holding some investments outside the walls. Borrowing against your home to invest is only one version of this, it carries real risk, and it is rarely the first step anyone should take.
Let me explain what this actually looks like for a real household, because the word diversify sounds like something for people with a wealth manager, and it really is not.
The quiet math nobody runs
Picture Sarah. She is 47, lives just outside Barrie, and bought her house twelve years ago. She has a mortgage that is well along, a car loan, a couple of credit cards that crept up over a few slow winters, and about eight thousand dollars in savings that she thinks of as the emergency fund.
Sarah does not feel wealthy. She feels tight. Money is stressful every single month.
Then we sit down and list what she owns. The house has gone up a lot in twelve years, so let’s say it is worth somewhere around $700,000 with roughly $300,000 still owing. Round, illustrative numbers, kept simple on purpose. That is about $400,000 of equity sitting in the walls.
So Sarah has around $400,000 in one asset and about $8,000 in everything else. Give or take, more than ninety-eight percent of her net worth is a single house on a single street in a single market. That is the number that stops the room, every time.
She did nothing wrong here. Her house quietly got valuable while she was busy raising kids and going to work. Nobody sent her a statement about it, so it never entered her planning.
Why one big asset is riskier than it feels
A paid-for house feels like the safest thing in the world. There are three reasons the picture is more complicated.
It is not liquid
You cannot sell the spare bedroom. Equity is real wealth, and it is stuck in a form you cannot spend without either selling the whole thing or borrowing against it. When the furnace dies in February, four hundred thousand dollars of equity does not help you unless you already set up a way to reach some of it.
It is one market, not the market
Your home value depends on your town, your street, your property type, and what happens locally. A single property has no internal diversification at all. Values in Simcoe County have moved in both directions in recent years, and anyone who watched 2022 and 2023 saw that a home price is not a one-way escalator.
The timing is not yours to choose
Concentration hurts most when you are forced to act at a bad moment. A job change, a health event, or a separation can put you in the position of needing to sell or borrow exactly when the market or your own qualifying picture is weakest. Spreading things out gives you options in the moments you have the least control.
What diversifying actually means for a homeowner
Here is where people expect me to say “borrow against your house and invest it.” That is one narrow version, it suits a small number of people, and it belongs near the end of the list rather than the beginning. The honest order looks more like this.
Clear the expensive debt first. No investment reliably beats the guaranteed return of getting rid of a balance costing you nineteen or twenty-something percent. Sarah’s credit cards are the highest-return “investment” available to her, and it is not close. Consolidating that into her mortgage or a home equity line of credit, meaning a revolving credit that works like a credit card secured by your house, can free up real monthly cash flow.
Build cash you can actually touch. A few months of expenses in a plain savings account is diversification in its truest sense, because it is money that exists outside the house and does not require anyone’s approval. This is boring and it is the step that changes the most lives.
Set up liquidity before you need it. A HELOC approved and left at a zero balance costs very little and gives you access to your own equity on a bad day. Lenders qualify you on income, so the easy time to arrange it is while you are working and your file looks strong, not in the middle of the emergency.
Then, and only then, look at investing outside the walls. RRSPs, TFSAs, and non-registered investments all put money somewhere your house is not. That belongs in a conversation with a financial planner or an accountant, and I am glad to be part of that conversation rather than the whole of it.
Watch out for the fake diversification. Buying a second property with equity from the first feels like spreading out, and it often means owning two pieces of the same regional real estate market with more leverage. Rentals and cottages can be smart moves for the right family. Just call them what they are.
The part I will not soften
Borrowing against your home to invest is a real strategy with real math behind it, and it is also how people get hurt. Your investment can fall while your loan payment stays exactly the same. Rates can move. Your income can change. Anyone considering it needs a long time horizon, stable income, a genuine tolerance for watching a balance drop, and proper advice from someone licensed to give investment advice.
If a plan only works when everything goes right, it is not a plan.
The gentler version of this principle is the one I actually give most people. Try not to let one asset carry your entire financial life, and start by making the rest of the picture stronger rather than by taking more risk.
Where to start this week
Write down three numbers: a realistic value for your home, what you still owe, and everything else you have saved or invested. Two minutes, back of an envelope.
If that third number is tiny next to the first two, you have found the thing worth working on, and there is nothing shameful about it. Almost every homeowner I meet is in exactly that position, woohoo. Knowing it is the whole start.
Frequently asked questions
Is it bad to have all my money in my house?
It is common rather than catastrophic, and it does carry real concentration risk. Your wealth sits in one illiquid asset tied to one local market, so a job loss or an emergency can force a decision at the worst possible time. Building savings and clearing high-interest debt usually reduces that risk faster than any borrowing strategy.
Should I borrow against my home to invest?
Sometimes, for a narrow group of people, and it should almost never be the first step. Leverage magnifies both gains and losses, your payment continues even when markets fall, and it requires a long horizon plus stable income. Speak with a licensed financial advisor as well as a mortgage professional before going near it.
What does diversifying mean for a regular homeowner?
Making sure meaningful value exists outside your house. That typically means an accessible cash buffer, paying off expensive consumer debt, contributions to registered accounts like a TFSA or RRSP, and having a way to reach some equity if you need it.
Does buying a rental property count as diversifying?
Partly. You add a second income stream and a second asset, and you also add more real estate exposure, often in the same region and with more leverage. Rentals can be a strong move, and they should be chosen with clear eyes about what they do and do not spread out.
How much of my net worth should be in my home?
There is no single correct percentage, and it depends on your age, income, and goals. The more useful question is whether you could handle a large surprise expense or a few months without income using something other than your house. If the answer is no, that is the gap worth closing first.
