To finance a rental property in Ontario you need a minimum 20 percent down payment, because mortgage default insurance is not available on a property you do not live in. Lenders will count some of the expected rent toward your qualifying income, usually between 50 and 100 percent of it depending on the lender and how they calculate it. Most people fund that down payment with equity from the home they already own, using a refinance or a home equity line of credit.
That is the short answer, and it is usually the point where people relax a little, because the down payment was the part they thought would be impossible. Let me walk you through the rest of it in plain words.
The down payment rule, and why it exists
On a home you live in, you can put down as little as 5 percent because default insurance protects the lender. That insurance simply does not apply to a property you are not living in. So the floor is 20 percent, full stop, on every rental purchase in Ontario.
Some lenders want more than 20 percent on certain properties. A small multi-unit building, a property in a very small town, or a place needing serious work can all push the requirement higher. Twenty percent is the minimum, not a guarantee.
Here is the part most people have not connected yet. That down payment does not have to come out of your savings account. If you have owned your home for a while, there is a good chance the money is already sitting in your walls.
Where the down payment usually comes from
Say a couple in Barrie bought their house about nine years ago. They have watched friends buy rentals and always assumed it was a thing other people did, because who has that kind of cash sitting around.
Then they actually looked at their equity. Nine years of payments plus nine years of market movement, and the number was considerably larger than either of them had guessed. Not a windfall, just the quiet result of paying a mortgage for almost a decade.
There are two common ways to turn that into a down payment.
A refinance. You replace your existing mortgage with a larger one and take the difference in cash. Your payment on your own home goes up, and you now have the down payment in hand. Clean and simple, and you know exactly what you borrowed.
A home equity line of credit. A HELOC is a revolving credit that works like a credit card secured by your house. You get approved for a limit, you draw only what you need, and you can pay it back whenever you like. Some people prefer this because they are not paying interest on the money until they actually buy something.
Both have trade-offs, and which one fits depends on your rate, your renewal date, and how quickly you plan to move. There is no universally right answer here, which is exactly why it is worth walking through your actual numbers with someone before you commit.
How lenders treat the rent
This is the piece that surprises people most, in a good way and a bad way.
The good news is that lenders do count rental income. The bad news is that they rarely count all of it. Two main approaches show up.
The offset method. The lender takes a percentage of the expected rent, often around 50 to 80 percent, and subtracts it from the property’s costs. Whatever is left over is the amount added to your monthly obligations. The haircut covers vacancy, repairs, and the months a tenant pays late.
The addition method. The lender adds a portion of the rent straight into your gross income and then runs their usual ratios.
Different lenders use different methods and different percentages, and the gap between them can decide whether your file gets approved. This is one of those situations where walking into a single bank and accepting their answer costs people real opportunities. A file that is a no at one lender is frequently a yes at another, purely because of how they do this one calculation.
They will usually want proof of the rent, either a signed lease if there is a tenant in place, or a market rent appraisal if the place is empty.
What the lender looks at besides the rent
Your rental property application is judged on more than the property itself.
Your credit matters, and rental financing usually asks for a stronger score than a purchase you will live in. Your income still has to support the whole picture, including the mortgage on your own home. Your down payment source needs to be documented, so if it is coming from a HELOC, that gets disclosed, not hidden. And the property type matters, since a standard single-family home in Barrie is far easier to finance than a rural property on a private road with a shared well.
Cash reserves help too. A lender likes to see you could carry an empty unit for a couple of months without panic, and honestly, so should you.
The numbers to run before you fall in love with a listing
Rent minus the mortgage payment is not your profit. Not close. Before you make an offer, put real numbers against all of these.
Property tax, insurance (which costs more on a rental than on your own home), utilities if you are covering them, condo fees if there are any, repairs and maintenance, property management if you are not doing it yourself, and a vacancy allowance because no unit is rented 365 days a year forever.
Then there is the tax side. Rental income is taxable, some expenses are deductible, and capital gains will apply when you eventually sell. That is a conversation for an accountant, and it should happen before you buy rather than after.
If the property only works on paper when every single thing goes right, it does not work. A good rental has room in it for the furnace that dies in February.
The order I would go in
1. Find out what your current home is actually worth today, not what you assume.
2. Work out your real equity position and what could safely come out of it.
3. Get clear on how much you would qualify for with rental income included, before you shop.
4. Build the full carrying-cost budget for the kind of property you are considering.
5. Then, and only then, start looking at listings.
Doing it in that order means you shop with a number instead of a hope, and you find out what is possible before you get emotionally attached to a place.
Common questions
How much down payment do I need for a rental property in Ontario?
At least 20 percent. Some lenders and some property types require more, particularly multi-unit buildings, rural properties, or homes needing significant work.
Can I use my home equity for the down payment on a rental?
Yes, and this is how most people do it. A refinance or a HELOC on your current home can provide the funds. The lender will want to know the money came from there, so be upfront about it.
Does rental income help me qualify?
Usually yes, partially. Most lenders count somewhere between 50 and 100 percent of the expected rent, and the exact treatment varies a lot between lenders. That variation is often the difference between an approval and a decline.
Are rental property mortgage rates higher?
Generally they carry a premium over a mortgage on the home you live in, since the lender is taking on more risk. The size of that premium varies by lender and by your overall file.
Can I get a rental property mortgage if I am self-employed?
Yes. It usually takes more documentation and sometimes a different lender, but self-employed borrowers buy rentals all the time. It is a matter of matching your file to a lender who understands it.
