Yes. A first-time buyer in Hamilton can buy a triplex or fourplex, live in one unit and rent out the rest. The two big rules come from CMHC: you need at least 10% down, and the bank will count up to half of the rent from the other units to help you get the mortgage. On a Hamilton triplex at the median asking price of $799,900 in our Hamilton duplex, triplex and fourplex report, 10% down works out to $79,990.
That is more cash than a duplex needs, and the bank gives you less help from the rent. It still works for a lot of regular people. For comparison, the average freehold home in Hamilton sold for $737,420 in October 2026 in our Hamilton market report. So a triplex costs a little more than an average house, and it comes with two other homes inside it that pay rent.

How much cash a Hamilton triplex or fourplex really needs
The rules change at three units. With two units, the down payment works like a normal house. You put 5% down on the first $500,000 and 10% on the part above that.
At three or four units, it is 10% of the whole price. No 5% portion.
Here is what that looks like at the asking prices in our report, which come from the last 12 months of listings:
- Duplex, up and down: median asking $749,450. Down payment about $49,945.
- Triplex: median asking $799,900. Down payment $79,990.
- Fourplex: median asking $999,999. Down payment about $100,000.
Those are asking prices. A home can sell for less, or more. Homes in Hamilton took 40 days on average to sell in October 2026, which tells me most buyers have room to look and think before they make an offer.
The down payment is not your only cost. With less than 20% down, your mortgage needs CMHC insurance, which protects the bank. The fee for that is a share of the loan, and it gets added to your mortgage. You still need cash on hand for the lawyer, Ontario's land transfer tax, a home inspection and a cushion for repairs.
The takeaway: a Hamilton triplex needs about $30,000 more down than a duplex, so count your cash before you fall for a building.
How much of the rent the bank will count
This rule matters most, and few buyers know it before they start.
With a duplex, the bank can count up to 100% of the rent from the other unit when it works out what you can afford. With a triplex or fourplex, it can count only up to 50% of the rent, or the rent after costs. That is a choice your bank makes.
So why does more rent help less? The bank sees more units as more risk, more vacancies, more repairs and more work for one owner, and it takes the safe road by treating half the rent as if it may not show up.
Picture two friends who each make a steady wage and rent apartments in Hamilton. They find a triplex and plan to live in the main floor. The two upper units rent for an illustrative $1,600 each, so $3,200 a month comes in. The bank counts $1,600 of that toward their mortgage. That is enough to make the numbers work for them, because the rent still pays down a big share of the mortgage each month. The bank counted half. The tenants still pay all of it.
That last line is the real point. The 50% rule only changes what the bank will lend you. It does not change what lands in your account each month.
Why the fourplex price per unit can fool you
On paper, a fourplex looks like the better deal. Our report shows a median of $250,000 per unit for a Hamilton fourplex, against $266,633 per unit for a triplex and $374,725 for an up-and-down duplex. Each unit is cheaper.
But you need $100,000 down, and the bank still counts only half the rent. For many first-time buyers, that cash is the wall.
There is also less to pick from. Our report counts 28 fourplex listings in Hamilton over 12 months, against 68 triplexes and 117 up-and-down duplexes. Fewer choices means you may wait a long time for the right one.
A fourplex also has a tenant rule that catches buyers off guard. See the questions below.
My view? For most first-time buyers in Hamilton, the triplex is the sweet spot. It costs less cash than a fourplex, gives you two rents in place of one, and there are enough of them listed to compare. If you want to run the full numbers yourself, our underwriting standard shows how we work out costs as a share of rent, plus a prompt you can paste into an AI assistant.
Make sure every unit is legal before you fall for it
A lot of Hamilton multiplexes are old houses that were split into units years ago. Some were done with permits. Some were not.
The bank only counts rent from a unit that is legal. If the third unit is a basement suite nobody ever got approved, the bank may treat your triplex as a duplex. Then your 50% rent help shrinks, and your plan can fall apart a week before closing.
Older converted houses can also need fire safety work, like fire separations between units and the right smoke alarms. Those fixes can cost real money. They are worth pricing before you firm up an offer, and much harder to argue about after.
One thing I always ask for in writing on any income property: copies of the current leases and proof the rent actually gets paid. A listing can say "$1,600 a month" for a unit that a tenant has paid late half the year, and the leases tell you what you are really buying.
You also need one unit empty, or a clear plan to get one, because you have to live there. That is the whole point of house hacking, and it is what lets you buy with 10% down in place of 20%.
Where to start looking in Hamilton
Triplexes and fourplexes are not spread evenly across the city. You will find many more of them in the older parts of the lower city than in newer suburbs like Binbrook or Waterdown, where most homes were built as single houses.
Our multiplex report breaks the asking price per unit down by neighbourhood, so you can see where a duplex or triplex costs less per door. Our page on Hamilton investment properties covers which areas tend to hold their value and what landlords there deal with day to day.
Pick the area you would actually want to live in. You will be there every day, not just collecting rent.
Questions people ask
Can I buy a fourplex and ask a tenant to leave so I can move in?
Usually not. In Ontario, a buyer can ask a tenant to leave for their own use only when the building has three or fewer units. With a fourplex, you need a unit that is already empty or that a tenant leaves on their own. With a triplex, the rule can work, but the tenant gets notice and one month's rent as payment.
Is there a price limit on a triplex I buy with 10% down?
Yes. A home bought with less than 20% down needs CMHC insurance, and that insurance is only available on homes priced under $1.5 million. Every median asking price in our Hamilton multiplex report sits well under that line. The insurance fee goes on top of your mortgage, so you do not pay it in cash.
Does it matter if I live in the best unit or the worst one?
For the bank, no. It only needs you to live in one of the units. For your wallet, it often makes sense to live in the smaller unit and rent out the larger ones, because bigger units usually bring in more rent. Many owners move into the best unit later, once the mortgage is smaller.
