Budget roughly 4% to 7% of your sale price to sell a home in Oakville, before any mortgage penalty. The largest part of that — real estate commission — is fully negotiable in Ontario, with no fixed, standard, or required rate. The examples below use a sample commission of 4.5% plus 13% HST only to show the arithmetic, as other Oakville guides do. That sample is not The Fisher Group's rate; your rate is what you agree in writing in your listing agreement.
Who pays what, in plain terms
In most Oakville sales, the seller pays the total commission from the sale proceeds at closing, shared between the listing brokerage and the buyer's brokerage as set out in the listing agreement and MLS listing — unless that agreement says otherwise. Confirm the split before you list, because it affects how your listing is presented to buyer agents.
The seller also normally pays their own legal fees, mortgage discharge costs, and whatever they choose to spend preparing the home — cleaning, repairs, staging, and moving. The buyer pays their own costs, including land transfer tax and their own legal fees. Ask your lender early whether a mortgage prepayment penalty applies. Penalties vary widely, and for some sellers they exceed every other cost in this page combined — so they are excluded from the range above and from both tables below.
Tax is part of the bill, and it is easy to forget
Commission is subject to 13% Harmonized Sales Tax in Ontario, and so are legal fees. A sample commission of 4.5% is therefore an effective 5.085% of the sale price once HST is added — more than $8,000 of tax alone on an average-priced Oakville home, as the first example shows. In the usual resale case, HST is not charged on the home's sale price itself, unlike a new build. Your lawyer will confirm the tax treatment at closing.
Worked example one: a sale at the October 2026 Oakville average
The average Oakville sale price in October 2026 was $1,383,011, according to TRREB Market Watch. The table applies the sample commission, typical legal fees of $1,000 to $2,000 plus HST, and budget allowances for discharge, moving, and optional staging to that price. The allowances are not quotes — your costs depend on your lender, mover, and preparation choices.
Cost | How it is calculated | Amount |
|---|---|---|
Sample commission | 4.5% of $1,383,011 — example only, negotiable | $62,235 |
HST on commission | 13% of the sample commission | $8,091 |
Legal fees | $1,000–$2,000, plus 13% HST | $1,130–$2,260 |
Mortgage discharge and administration | Budget allowance; lender fees vary | $300–$500 |
Moving | Budget allowance; distance and volume vary | $1,000–$3,000 |
Preparation and staging (optional) | Budget allowance; $0 if you sell as-is | $0–$5,000 |
Estimated total, before mortgage penalty | Sample commission and HST, plus the lines above | $72,756–$81,086 |
That total is about 5.3% to 5.9% of the sale price, with commission and its HST accounting for most of it — which is why the commission conversation at listing time matters more than saving a few hundred dollars on preparation.
Worked example two: a detached sale at $1,700,000
Detached homes averaged $1,833,285 in October 2026, so this second example uses a round detached price of $1,700,000, with the same sample rate and allowances, to show how costs scale with price.
Cost | How it is calculated | Amount |
|---|---|---|
Sample commission | 4.5% of $1,700,000 — example only, negotiable | $76,500 |
HST on commission | 13% of the sample commission | $9,945 |
Legal fees | $1,000–$2,000, plus 13% HST | $1,130–$2,260 |
Mortgage discharge and administration | Budget allowance; lender fees vary | $300–$500 |
Moving | Budget allowance; distance and volume vary | $1,000–$3,000 |
Preparation and staging (optional) | Budget allowance; $0 if you sell as-is | $0–$5,000 |
Estimated total, before mortgage penalty | Sample commission and HST, plus the lines above | $88,875–$97,205 |
At $1,700,000, the total is again about 5.2% to 5.7% of the price, because commission is a percentage while the other costs are largely fixed. A quarter-point difference in commission is worth $4,250 before HST at this price.
Costs sellers often miss
Three items catch sellers out. The first is a mortgage penalty — confirm it before you set a closing date, not after you accept an offer. The second is getting ready: postponed repairs, a pre-listing inspection, or storage. The third is timing — Oakville homes averaged 37 days to sell in October 2026, at 95% of asking, so an asking price set too high can cost more in a later reduction than any fee here.
What this means for you
Ask every brokerage you interview the same questions, in writing. What is the total commission, how is it split with a buyer's brokerage, and what is included — photography, staging advice, marketing, open houses, and negotiation? Then compare the net you would keep at a realistic sale price, not just the headline rate. What matters is a clear agreement, a defensible price, and a plan to reach the buyers most likely to pay it.
Frequently asked questions
Is there a standard commission rate in Ontario?
No. Commission is fully negotiable, with no fixed, standard, or required rate. The 4.5% in this page is an arithmetic example only, not The Fisher Group's rate. Your rate is what you agree in writing in your listing agreement.
Who pays the buyer's agent in Ontario?
In most sales, the seller pays the total commission from the proceeds, shared between the listing and buyer's brokerages as set out in the listing agreement, unless that agreement says otherwise. Confirm the split before listing.
Do I pay HST when I sell my house?
You pay 13% HST on commission and on legal fees. In the usual resale case, HST is not charged on the home's sale price itself. On the $1,383,011 example, HST on the sample commission alone is $8,091.
How much are legal fees to sell a house in Oakville?
For a straightforward sale, typically $1,000 to $2,000 plus HST and disbursements, as in this page's examples. A tenanted home, a title issue, or a same-day purchase can cost more. Ask your lawyer for a written estimate.
What else should I budget for besides commission?
Legal fees and HST, discharge and administration, moving, and any preparation or staging you choose — $300 to $500, $1,000 to $3,000, and $0 to $5,000 in these examples. Also ask your lender about a prepayment penalty, which is outside the 4% to 7% range.
Can I save money by selling without an agent?
You would avoid some or all commission, but take on pricing, marketing, showings, negotiation, and paperwork yourself — and most buyers have an agent who will still expect to be paid. Compare the likely net, not just the fee saved.
