What Sellers Actually Get Wrong

Most sellers walk into the process thinking the hard part is finding a buyer. It’s not. The hard part is everything you didn’t think about — the costs that eat into your profit, the timing decisions that can swing your net by tens of thousands of dollars, and the agent choice that shapes the entire experience. I’ve helped people sell across Toronto, Vaughan, Markham, and throughout York Region, and the mistakes I see repeat themselves almost exactly.

So here’s what I’d actually tell a friend who’s about to list.

Your costs are bigger than you think

Sellers fixate on the sale price. I get it — it’s the big exciting number. But the number that matters is what lands in your bank account after everything’s been paid, and most people have never actually done that math.

Let’s walk through it. On a $900,000 sale in the GTA, here’s a rough breakdown of what comes off the top:

Real estate commissions are typically the largest cost. In Ontario, commissions are negotiable — there’s no fixed rate — but you should expect this to be a meaningful line item. Make sure you understand exactly what you’re getting for what you’re paying. Ask your agent to break down their marketing plan, their reach, and what happens if the home doesn’t sell within a certain timeframe.

Legal fees will run you $1,500 to $2,500, sometimes more depending on complexity. Your lawyer handles the title transfer, mortgage discharge, and a pile of paperwork you’ll be grateful someone else is dealing with.

Staging and prep costs — painting, minor repairs, professional cleaning, staging furniture — can add up to $3,000 to $8,000 depending on how much work the home needs. It’s tempting to skip this. Don’t. The return on a well-prepped home almost always exceeds the cost.

Mortgage penalties. If you’re breaking your mortgage early, this one can sting. A fixed-rate mortgage penalty is often calculated using the Interest Rate Differential, and I’ve seen penalties hit $10,000 to $15,000 on some files. Call your lender and get the exact number before you list. This should never be a surprise on closing day.

Add it all up and you’re often looking at $40,000 to $60,000 or more in total selling costs on a typical GTA home. That’s real money. If you don’t know these numbers going in, you can’t make good decisions about pricing, offers, or your next purchase.

Timing is strategy, not astrology

People love asking “when’s the best time to sell?” as if there’s a magic week in April that guarantees top dollar. It doesn’t work like that — but timing does matter, just not the way most people think.

Broadly, the spring market (late February through May) tends to bring the most buyer activity in the GTA. More listings come up, but more buyers come out too. Fall has a second wave. Winter is traditionally slower, though I’ve seen January listings in Vaughan and Richmond Hill do surprisingly well because there’s almost no competition.

But here’s what actually matters more than the season: your local inventory. If there are 15 detached homes for sale in your neighbourhood, you’re fighting for attention. If there are three, you have pricing power. I’d rather list in February with two competing listings than in April with twelve.

The other timing factor people underestimate is their own readiness. Rushing to list before your home is properly prepped because you heard “spring is hot” is a recipe for a mediocre result. A well-prepared home listed in October will almost always outperform a half-ready home listed in April. Right?

If you’re also buying, timing gets more complicated. Selling first gives you certainty on your budget but means you might need bridge financing or temporary housing. Buying first gives you a smooth move but adds pressure to sell. There’s no universally correct answer — it depends on your financial situation, your risk tolerance, and what the market’s doing at that specific moment.

Your agent choice matters more than you realize

This is the one that I think people get most wrong, and I say that knowing I have skin in the game. But here’s the honest truth: the gap between a good agent and a mediocre one isn’t small. It’s enormous. It shows up in your price, your timeline, your stress level, and your legal protection.

A lot of sellers pick an agent because they’re a friend of a friend, or because they got a flyer in the mail, or because someone promised the lowest commission. I understand all of those impulses, but none of them are a strategy.

What you should actually be evaluating:

Do they know your specific market? Selling a condo in downtown Toronto and selling a detached home in Newmarket are fundamentally different transactions. The buyer pools are different, the marketing channels are different, the negotiation dynamics are different. You want someone who’s done volume in your area, not someone who’s “willing to learn.”

What’s their actual marketing plan? Not a vague promise of “maximum exposure.” I mean: what platforms, what photography budget, what video, what buyer database, what pre-market strategy? If they can’t articulate this clearly, they don’t have one.

How do they handle multiple offers? How do they handle no offers? What’s their plan B? These are the questions that separate experienced agents from ones who’ve only worked in a hot market.

Interview at least two or three agents. Ask them to show you a recent listing they handled from start to finish. The way they walk you through that process tells you everything.

Frequently Asked Questions

What’s the single biggest cost most sellers forget about?

Mortgage penalties. People remember commissions and legal fees, but the penalty for breaking a fixed-rate mortgage early can be shockingly high. I always tell sellers to call their lender for the exact number before doing anything else. It changes the math on everything.

Should I sell before buying or buy before selling?

There’s no one-size-fits-all answer. Selling first is financially safer — you know exactly what you have to spend. Buying first is logistically smoother — you move once. If you have significant equity and a strong financial position, buying first with a longer closing can work. If you’re tighter on funds, sell first. Talk to your mortgage broker about your specific numbers before deciding.

How do I know if my agent is actually good?

Look at their track record in your specific area and price range. Ask them to walk you through a recent transaction — not the highlights, the whole thing including problems and how they solved them. Good agents talk about challenges and strategy. Weak agents talk about themselves and how great the market is.

Is it really worth investing in home prep before selling?

In almost every case, yes. The homes I see sell fastest and for the most money are the ones that were properly prepped before going live. You don’t need a full renovation — fresh paint, deep cleaning, decluttering, and professional staging go a long way. Think of it as a business investment: spend $5,000 to potentially gain $20,000 or more on your sale price.
