Oshawa mortgages, with the whole market in view.

What does Oshawa's market mean for buyers right now?

Short version: you have time and leverage. CLAR's September 2026 report shows 118 sales against 452 new listings, a sales-to-new-listings ratio of 26 percent and 5.64 months of inventory. Those are buyer's market conditions, and year-to-date average prices were down 8.31 percent.

That changes how I'd set up your financing. When sellers are negotiating, a buyer with a firm pre-approval and a rate hold can write a cleaner offer, ask for a longer closing or push on price without worrying the lender will move. I'd rather you spend your energy on the house than on wondering whether you'll qualify.

Detached homes made up 86 of the 118 sales in September, so much of what trades here is freehold. That matters for down payment planning, because the price you're shopping at decides which rules apply.

How much do I need down on an Oshawa home?

For a home under $1.5 million, the minimum is 5 percent of the first $500,000 and 10 percent of the portion above that, with mortgage default insurance. At $1.5 million and up, you need 20 percent down.

If you're a first-time buyer, or you're buying a new build, insured mortgages can stretch to a 30-year amortization, which lowers the payment you qualify on. Everyone else with less than 20 percent down is capped at 25 years. I'll show you both versions side by side so you can see what the extra five years costs in interest before you choose.

• Ontario's first-time buyer land transfer tax refund is worth up to $4,000. Oshawa has no municipal land transfer tax; only Toronto does.
• An FHSA lets first-time buyers save up to $40,000 over their lifetime, with deductible contributions and tax-free qualifying withdrawals.
• Buying new? Federal and Ontario rebates on new-home sales tax may apply. I'll flag them so your lawyer can confirm eligibility.

Oshawa's property tax rate and your approval

Lenders count property tax in your debt ratios, so it affects how much you can borrow. Oshawa's 2026 residential rate is 1.575342 percent, which works out to about $1,575 a year for every $100,000 of assessed value. It's the highest 2026 rate of the five Durham municipalities I cover, ahead of Clarington, Ajax, Whitby and Pickering.

That doesn't make Oshawa a worse buy. Prices here sit below much of Durham, and the tax difference is often smaller than the price gap. It just means I'll use the real tax figure for the property instead of a rough estimate, so your approval holds up when the lender underwrites it.

New builds in Kedron and a changing downtown

North Oshawa is where a lot of new supply is coming from. A City memo from February 2026 lays out the pipeline of new subdivisions in Kedron, and builder closings come with their own financing questions: deposit structures, closing dates that can slide, and appraisals that need to land at or near the purchase price.

Downtown is changing too. Medallion broke ground on the Foundry District on August 21, 2026, a 23-acre site with about 3,000 rental homes planned. The first two buildings bring more than 500 homes, 30 percent of them affordable. If you're thinking about an investment property nearby, a new supply of purpose-built rentals is worth factoring into your rent assumptions.

The City also adopted a Central Oshawa Community Improvement Plan in January 2026. It's aimed at developers, so it won't change a typical homeowner's mortgage, but it tells you where the City wants growth to go.

Getting around: the 401, the 407 and GO

Commuting shapes where people buy in Oshawa. The Durham College Oshawa GO station on the Lakeshore East line serves rail commuters, and the City describes Highway 407 East through Durham as toll-free, which matters if you're weighing a northern subdivision against something closer to the 401. A Central Oshawa GO station is planned as part of the Bowmanville extension, with no opening date published yet.

Renewing an Oshawa mortgage this year?

Start about four to six months before your maturity date. Many Oshawa homeowners who bought or refinanced in 2021 are renewing now, and the gap between the offer in your renewal letter and what the wider market offers can be meaningful. The Bank of Canada raised its policy rate to 2.50 percent on October 28, 2026, so a rate hold arranged early gives you some protection if rates keep moving.

If your mortgage is uninsured, a straight switch to a new lender at renewal doesn't require the stress test. That gives you real room to shop, even if your income or debts have changed since you first qualified. I'll line your renewal offer up against the market and show you the cost of each term before you sign anything.

Why talk to me before your bank?

Your bank can only offer its own products. I work with a range of lenders through my brokerage, so when one lender's rules don't fit your file, we have somewhere else to go. That's useful in Oshawa, where I see shift workers, people with commission or self-employed income, and buyers rebuilding credit.

Before mortgages, I worked as a correctional officer, so I understand rotating schedules, overtime and pensions, and how to present them to a lender. I'm also a real estate investor myself, which helps when you're buying a home with a rental unit or a property to hold.
