How much more does a renovated home sell for in Durham Region?

Start with the estate home

For an estate home, start with its present condition and a written scope of potential improvements. Compare the sale options with the estate trustee before committing to work.

In one real Durham case, 132 Winona Ave in Oshawa was worth about $546,000 as-is. After a $218,597 pre-sale renovation it sold for $980,000 in 2020.

What the industry research on dated versus renovated homes says, labelled as such

Independent studies, all US-based unless noted, point the same direction. Revive Real Estate’s April 2025 analysis of more than 1,200 completed pre-sale renovations reported an average of $145,000 in additional seller profit and a 112% average return on the renovation spend. Curbio’s 2022 report measured project-level returns across its markets: kitchen refreshes at 377 percent and hardwood floor refinishing at 348 percent. On the Canadian side, Royal LePage’s May 2022 survey of its brokers and agents put the average value a kitchen renovation can add at 20 percent of a home’s value and a bathroom at 16 percent. And the remodel-industry benchmark, the NAR and NARI Remodeling Impact Report (April 2025), shows the flip side: large projects recover less than they cost at sale, a complete kitchen renovation 60 percent of its cost by NARI members’ estimate. These studies cover different markets and scopes of work. They do not establish a return for a Durham estate home.

The dated-home discount on the other side of the ledger

The renovated premium is only half the gap; the dated discount is the other half. Zillow’s analysis of over two million 2024 listings found homes described as remodeled sold at a 3.7 percent premium, the highest of any listing keyword, while fixer-uppers sold 7.3 percent below comparable homes, and Zillow’s March 2026 study of 2025 listings put the fixer-upper discount at 14 percent. Off the open market the discount is contractual: many cash buyers and flippers price with the 70 percent rule, a common guideline among house flippers (HomeLight, September 2026), an offer of no more than 70 percent of the after-repair value minus repair costs, which is why the three-way comparison treats a private cash sale as the most expensive convenience an estate can buy. Demand data explains the spread: 77 percent of buyers in Curbio’s survey would not consider a home that is not move-in ready.

What this means for a Durham estate home

Estate homes are disproportionately the dated ones, decades of ownership, original kitchens, and they sit at the wide end of the gap. For an executor (estate trustee), that gap is not just money, it is duty: the obligation to pursue fair market value, documented. The honest first step costs nothing: measure the gap for the specific home, an as-is value and an after-renovation projection side by side, and then decide with both numbers on the table. Sometimes the answer is sell as-is. The point of the data is that the decision should never be made without knowing the size of the discount being accepted.
