Grantham, St. Catharines - September 2026 Real Estate Report

Grantham Real Estate Right Now: Solid Ground, But Watch the Numbers

If you own a home in Grantham and you haven't checked your property value lately, this is your nudge. The market here isn't crashing, it isn't exploding - it's doing something more interesting. It's showing us exactly where the real opportunities are, and they depend a lot on what type of property you own.

The Vibe: Houses vs. Condos - Two Very Different Stories

Let's be straight with each other. Houses and condos in Grantham are moving in opposite directions right now, and that matters for what you do next.

On the house side, we're seeing a slight cooldown. The average HonestDoor Price sits at $645,654, down a small 0.37% from last period. The predicted market value is $648,058, and that number is drifting down from the 3-month moving average of $657,575. A -1.05% recent price change confirms houses are taking a breather. That said, when a house does sell, it moves fast - we're talking an average of just 6 days on market, which ranks 1st out of 7 comparable neighbourhoods in St. Catharines. That's the fastest in the city. The one house that sold recently went for $730,000, and the buyer paid 99.32% of list price. Sellers are getting close to what they're asking, but buyers do have a tiny bit of room to negotiate.

• Average HonestDoor Price (Houses): $645,654
• Recent price change: -0.37%
• Average sale price: $730,000
• Price per square foot: $660
• Average days on market: 6
• Sale-to-list ratio: 99.32%
• Rental estimate: $3,085/month
• Rental yield: 5.35%
• Growth rank: 9 out of 14 in St. Catharines
• Days-on-market rank: 1 out of 7 (fastest)
• Price rank: 2 out of 7 (above average)

Condos are a different conversation entirely. We're actually seeing momentum here. The average HonestDoor Price for condos is $393,911, up 1.43% from last period. The predicted market value of $388,370 is climbing above the 3-month moving average of $384,941, and the recent value change of +2.13% puts Grantham condos at 4th out of 14 neighbourhoods in St. Catharines for growth. That's above average. If you own a condo here, your asset is quietly gaining ground.

• Average HonestDoor Price (Condos): $393,911
• Recent price change: +1.43%
• Predicted market value: $388,370
• 3-month moving average: $384,941
• Rental estimate: $2,037/month
• Rental yield: 4.04%
• Growth rank: 4 out of 14 in St. Catharines (above average)

The Secret Sauce: Your HonestDoor Price Is the Number That Actually Matters

Here's the thing about your city tax assessment - it's a snapshot from the past. It doesn't know what happened in your neighbourhood last month. It doesn't adjust for the fact that Grantham houses are selling in 6 days, or that condo values just ticked up 2.13%.

The HonestDoor Price is updated in real time. It pulls from actual market activity, not a government spreadsheet that gets refreshed every few years. Right now, the HonestDoor Price for houses in Grantham is $645,654. For condos, it's $393,911. Those are the numbers a buyer or their agent is going to be working from - not your assessment notice.

If you're a house owner, the HonestDoor Price is telling you values have nudged down slightly. If you're a condo owner, it's telling you the opposite. Either way, knowing your real number today puts you in control of the conversation, not playing catch-up.

The "So What?" - Thinking About Selling This Summer?

If you own a house in Grantham and you're thinking about listing this summer, the timing argument is actually pretty strong - but for a specific reason. Houses here are selling in 6 days on average. That's the fastest pace in St. Catharines. Buyers are still showing up and paying 99.32% of list price. The market is stable, not panicked. You're not going to get a bidding war frenzy, but you're also not going to sit on the market for months.

The catch is pricing. With values down slightly and the predicted price sitting below the 3-month average, overpricing a house right now is a real risk. List sharp, and you'll move it fast. List high hoping for a miracle, and you'll watch that 6-day average become your enemy.

If you own a condo and you're on the fence, the data says wait and watch. Values are climbing, the growth rank is above average for the city, and the rental yield of 4.04% means holding it as an income property is a legitimate option while you decide. Lakeport condos are averaging $545,597 - well above Grantham's $393,911 - so there's a ceiling to watch, but we're not there yet.

Bottom line: Grantham is not a neighbourhood you need to panic about. Houses are steady with fast sales, condos are quietly building value. Check your HonestDoor Price, know your real number, and make a move based on facts - not a tax notice from two years ago.
