Overview
Where things stand
Who we are
Foundry Realty
Three things guide every file we work: staying personal through a process that can feel anything but, being a source you can trust when the numbers get complicated, and letting data, not guesswork, guide the decisions that matter most.
This analysis is built the same way every recommendation is: from verified sales data, not assumptions.

03 · The Subject
18 Uptown Dr, Suite 217
Corner unit, Riverwalk Condos, Markham
Six months on market, three relistings, no sale. Strong evidence the ceiling sits below $580,000.
04 · Sold Comparables
Comparable sales
Adjusted for floor level, parking, locker, and time since sale
| Unit | Sold | Price | Sqft | Floor adj | Pkg / lkr | Date adj | Adj $/sqft |
|---|---|---|---|---|---|---|---|
| 18 Uptown 1707 | Jun 23/26 | $542,800 | 674 | −$14,000 | −$35,000 | None | $732.64 |
| 18 Uptown 321 | Oct 20/25 | $565,000 | 671 | −$3,000 | −$35,000 | −3.5% | $758.06 |
| 1 Uptown 603 | Apr 10/26 | $548,000 | 730 | −$5,000 | −$35,000 | +1.2% | $704.03 |
| 1 Uptown 509 | Feb 9/26 | $475,000 | 606 | −$4,000 | −$35,000 | +5.3% | $757.39 |
1707 and 321 are in your building. 603 and 509 are in the tower next door at 1 Uptown Dr, a similar-vintage sister building with a comparable but not identical amenity set. Date adjustments are drawn from Markham condo apartment price data, which bottomed in February 2026 and has been recovering since.
05 · The Number
Market value range
The full comparable range runs $545,000–$585,000. Same-building sales alone support the upper half of that, $570,000–$585,000, but 217's square footage is builder-sourced and larger than the MPAC-verified figures for comparable units in your own building, worth flagging before anchoring at the top end. $560,000–$570,000 balances the two.
06 · Active Listings
What's competing for the same buyer
Nine active 1-bed and 1+den units across both towers, ranked by $/sqft
07 · Market Trend
Where the market's been
Markham condo apartment median price, last 9 months
Chart scale starts at $500K to show the shape of the trend clearly.
Prices bottomed around February 2026 and have been recovering since. They're still down roughly 3.5% from a year ago, but the direction has turned in your favour over the last four months.
08 · Scenario Comparison
Sell now, wait a year, or hold three?
Every path below ends with a sale. Adjust the assumptions live to see how the 3-year outcome shifts.
Market
Mortgage
Rapid biweekly, 26 payments/yr, monthly-equivalent –/mo. Term ends Aug 1, 2027.
Variable-rate penalties are typically a flat 3 months' interest, unaffected by time left on the term. Set each independently.
Taxes
50% inclusion rate under current law. The home sale itself is never taxed. Principal residence exemption applies in every scenario.
Starting numbers & sale costs
Fixed facts, not adjustable: bought summer 2022, 5-year variable term ending Aug 1, 2027. Maintenance ($580.10/mo) and property tax ($213.41/mo) are held constant across all scenarios.
Net worth at the 3-year mark
Sell now
Rent at today's price, invest the proceeds for 3 years
Wait 1 year
Sell once the mortgage term ends, then rent + invest for 2 years
Hold 3 years
Keep the mortgage, sell at the end of year 3
This is a planning tool, not financial or tax advice. It models one path through many uncertain variables: condo prices, market returns, mortgage rates, and tax rules can all move differently than assumed here. Confirm mortgage penalty, commission, and tax specifics with your lender, brokerage, and accountant before making a decision.
