Detached-home sales in Troutdale spanned a wide range of sizes during 2024 and 2025. While sales ranged from under 1,000 square feet to more than 5,000 square feet, most buyers purchased homes within a much narrower range, with homes 1,400-1,499 SF the most dominant bracket.
The table below compares key home-size metrics across both years.

| Median Total SF | 1,727 | 1,614 | -113 SF |

Smaller detached homes sold on average in 2025 than in 2024. Average home size declined from 1,768 SF to 1,706 SF, while median size fell from 1,727 SF to 1,614 SF. At the same time, the largest detached-home sale increased from 2,992 SF to 5,100 SF, illustrating the presence of a small upper-end market.
The chart below shows where detached-home sales were concentrated by total square footage during 2024 and 2025.
Detached homes smaller than 1,200 SF saw relatively few transactions. The number of sales increased noticeably beginning in the 1,200-1,299 SF & 1,300-1,399 ranges and remained strong through much of the market’s mid-sized ranges, reaching a peak in the 1,400-1,499 SF range, which recorded 27 sales. Other notable concentrations occurred in the 1,500-1,599 SF range (25 sales), the 1,700-1,799 SF range (23 sales), and the 1,900-1,999 SF range (21 sales).
The final size band (≥2,800 SF) serves as a catch-all category for the market’s thin upper tail. Larger detached homes continued to sell throughout the study period, but transaction volume declined substantially beyond roughly 2,100 SF.
The table below summarizes each size band and includes average sales price, average living area, average year built, and average lot size.
