Sales activity was generally consistent between 2024 and 2025, although some months experienced noticeable year-over-year changes. April and May recorded increases of 4 and 5 sales, respectively, while June experienced the largest decline, falling by 5 sales. Despite these fluctuations, the overall seasonal pattern remained similar across both years.
The chart below displays detached-home sales by calendar month during the study period.

A clear seasonal pattern emerged. Sales activity increased during the spring months, with April through June accounting for 70 sales. Activity softened somewhat during July and August before strengthening again during the fall months. September through November accounted for 65 sales, nearly matching the spring selling season.
The table below summarizes monthly sales activity and includes average sales price, home size, year built, lot size, and affordable-home count.

Note: The Total/Avg row reports total sales and total affordable homes. All other columns represent averages for the study period.
How affordability is defined: The Portland Appraisal Blog Affordability Index (PABAI) was used to evaluate affordability during the study period. PABAI calculates the income needed to buy each home using its actual reported price, taxes, HOA dues, and an insurance estimate, financed at the Freddie Mac 30-year rate in effect at the time of sale. A home is considered affordable if the required income does not exceed the HUD median family income for the Portland-Vancouver-Hillsboro MSA in effect at the time of sale.
September recorded the highest number of sales with 26 transactions, followed closely by May with 25 sales and April with 24 sales. January was the slowest month, with 13 sales.
Average home size and construction year varied within a relatively narrow range throughout the year, while monthly average close prices showed somewhat greater variation. Average lot sizes were highest during August and September, although those months coincided with the sales of the 2.37-acre property sold in August and the 3.95-acre property sold in September, the two largest lots in the entire dataset. Those individual transactions had an outsized influence on the monthly lot-size averages.
Affordable-home activity was strongest during the fall months. September through November accounted for 22 affordable-home sales, including 8 affordable sales in October, the highest monthly total recorded during the study period. Extending the period through December increases the total to 27 of the 50 homes classified as affordable under PABAI.
This pattern coincided with generally lower mortgage rates during much of 2025 relative to 2024. Previous Troutdale studies also found that homes sold during 2025 tended to be somewhat smaller and less expensive than those sold during 2024, both of which contributed to improved affordability conditions.
Troutdale’s detached-home market exhibited two primary selling seasons during 2024-2025, with activity peaking during April through June and again during September through November. September recorded the highest number of sales, while affordable-home opportunities were most common during the fall months.
