City of Troutdale Lot Size Comparisons Single-Family Detached Residential | 2024 vs. 2025 Data: RMLS |PortlandAppraisalBlog.com
Note: Lot sizes are reported by listing agents in RMLS and may be approximate. These figures are best used to identify broad market patterns rather than determine precise site areas.
The typical detached-home lot sold in 2025 was slightly smaller than in 2024. Average lot size declined from 0.2160 acres to 0.2121 acres, while median lot size declined from 0.1800 acres to 0.1700 acres. Converted to approximate square-foot equivalents, average lot sizes were approximately 9,200-9,400 square feet, while median lot sizes ranged from roughly 7,400-7,800 square feet.
The histogram below shows where detached-home sales were concentrated by lot size during 2024 and 2025.
Lot sizes were highly concentrated within a relatively narrow range. The largest concentration occurred between 0.150 and 0.174 acres (63 sales), followed by 0.175-0.199 acres (39 sales), 0.200-0.224 acres (29 sales), and 0.225-0.249 acres (27 sales). Together, these four adjacent ranges accounted for 158 of 235 sales.
Relatively few detached-home sales occurred on large lots. Sales activity declined steadily beyond 0.25 acres, while acreage properties represented only a small portion of the market.
The table below summarizes each lot-size band and includes the number of sales as well as average sales price, home size, construction era, and lot size.

City of Troutdale Home Sales by Lot-Size Band Single-Family Detached Residential | 2024 & 2025 Data: RMLS |PortlandAppraisalBlog.com
The market was highly concentrated. Lots between 0.050 and 0.299 acres accounted for 224 of 235 sales, or 95.32% of all detached-home transactions during the study period.
Sale prices generally increased as lot sizes increased, although transaction counts became sparse beyond approximately 0.30 acres. The largest-lot cohort averaged more than $700,000, 2,502 square feet, and 1.36 acres, but included only seven sales.
Smaller lots also tended to be associated with newer development. The smallest detached-home lots in the study averaged just 0.064 acres and were built around 2006, while larger-lot homes generally reflected older construction periods. This pattern aligns with a common subdivision-development trend in which newer homes are built on increasingly smaller sites.
Troutdale’s detached-home market was overwhelmingly concentrated on lots between approximately 0.05 and less than 0.30 acres.

Detached-home sales in Troutdale spanned construction dates from the late 1800s to the 2020s during 2024 and 2025. Although Troutdale was incorporated in 1907, the overwhelming majority of detached homes sold during the study period were built from the 1970s onward.

City of Troutdale Year Built Comparisons Single-Family Detached Residential | 2024 vs. 2025 Data: RMLS |PortlandAppraisalBlog.com
The typical detached home sold in 2025 was slightly older than in 2024. Average year built declined from 1990 to 1988, while median year built declined from 1992 to 1990. Across the two-year study period, the oldest home sold was built in 1893, while the newest was built in 2022.
The chart below shows where detached-home sales were concentrated by construction era during 2024 and 2025.
Detached-home sales involving homes built before 1970 were relatively uncommon. The number of sales increased sharply beginning in the 1970s and remained elevated through much of the late-20th-century and early-21st-century housing stock.
The largest concentrations occurred among homes built in 1975-1979 (48 sales), 1990-1994 (47 sales), 1995-1999 (39 sales), and 2005-2009 (28 sales). Rather than reflecting steady construction over time, the distribution suggests Troutdale’s detached-housing stock developed through a series of major building cycles.
Construction activity was noticeably lighter during the 2010s, and the newest home sold during the study period was built in 2022.

City of Troutdale Home Sales by Year-Built Band Single-Family Detached Residential | 2024 & 2025 Data: RMLS |PortlandAppraisalBlog.com
The market was highly concentrated. Homes built between 1970 and 2009 accounted for 222 of 235 sales, or 94.47% of all detached-home transactions during the study period.
Within these construction eras, average home sizes generally increased over time. Homes built during the 1970s averaged approximately 1,600-1,700 square feet, while homes built after 2000 commonly exceeded 2,000 square feet.
Lot sizes generally moved in the opposite direction. As newer subdivisions were developed, homes tended to become larger while the average site size became smaller, a common pattern as builders sought to maximize the number of homes within a subdivision.
Troutdale’s sales over the study period with an average year built of 1989 reflect the center of several major development waves rather than a single dominant construction period. The strongest concentrations occurred in the late 1970s and again from the early 1990s through the 2000s.
Troutdale’s detached-home market was overwhelmingly concentrated in homes built between 1970 and 2009.

City of Troutdale Total Square Footage Comparisons Single-Family Detached Residential | 2024 vs. 2025 Data: RMLS |PortlandAppraisalBlog.com
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 market was highly concentrated. Homes between 1,200 SF and 2,099 SF accounted for 187 of 235 sales, or 79.57% of all detached-home transactions during the study period.
Within this range, average sales price increased from approximately $457,000 to a little over $530,000 as home size increased. Most homes in the market’s most active size ranges were built during the 1980s and 1990s, reflecting the era that helped define much of Troutdale’s detached-housing stock.
Despite substantial differences in living area, average lot sizes remained relatively consistent throughout much of the market’s core size ranges.

Average required income for Troutdale detached homes declined from $137,475 in 2024 to $131,873 in 2025. While required incomes fell only modestly, affordable detached-home sales increased dramatically as many homes sat near the affordability threshold. Rates tipped the scale.

The amount of income required to purchase a detached home in Troutdale declined modestly between 2024 and 2025. While average and median required incomes fell by roughly 4%, the share of detached-home sales classified as affordable under the Portland Appraisal Blog Affordability Index (PABAI) increased dramatically.
The table below compares key required-income metrics across both years.

Detached-home affordability overview, Troutdale city limits. Affordable homes determined using PABAI. Single-Family Detached Residential | 2024 vs. 2025 Data: RMLS |PortlandAppraisalBlog.com
How “affordable” is defined: PABAI calculates the income needed to buy each home using its actual reported price, taxes, HOA dues, and insurance estimate, financed at the Freddie Mac 30-year rate in effect at the time of sale. A home counts as affordable if that required income is at or below the HUD median family income for the Portland-Vancouver-Hillsboro MSA in effect at the time.
At first glance, the affordability gains appear out of proportion to the decline in required incomes. Average required income fell just 4.07%, yet affordable detached-home sales increased from 7 to 43.
Part of the explanation can be found in how ownership costs were allocated.

Average share of housing payments attributable to principal & interest, property taxes, HOA dues, and insurance as modeled under the PABAI framework. Shares are averaged across all detached sales; sales without HOA dues count as 0% HOA. Single-Family Detached Residential | 2024 vs. 2025 Data: RMLS |PortlandAppraisalBlog.com
Mortgage principal and interest accounted for roughly 82% of the typical modeled housing payment in both years. While the P&I share declined by only 0.42 percentage points between 2024 and 2025, that small change proved meaningful because detached-home sales were heavily concentrated near the affordability threshold. In a market sitting at the boundary of affordability, even modest improvements in financing costs can move a significant number of homes from unaffordable to affordable.
Taxes and insurance remained relatively stable. HOA dues represented a larger share of modeled ownership costs in 2025, although part of that increase can be attributed to a greater number of HOA-governed homes selling in 2025 (35) than in 2024 (24).
The table above illustrates why mortgage rates matter. When more than four-fifths of a typical housing payment is attributable to financing costs, even modest improvements in mortgage financing conditions can materially affect affordability.
The chart below combines 2024 and 2025 detached-home sales to show where required incomes were concentrated.
Most detached-home sales required between roughly $115,000 and $149,999 of annual household income. The green bars represent homes that met the PABAI affordability standard in effect at the time of sale.
The first four income bands were naturally affordable because they generally fell below the applicable HUD median family income thresholds throughout the study period. Additional affordable sales appeared in the $115,000-$119,999 and $120,000-$124,999 income bands, reflecting changes in affordability thresholds and financing conditions over time.
The table below summarizes the distribution and includes the percentage of sales in each band, making it easier to evaluate where the market was concentrated.

Detached-home sales by required income band (2024-2025), including the share of sales and number classified as affordable under PABAI. Lower bound inclusive. Single-Family Detached Residential | 2024 & 2025 Data: RMLS |PortlandAppraisalBlog.com
Nearly three-quarters (73.62%) of all detached-home sales required between $115,000 to $149,999 of annual household income. The single largest income band was $130,000 to $134,999, accounting for 13.19% of all sales.
The market was not dominated by homes requiring substantially more income than the affordability threshold. Instead, many sales clustered immediately around it. As mortgage rates modestly improved during much of the 2025 selling season, required incomes fell enough to bring more homes into the affordability zone. Affordability was also buoyed by a rising HUD median family income for the Portland-Vancouver-Hillsboro MSA: $114,400 in 2024, rising to $124,100 by April 2025 and holding there through year-end.

Troutdale’s 2025 housing market generated more than $64 million in residential sales, with detached homes accounting for over 93% of all transactions. Affordability rose sharply; 35% of detached sales were affordable, up from 6%. This was due to softer prices and more favorable mortgage interest rates during peak selling season in 2025 compared with 2024.

January 2025 – December 2025 (132 total residential sales). Data: RMLS | PortlandAppraisalBlog.com
Detached homes accounted for the overwhelming majority of residential sales activity in Troutdale during 2025. Total residential dollar volume across all tracked housing segments reached approximately $64.2 million, with detached homes representing more than 93% of all sales and nearly 95% of total dollar volume. Attached homes and condominiums represented a relatively small share of the market, while no manufactured homes on owned land sold during the year. The following sections examine each segment in greater detail.
Detached Homes
Detached homes represent the largest and most active residential housing segment in Troutdale. Because detached properties accounted for more than 9 out of 10 sales during 2025, this segment provides the clearest view of local market conditions.
Detached Homes Market Statistics
The following table compares detached-home sales activity occurring within Troutdale city limits during 2024 and 2025. Metrics include sales volume, pricing, property characteristics, marketing times, and affordability.

Detached-home sales activity increased during 2025, with total sales rising from 112 to 123 and total dollar volume increasing 6.51% to approximately $60.9 million. Despite stronger sales activity, both average and median sales price declined modestly, while average days on market increased just 3 days, from 39 to 42 days. Buyers also gained slightly more negotiating leverage, with the average sale-to-original-list-price ratio declining from 99.27% to 98.09%.
The typical detached home sold during 2025 was somewhat smaller and slightly older than in 2024, while average price per square foot increased modestly. No new detached-home construction sales were recorded in either year, reinforcing Troutdale’s role as a largely resale-driven housing market. HOA participation remained a minority characteristic of the detached market, though the share of detached-home sales reporting HOA dues increased from approximately 21% in 2024 to 29% in 2025.
Detached Homes Sales by Price Range
The following table summarizes detached-home sales occurring within Troutdale city limits during 2025 by price range. In addition to sales volume, the table highlights the typical size and age of homes sold within each price band.
Troutdale’s detached-home market was concentrated in the middle price ranges during 2025. More than 89% of detached-home sales occurred between $400,000 and $599,999, with the $400,000-$499,999 range alone accounting for 71 of 123 sales. As sale prices increased, average home size generally increased as well, from approximately 1,500 square feet in the $400,000-$499,999 range to more than 3,200 square feet in the $700,000+ ranges.
While most sales occurred in homes built during the 1980s and 1990s, the two highest-priced detached-home sales were very different properties. One involved a nearly four-acre mixed-use development site along the Sandy River with an older home contributing little to overall value, while the other was a large historic residence with more than 5,000 square feet of living area and an accessory dwelling unit. These sales illustrate how Troutdale’s highest-priced properties can derive value from factors such as land, development potential, size, and unique property characteristics rather than age alone.
Detached Homes Affordability
The following table summarizes detached-home affordability in Troutdale during 2024 and 2025 using PABAI. In addition to the number and percentage of affordable sales, the table reports the highest affordable sale, the average sales price of affordable homes, and the average household income required to purchase those homes under prevailing market conditions at the time of sale.

Affordable sales are determined using the Portland Appraisal Blog Affordability Index (PABAI), which evaluates each detached-home sale using prevailing mortgage rates, household income assumptions, taxes, insurance, and financing costs at the time of sale.
Detached-home affordability improved substantially during 2025. The number of affordable detached-home sales increased from 7 to 43, while the share of affordable sales increased from 6.25% to 34.96% of the market. The highest affordable detached-home sale increased from $445,000 in 2024 to $474,900 in 2025.
As shown above, mortgage rates were generally higher throughout much of 2024 than 2025. Combined with modest declines in detached-home prices, lower financing costs expanded the number of homes meeting the affordability standard even though the highest affordable detached-home sale changed very little.
The average affordable detached home sold for $431,612 during 2025 and required an estimated household income of approximately $114,232. While affordability remained far from universal, Troutdale offered substantially more attainable detached-home ownership opportunities in 2025 than in the prior year.
Attached Homes
Attached homes represent a small but distinct segment of Troutdale’s housing market. While sales activity is limited compared with detached homes, attached housing can provide an ownership alternative for buyers seeking lower-maintenance living or a smaller land component.
Attached Homes Market Statistics
The following table compares attached-home sales activity occurring within Troutdale city limits during 2024 and 2025. Due to the limited number of sales, the results are best viewed as descriptive measures of market activity rather than indicators of broader market trends.

Attached-home sales represented a small portion of Troutdale’s residential market in both years, with only seven sales recorded during 2025. Despite the limited number of transactions, attached homes consistently contributed approximately $2.65 million in annual residential dollar volume during both 2024 and 2025.
Pricing measures, including average sales price, price per square foot, and sale-to-list-price ratio, were all lower in 2025 than in 2024. Because the attached-home market consists of a very small number of transactions, year-to-year changes are often skewed by compositional differences among the sales.

Affordable sales are determined using the Portland Appraisal Blog Affordability Index (PABAI), which evaluates each attached-home sale using prevailing mortgage rates, household income assumptions, taxes, insurance, and financing costs at the time of sale.
Attached homes remained one of Troutdale’s most affordable ownership options during both years analyzed. Six of seven attached-home sales met the PABAI affordability standard during 2025, compared with four of six sales during 2024. The average required household income fell from approximately $111,000 to $104,000; largely due to lower average sales prices in 2025 compared to the previous year.
Because the attached-home market consists of only a handful of transactions each year, affordability results should be interpreted cautiously. Nevertheless, the segment consistently provided ownership opportunities at lower price points than the detached-home market, with a large majority of sales meeting the affordability standard in both years.
Condominiums
Condominiums represent a very small segment of Troutdale’s residential market. Like attached homes, due to the limited number of sales, the results are best viewed as descriptive measures of market activity rather than indicators of broader market trends.

Note: All metrics use the full dataset for each year (including HOA dues). Condominium Residential | 2024 & 2025 Data: RMLS | PortlandAppraisalBlog.com
Condominium sales activity remained limited during both years, with only five sales recorded in 2024 and two sales recorded in 2025. While Troutdale contains several condominium communities, recent sales activity was concentrated in a small number of developments. Most of the condominium sales occurring during the period analyzed were located within the Edgefield Meadows community, a townhome-style condominium development.
Pricing remained relatively stable despite the limited number of transactions. Average price per square foot changed very little between years. All condominium sales reported HOA dues, with average monthly dues increasing from approximately $358 to $415. Because the condominium market consists of only a handful of transactions each year, changes in individual metrics strongly reflect the mix of unit sales.

Affordable sales are determined using the Portland Appraisal Blog Affordability Index (PABAI), which evaluates each condominium sale using prevailing mortgage rates, household income assumptions, taxes, insurance, and financing costs at the time of sale.
Condominium affordability remained strong during both years analyzed. Four of five condominium sales met the PABAI affordability standard during 2024, while both condominium sales recorded during 2025 qualified as affordable. Average affordable sales price remained in the mid-$300,000 range, while the average required household income remained relatively stable near $106,000 to $108,000.
Because condominium activity in Troutdale is limited, affordability results are heavily influenced by the specific units that sell during a given year. Nevertheless, the available data indicate that condominiums remained among the city’s more attainable ownership options during both years analyzed.

Key Takeaways
Troutdale’s housing market is, for practical purposes, a detached-home market. Detached homes accounted for the overwhelming majority of residential sales activity during 2025 and remain the property type that most clearly defines local housing conditions.
The city’s housing stock is primarily composed of resale housing rather than new homes. No new construction detached-home sales were recorded during either 2024 or 2025. Among detached-home sales occurring during the two-year period, construction dates ranged from 1893 to 2022, with the average home built in 1989.
While attached homes and condominiums provide alternative ownership opportunities, both segments remain relatively small and generate limited annual transaction volume compared with detached housing. For buyers looking to take advantage of their comparatively lower prices, such units do not come on the market very often and may require patience.
For buyers seeking a balance between affordability, access to the Portland Region, and proximity to outdoor recreation, Troutdale remains a community worth considering. Located at the gateway to the Columbia River Gorge, the city offers a housing market that remains more attainable than many higher-priced areas within the metropolitan region.
