Detached-home sales in Troutdale were heavily concentrated on modest suburban lots during 2024 and 2025. While site sizes ranged from 0.06 acres to 3.95 acres, most detached-home sales occurred on lots of approximately 0.15 acres and less than 0.30 acres.

The table below compares key lot-size metrics across both years.

Category	2024	2025	Change
Average Lot Size	0.2160	0.2121	-1.77%
Median Lot Size	0.1800	0.1700	-5.55%

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.

PAB Insights: When Were Troutdale’s Homes Built (2024-2025)?

Detached-home sales in Troutdale were heavily concentrated among homes built from the 1970s onward. During 2024-2025, 94.47% of all detached-home sales involved homes built between 1970 and 2009, with the largest concentrations occurring among homes built in the late 1970s and early 1990s.

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.

The table below compares key year-built metrics across both years.

Category	2024	2025	Change
Average Year Built	1990	1988	-2 Years
Median Year Built	1992	1990	-2 Years

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.

The table below summarizes each construction-era band and includes average sales price, home size, year built, and lot size.

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.

PAB Insights: Which Home Sizes Sold Most Often in Troutdale (2024-2025)?

Detached-home sales in Troutdale were highly concentrated, with 79.57% of all sales occurring between 1,200 SF and 2,099 SF during 2024-2025. Average home size declined by 62 SF, while median home size fell by 113 SF.

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.

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 table below summarizes each size band and includes average sales price, average living area, average year built, and average lot size.

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.

Troutdale’s detached-home market was highly concentrated between 1,200 SF and 2,099 SF.

PAB Insights: What Income Was Required to Buy a Home in Troutdale (2024-2025)?

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.

Metric	2024	2025	Change
Avg Required Income	$137,475	$131,873	-4.07%
Median Required Income	$134,148	$128,256	-4.39%
Affordable Sales	7	43	+36 homes
% Affordable	6.25%	34.96%	+28.71 pts

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.

Category	2024	2025	Change
Avg Principal & Interest Share	82.47%	82.05%	-0.42 pts
Avg Taxes Share	12.01%	12.17%	+0.16 pts
Avg HOA Share	0.21%	0.41%	+0.20 pts
Avg Insurance Share	5.31%	5.37%	+0.06 pts

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.

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.

Rates & slightly higher income tipped the scale.

PAB Insights: What Could Different Household Incomes Buy Among Troutdale’s Affordable Homes?

During 2024 and 2025, 50 detached homes in the City of Troutdale were classified as affordable, as measured by the Portland Appraisal Blog Affordability Index (PABAI). A household earning approximately $124,000 could have qualified for all of them.

During 2024 and 2025, detached homes accounted for 92.16% of all residential sales occurring within Troutdale city limits. As a result, most discussions about housing affordability in Troutdale are effectively discussions about the detached-home market.

During the two-year study period, 235 detached homes sold on the open market. Of those, 50 (21.28%) were classified as affordable under the Portland Appraisal Blog Affordability Index (PABAI). The majority of the affordable homes (43 of the 50) sold in 2025.

The required-income figures above describe the entire detached-home market, not just affordable homes. During the study period, the most expensive detached home that still qualified as affordable required approximately $123,916 of household income. That figure closely aligned with the applicable HUD MSA family income used during much of the period.

The following table is cumulative. For example, a household earning $115,000 could theoretically access all affordable detached homes requiring $115,000 or less in qualifying income. Likewise, a household earning $124,000 could access the entire inventory of detached homes meeting the affordability standard.

Household Income	# Affordable	Avg Price	Avg Total SF	Avg Acres	Avg Year
$100,000	4	$359,375	1,495	0.175	1956
$115,000	28	$410,250	1,425	0.162	1981
$124,000	50	$428,457	1,462	0.164	1984

One of the most interesting findings is that higher household income primarily expanded buyer choice rather than dramatically changing the type of home available. The number of attainable homes increased substantially as income increased, but the physical characteristics of those homes remained surprisingly similar.

Home size, lot size, and age varied less than many buyers might expect. Across all three tiers, the typical affordable detached home remained roughly 1,400 to 1,500 square feet on approximately 0.16 to 0.18 acres.

The more meaningful differences appeared in inventory count and property condition. The lowest-income tier included several fixer and distressed-sale opportunities, while the highest-income tier opened access to a much larger selection of well-maintained and updated homes. The affordable inventory was dominated by traditional suburban housing styles, particularly one-story ranch homes and split-level designs. Among the ten highest-priced affordable detached homes sold during the study period, only one was reported in below-average condition, with the remainder described as being in good, updated, or remodeled condition.

For Troutdale’s relatively uniform detached-home market, additional household income often translated into more options and better-condition homes rather than dramatically larger ones. Households near the $124,000 income tier not only gained access to the full affordable detached-home inventory, but also enjoyed a broader selection of turnkey homes requiring little or no immediate repair work.
