Columbia (WA) Investor Pulse Report (2025-Q4)

Landlord-owned properties constitute a significant 28.6% of the Single-Family Residential market in Columbia County, with a total of 476 properties under investor control.

The ownership structure is overwhelmingly dominated by individuals rather than corporations. Individual investors own 429 properties, accounting for 90.1% of the investor-owned portfolio, while companies own the remaining 59 properties (12.4%).

This individual dominance is also reflected in the entity count, where there are 501 individual landlords compared to only 35 company landlords, a ratio of more than 14 to 1.

Investor portfolios are primarily held without financing. A remarkable 85.3% of investor-owned homes (406 properties) are owned with cash, while only 14.7% (70 properties) are financed, suggesting a low-leverage, long-term holding strategy among local investors.

The portfolio is almost entirely dedicated to rentals, with 463 of the 476 properties (97.3%) classified as non-owner-occupied, underscoring the role of these investors as primary suppliers of single-family rental housing in the county.

In the most recent quarter, Q4 2025, landlords demonstrated a slight pricing advantage, acquiring properties at an average price of $238,704 compared to the traditional homeowner's average of $245,824. This represents a 2.9% discount, or $7,120 per property.

However, this pricing advantage is not consistent and shows extreme volatility on a quarterly basis. For example, in Q3 2025 landlords paid a significant 20.8% premium ($70,373), while in Q2 they secured a massive 47.8% discount ($134,229), suggesting that low transaction volumes can cause dramatic swings in average prices.

The data reveals a stark drop-off in purchasing activity, with landlords acquiring zero properties throughout all of 2024 and 2025. This indicates a significant slowdown or pause in investor acquisitions in the current market.

The sharpest contrast in pricing occurred in Q2 2025, where the landlord average price was just $146,664 against the homeowner average of $280,893. This highlights the potential for opportunistic purchasing in a market with low transaction counts.

Overall pricing trends show significant fluctuation, with the average landlord acquisition price moving from $170,656 in 2024 to a projected $317,832 for 2025, though this is based on very few transactions.

Investor activity represented a small fraction of the overall market in Q4 2025, with landlords purchasing 2 of the 21 total SFR properties sold, a market share of 9.5%.

The entirety of this purchasing activity was driven by the smallest investors. Mom-and-pop landlords (1-10 properties) accounted for 100% of the 2 properties acquired by investors.

Notably, all investor acquisitions were made by new entrants in the 'Single-property' tier. This suggests that recent activity is characterized by new landlords entering the market rather than existing ones expanding their portfolios.

There was a complete absence of activity from larger investors. Mid-size (11-1,000 properties) and institutional (1,000+ properties) landlords made zero purchases in Q4.

The data shows 4 entities were involved in the purchase of the 2 properties by single-property landlords, indicating that co-ownership was a factor in these new market entries.

The investor landscape in Columbia County is defined by the absolute dominance of small-scale landlords. 'Mom-and-pop' investors, those owning 1-10 properties, collectively control 99.6% of all investor-held SFRs.

Single-property landlords form the bedrock of the market, owning 309 properties. This tier alone accounts for 62.0% of the entire investor-owned housing stock, highlighting the fragmented and granular nature of ownership.

In stark contrast, institutional investors (1,000+ properties) have a virtually nonexistent presence, holding just a single property, which translates to a mere 0.2% market share.

Mid-size landlords are also exceptionally rare. The 11-20 property tier contains only 1 property (0.2%), reinforcing the pattern that the market is almost exclusively composed of very small operators.

The ownership distribution is heavily concentrated at the lowest end, with landlords owning 1-5 properties controlling a combined 93.8% of the investor portfolio (467 properties).

Individual investors are the primary owners across all portfolio sizes in Columbia County, preventing companies from achieving a majority stake in any tier.

The point of highest corporate concentration occurs in the 'Small landlord (6-10)' tier, where companies own 14 of the 29 properties, a substantial 48.3% share. However, individuals still maintain a slim majority with 15 properties (51.7%).

In the largest and most foundational tier of single-property landlords, individual ownership is at its most pronounced. Individuals own 295 of the 309 properties in this group, a commanding 93.4% share.

As portfolio sizes increase from one property, company ownership share gradually rises, moving from 6.6% in the single-property tier to 11.8% in the two-property tier, and 15.9% in the 3-5 property tier, before peaking at 48.3%.

This pattern indicates that while incorporation becomes a more common strategy for landlords as they grow, the Columbia County market remains fundamentally driven by individual, non-corporate ownership at every level.

Geographic analysis reveals that investor ownership in Columbia County is not evenly distributed but is instead highly concentrated in specific zip codes. The 99328 zip code is the epicenter of activity by volume, containing 352 investor-owned SFRs.

A stark contrast exists between the region with the most investor properties and the one with the highest ownership rate. While 99328 leads in count, its investor ownership rate is 23.8%.

The most heavily saturated market is Zip Code 99359, where investors own 109 properties, accounting for an overwhelming 87.2% of the area's entire SFR housing stock.

The top two zip codes by property count, 99328 and 99359, together account for 461 of the 476 total investor-owned properties in the county, representing 96.8% of the entire portfolio.

Other areas have far lower levels of investor penetration. For instance, Zip Code 99347 has a 20.0% investor ownership rate, and 99361 has a 12.5% rate, illustrating the hyper-local nature of investment strategies.

Historical transaction data clearly shows that landlords in Columbia County are in an accumulation phase, consistently buying more properties than they sell.

In 2025, landlords purchased 25 SFR properties while selling only 4, resulting in a strong buy-to-sell ratio of 6.25 and a net gain of 21 properties to their portfolios.

This trend holds true on a quarterly basis. In Q4 2025, landlords were net buyers with 4 purchases and 1 sale, and in Q3 they were even more active with 14 purchases versus 2 sales.

The pattern of net acquisition extends back through 2024, a year in which landlords bought 27 properties and sold just 5, for a net increase of 22 properties.

Institutional investors (1,000+ tier) were completely absent from the transaction market, reporting zero buys and zero sells across all timeframes, underscoring that all market dynamics are driven by smaller landlords.

Landlord participation in the Q4 2025 transaction market was limited, with investors accounting for 4 of the 34 total SFR transactions, a share of 11.8%.

All investor transaction activity was driven exclusively by the smallest market participants. The 'Single-property' tier was responsible for 100% of the 4 landlord-involved transactions.

These new market entrants paid an average purchase price of $238,704 for their properties in Q4.

There was no inter-landlord trading during the quarter, with 0% of landlord purchases coming from other landlords. This signifies that all new acquisitions were sourced from the broader market, likely from traditional homeowners.

The absence of transactions from any tier other than the smallest one highlights a market where portfolio expansion by existing landlords has paused, with new entrants being the only source of investor activity.
