Benton County

Benton County's numbers tell a clear story before you even run a full underwrite. At a median home price of $553,203 and median rent of $1,810, the gross rent-to-price ratio sits at 3.93%, which is well below the 7–8% threshold most cash-flow investors treat as a baseline for penciling. The modeled cap rate of 2.55% confirms what that ratio implies: this market prices in appreciation, not income. Running a standard leveraged scenario with 20% down ($110,641), a 6.85% rate, and estimated monthly expenses of $634, the cash-flow projection lands at negative $1,723 per month, a cash-on-cash return of -16.25%. That is not a rounding error or a pessimistic assumption; it is the arithmetic of a market where assets are priced for future value gains, not current yield. Year-over-year home price growth of 0.3% means even the appreciation thesis is quiet right now. The overall score of 39 out of 100, with a cash-flow score of 29 and an appreciation score of 53, reflects a market that is mediocre at both things simultaneously.

Given those figures, the honest answer is that Benton County fits a narrow investor profile. A pure cash-flow buyer should not be here: the negative carry is not a short-term disruption to manage through, it is the structural condition of this market at current prices and rates. An appreciation buyer could make a case anchored on long-term demand from a stable institutional tenant base, but with trailing home price growth at 0.3%, that thesis requires patience measured in years, not quarters. The sharpest fit might be a value-add operator who can force appreciation through renovation and reset rents meaningfully above the $1,810 median, but even then, the starting cap rate of 2.55% leaves almost no room for underwriting error. An affordability index of 21 out of 100 means the pool of potential renters who can comfortably carry local rents is constrained, which matters when projecting rent growth or lease-up timelines after a value-add project.

Benton County's economy is anchored by Oregon State University, a land-grant research institution in Corvallis that functions as the county's dominant employer. University towns tend to generate recession-resistant rental demand, particularly for one- and two-bedroom units, because enrollment and graduate research activity are relatively insulated from private-sector hiring cycles. That dynamic supports occupancy stability and is the primary reason the stability score (50) outperforms the cash-flow score by 21 points. Investors underwriting here are implicitly betting that OSU's workforce and student population will keep a floor under rental demand even if the broader Oregon economy softens. That is a credible thesis, but it also means the renter base skews toward academics, staff, and students, groups with specific unit-size preferences and turnover patterns worth modeling explicitly.

On carry costs, the combined monthly tax and insurance figure of $535 is already baked into the modeled expense load of $634. Oregon's state-average effective property tax rate of 0.97% carries a "normal" flag, meaning it is not a material tailwind or headwind relative to national norms, though the note accompanying this data is worth respecting: that rate is a state-average estimate from Tax Foundation 2024, and actual Benton County or township rates may differ. At a $553,203 purchase price, the annual tax estimate of $5,366 is real money, and investors should pull the county assessor's actual rate for any specific parcel before closing. The insurance estimate of $1,051 annually is relatively modest, consistent with Oregon's lower catastrophic weather exposure compared to Gulf Coast or tornado-belt markets.

The risk picture in Benton County is concentrated rather than diversified. A county of 95,615 people with a dominant single employer means that any material change to OSU's enrollment policy, state funding, or operational footprint would ripple directly into rental demand and potentially resale liquidity. Oregon also operates under landlord-tenant statutes that favor tenant protections, including statewide rent stabilization rules that apply to older housing stock; investors acquiring pre-2015 units need to verify applicable caps before projecting rent resets. The combination of single-employer concentration, below-median affordability at a score of 21, and a regulatory environment that limits rent flexibility adds layers of downside risk that the 2.55% cap rate does not compensate for.

Against its neighbors, Benton does not stand out favorably. Tillamook County posts a rent-to-price ratio of 4.64% at a median price of $503,130, a better yield profile at a lower entry cost and an overall score of 40. Washington County, at $556,184 median price, achieves a 4.08% ratio and an overall score of 41, suggesting marginally better income dynamics with comparable appreciation exposure. Multnomah County at $493,151 and a 4.10% ratio offers a larger, more liquid market at lower basis. Benton ranks 30th out of 36 Oregon counties in the dataset, which means most of the state offers a more investable setup. An investor should choose Benton over these neighbors specifically when they are targeting the OSU institutional demand corridor, have high conviction on long-term Corvallis appreciation, and can tolerate sustained negative cash flow from a position of financial strength. For anyone who needs the property to carry itself, Tillamook or Washington County deserves the allocation first.
