Lake County, Montana Eviction Risk: Very Low

Lake County, Montana eviction laws posts a county-wide average eviction-risk score of 2.3/10 (Low), placing it in the middle third of all 56 Montana counties. Nineteen counties in the state carry higher risk, and 36 are more landlord-friendly, so investors should treat this as a market with manageable but real exposure rather than a clear outlier in either direction. Across the county's 26 cities and communities, that average reflects a genuinely diverse mix of conditions, with scores spanning a meaningful range from 1.6 to 2.6 out of 10.

For landlords considering Lake County, the fundamentals tell a measured story. The average rent sits at $914 per month, and the average rent burden of 28.8% of income suggests tenants are not severely stretched by housing costs, which tends to support on-time payment rates. The renter share of 35.6% of households indicates a moderately sized rental pool. None of these figures scream crisis, but a poverty rate of 20.9% is a meaningful variable to factor into tenant screening and reserve planning.

The cities inside Lake County

Risk is genuinely hyper-local here. At the top of the range, Arlee and Old Agency both score 2.6/10, while Arlee (population 812) sits at the county ceiling. Polson, the county's largest city at 5,428 residents, comes in at 2.5/10, and Charlo matches that figure. Finley Point and Dixon each register 2.4/10. Landlords operating in these communities face the most concentrated set of risk factors in the county, though all remain in the Low tier on an absolute basis.

On the other end of the spectrum, St. Ignatius scores 1.6/10, the lowest in the county among the cities in DATA, and Lindisfarne comes in at 1.8/10. Ronan (population 2,001) and Pablo (population 1,632) both sit at 2.3/10, matching the county average. The distance between the softest and sharpest local markets, a full one-point spread, is wide enough that underwriting decisions should be made at the city level, not the county level.

State-level laws that apply here

Every Lake County landlord operates under Montana state law, specifically the Residential Landlord and Tenant Act (MCA § 70-24). Notice requirements are relatively tight: non-payment of rent and lease violations each require only a 3-day notice to cure or quit, while a no-cause termination at end of term requires 30 days. Montana does not require just cause for non-renewal, and state law preempts any local rent-control ordinance, meaning there is no rent cap formula to navigate anywhere in the county. Landlords must give tenants 24 hours advance notice before entry. For a full walkthrough of the eviction process timeline, the Montana eviction process guide covers uncontested cases, which run 21 to 45 days, through contested ones that can reach 45 to 120 days.

On the cost side, court filing fees run $90 to $170, sheriff lockout fees add $40 to $125, and attorney fees, if you retain counsel, range from $500 to $2,500. The Montana eviction costs guide details how these components add up across different case types. Those numbers are not trivial for a smaller single-family portfolio, which makes thorough upfront screening and lease documentation essential.

With a poverty rate of 20.9% and a renter share of 35.6%, Lake County presents a rental market where income volatility is a real underwriting consideration; the city-level score grid above shows exactly where that risk is most and least concentrated across the county's 26 communities.
