Updated 2026 · Based on median market data for Stillwater, OK
The median monthly rent in Stillwater, OK is $1,320, translating to $15,840 in annual gross rental income per unit. The rent-to-price ratio is 0.56% — well below the 1% rule, making pure cash flow investing challenging at median prices and requiring investors to target below-median purchases or value-add strategies. For context, a 0.56% rent-to-price ratio means that for every $100,000 invested in property, you collect approximately $562/mo in gross rent. The gross rent multiplier of 14.8x means it takes 14.8 years of gross rent to equal the purchase price — a moderate ratio typical of balanced markets.
Renters in Stillwater spend approximately 28% of the local median household income ($56,350) on rent. This is within the healthy 25-30% range, indicating rent is affordable relative to local incomes. There may be room for moderate rent increases, especially for updated or well-located units. The 30% affordability ceiling suggests maximum supportable rent of approximately $1,409/mo — that is $89/mo above current median rent.
The vacancy rate in Stillwater is 5.8%. This is a healthy vacancy rate that indicates balanced supply and demand. You should be able to find quality tenants without extended vacancies, though expect normal turnover periods of 2-4 weeks between tenants. Budget for one month of vacancy per year in your underwriting to be conservative. Population growth of 0.9% annually provides stable demand.
Stillwater's GRM (price divided by annual rent) is 14.8x. A GRM between 12-16x is moderate and typical of balanced markets. Deals can work but you need to keep expenses controlled and buy at or below the median to achieve strong returns. For comparison, the national average GRM for investment-grade rentals is approximately 13-15x. To beat Stillwater's median GRM, target properties where you can achieve rents above $1,320 through renovations, better marketing, or targeting underserved tenant segments — or buy at a discount to the $235,000 median price. Every point lower on GRM translates to roughly 0.5-0.8% improvement in your cap rate.
At the median rent of $1,320/mo, a single-family rental in Stillwater generates approximately $15,840 in gross annual income. After accounting for 5.8% vacancy ($919 lost), property taxes of $2,068, insurance (~$940), and maintenance (~$940), the estimated NOI is $10,973 per year, or $914/mo. Adding an 8% management fee ($1,267/yr) reduces investor cash flow further. Before debt service, you are looking at approximately $9,706/yr in landlord net income. Whether this is attractive depends on your total capital invested — at a $47,000 down payment, the unlevered yield on equity from NOI alone is 23.3%.
Rent growth in Stillwater is driven by the interplay of population growth (0.9%), income growth, and housing supply constraints. Moderate population growth of 0.9% supports steady rent increases of approximately 2.5% per year. That trajectory takes today's $1,320/mo to $1,421 in 3 years and $1,493 in 5 years. The affordability headroom of $89/mo between current rents and the 30% income threshold offers some room for increases, though landlords should be strategic about timing and magnitude.
With a median income of $56,350 and affordable home prices ($235,000), many tenants in Stillwater are working families and individuals who could buy but choose to rent — or are saving for a down payment. This creates a reliable tenant base that values stability and tends to stay longer, reducing turnover costs. In a smaller market of 50,000 residents, word-of-mouth and local listing platforms may be more effective than national sites for finding tenants.
Stillwater is a smaller market where professional PM options may be limited. Fees can run 10-12% of rent, and the quality of available managers varies widely. At $1,320/mo, management costs roughly $145/mo. Self-management makes sense if you are local, have fewer than 5 units, and the rent level justifies your time — at $1,320/mo, self-management of a small portfolio saves meaningful dollars but professional management becomes economical at 3-4 units.
