Updated 2026 · Based on median market data for Brookings, SD
The median monthly rent in Brookings, SD is $1,450, translating to $17,400 in annual gross rental income per unit. The rent-to-price ratio is 0.47% — 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 0.47% rent-to-price ratio means that for every $100,000 invested in property, you collect approximately $468/mo in gross rent. The gross rent multiplier of 17.8x means it takes 17.8 years of gross rent to equal the purchase price — a high ratio that reflects price appreciation outpacing rent growth.
Renters in Brookings spend approximately 31% of the local median household income ($56,400) on rent. This exceeds the standard 30% affordability threshold, suggesting rent growth may face resistance — but it also means a large portion of the population finds buying even more out of reach, supporting deep rental demand. Landlords should be cautious about aggressive rent increases and focus instead on tenant retention to minimize costly turnover.
The vacancy rate in Brookings is 4.9%. This is extremely tight — expect strong tenant demand, quick lease-ups, and leverage to set favorable lease terms. In markets this tight, landlords often see multiple applications per listing and can be highly selective on credit scores and income verification. You can also justify annual rent increases of 3-5% without significant pushback. Population growth of 1.4% annually is actively adding rental demand, creating a tailwind for landlords.
Brookings's GRM (price divided by annual rent) is 17.8x. A GRM above 16x means the property is expensive relative to its income. Investors here are typically betting on appreciation rather than current cash flow, which adds risk if the appreciation thesis does not materialize. For comparison, the national average GRM for investment-grade rentals is approximately 13-15x. To beat Brookings's median GRM, target properties where you can achieve rents above $1,450 through renovations, better marketing, or targeting underserved tenant segments — or buy at a discount to the $310,000 median price. Every point lower on GRM translates to roughly 0.5-0.8% improvement in your cap rate.
At the median rent of $1,450/mo, a single-family rental in Brookings generates approximately $17,400 in gross annual income. After accounting for 4.9% vacancy ($853 lost), property taxes of $3,720, insurance (~$1,240), and maintenance (~$1,240), the estimated NOI is $10,347 per year, or $862/mo. Adding an 8% management fee ($1,392/yr) reduces investor cash flow further. Before debt service, you are looking at approximately $8,955/yr in landlord net income. Whether this is attractive depends on your total capital invested — at a $62,000 down payment, the unlevered yield on equity from NOI alone is 16.7%.
Rent growth in Brookings is driven by the interplay of population growth (1.4%), income growth, and housing supply constraints. Moderate population growth of 1.4% supports steady rent increases of approximately 2.5% per year. That trajectory takes today's $1,450/mo to $1,561 in 3 years and $1,641 in 5 years. The affordability headroom of $-40/mo between current rents and the 30% income threshold is essentially zero, meaning rent increases must be matched by income growth to avoid tenant turnover.
The median income of $56,400 supports a mixed tenant base of young professionals, small families, and long-term renters. 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.
Brookings 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 $1,450/mo, management costs roughly $160/mo. Self-management makes sense if you are local, have fewer than 5 units, and the rent level justifies your time — at $1,450/mo, self-management of a small portfolio saves meaningful dollars but professional management becomes economical at 3-4 units.
