Updated 2026 · Based on median market data for Martin, TN
The median monthly rent in Martin, TN is $1,080, translating to $12,960 in annual gross rental income per unit. The rent-to-price ratio is 0.60% — 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 0.60% rent-to-price ratio means that for every $100,000 invested in property, you collect approximately $600/mo in gross rent. The gross rent multiplier of 13.9x means it takes 13.9 years of gross rent to equal the purchase price — a moderate ratio typical of balanced markets.
Renters in Martin spend approximately 24% of the local median household income ($53,744) on rent. This is well below the 30% threshold, suggesting significant headroom for rent increases. The 30% affordability ceiling puts maximum supportable rent at approximately $1,344/mo — a full $264/mo above the current median of $1,080. This gap represents real upside for landlords who invest in property upgrades that justify premium rents.
The vacancy rate in Martin is 5.7%. 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 1.6% annually is actively adding rental demand, creating a tailwind for landlords.
Martin's GRM (price divided by annual rent) is 13.9x. 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 Martin's median GRM, target properties where you can achieve rents above $1,080 through renovations, better marketing, or targeting underserved tenant segments — or buy at a discount to the $180,000 median price. Every point lower on GRM translates to roughly 0.5-0.8% improvement in your cap rate.
At the median rent of $1,080/mo, a single-family rental in Martin generates approximately $12,960 in gross annual income. After accounting for 5.7% vacancy ($739 lost), property taxes of $1,170, insurance (~$720), and maintenance (~$720), the estimated NOI is $9,611 per year, or $801/mo. Adding an 8% management fee ($1,037/yr) reduces investor cash flow further. Before debt service, you are looking at approximately $8,574/yr in landlord net income. Whether this is attractive depends on your total capital invested — at a $36,000 down payment, the unlevered yield on equity from NOI alone is 26.7%.
Rent growth in Martin is driven by the interplay of population growth (1.6%), income growth, and housing supply constraints. With population expanding at 1.6% annually, demand for rental housing is growing faster than most markets can build, which supports above-average rent increases. Projected rent growth of approximately 4% annually would push the current $1,080/mo to $1,215 in 3 years and $1,314 in 5 years. The affordability headroom of $264/mo between current rents and the 30% income threshold provides substantial room for rent increases without pushing tenants into financial stress.
With a median income of $53,744 and affordable home prices ($180,000), many tenants in Martin 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.
Martin 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 $1,080/mo, management costs roughly $119/mo. Self-management makes sense if you are local, have fewer than 5 units, and the rent level justifies your time — at $1,080/mo, self-management of a small portfolio saves meaningful dollars but professional management becomes economical at 3-4 units.
