Updated 2026 · Based on median market data for Houston, TX
The median monthly rent in Houston, TX is $1,620, translating to $19,440 in annual gross rental income per unit. The rent-to-price ratio is 0.53% — 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 0.53% rent-to-price ratio means that for every $100,000 invested in property, you collect approximately $531/mo in gross rent. The gross rent multiplier of 15.7x means it takes 15.7 years of gross rent to equal the purchase price — a moderate ratio typical of balanced markets.
Renters in Houston spend approximately 33% of the local median household income ($58,200) 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 Houston is 6.4%. 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 1.5% annually is actively adding rental demand, creating a tailwind for landlords.
Houston's GRM (price divided by annual rent) is 15.7x. 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 Houston's median GRM, target properties where you can achieve rents above $1,620 through renovations, better marketing, or targeting underserved tenant segments — or buy at a discount to the $305,000 median price. Every point lower on GRM translates to roughly 0.5-0.8% improvement in your cap rate.
At the median rent of $1,620/mo, a single-family rental in Houston generates approximately $19,440 in gross annual income. After accounting for 6.4% vacancy ($1,244 lost), property taxes of $5,521, insurance (~$1,220), and maintenance (~$1,220), the estimated NOI is $10,235 per year, or $853/mo. Adding an 8% management fee ($1,555/yr) reduces investor cash flow further. Before debt service, you are looking at approximately $8,680/yr in landlord net income. Whether this is attractive depends on your total capital invested — at a $61,000 down payment, the unlevered yield on equity from NOI alone is 16.8%.
Rent growth in Houston is driven by the interplay of population growth (1.5%), income growth, and housing supply constraints. Moderate population growth of 1.5% supports steady rent increases of approximately 2.5% per year. That trajectory takes today's $1,620/mo to $1,745 in 3 years and $1,833 in 5 years. The affordability headroom of $-165/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 $58,200 supports a mixed tenant base of young professionals, small families, and long-term renters. The larger population base of 2,304,580 gives you a deeper tenant pool to draw from, reducing re-leasing time.
Houston is a large enough market to support multiple professional property management companies, giving you negotiating leverage on fees. Expect to pay 8-10% of collected rent for full-service management, with leasing fees of 50-100% of one month's rent for new tenant placement. At $1,620/mo rent, that is $146/mo in management fees. Self-management makes sense if you are local, have fewer than 5 units, and the rent level justifies your time — at $1,620/mo per unit, the income per unit is high enough that professional management is clearly affordable and preserves your time for deal sourcing.
