Round Rock's 0.4% rent-to-price ratio is well below the 1% rule. At median prices of $425,000, the $1,560/mo rent produces only $586/mo in NOI. Investors here need to target below-median properties or pursue value-add strategies to make the numbers work.
At current rates, a 20% down conventional loan ($85K at 7%) would result in approximately $-1,675/mo cash flow — negative at median prices. Larger down payments, seller financing, or buying 15–25% below median are strategies to turn the numbers positive.
Property taxes consume 40% of gross rent here — one of the highest ratios in our dataset. This significantly compresses margins and makes Round Rock a market where tax-conscious underwriting is essential. Every deal should be stress-tested with potential assessment increases.

Round Rock, TX has a population of 138,000 and has been growing at 3.1% annually — well above the national average, signaling strong housing demand from population inflows. The median home price of $425,000 paired with median rents of $1,560/mo produces an estimated cap rate of 1.65%.
Property taxes at 1.74% are notably high and represent a significant drag on cash flow — model this expense carefully, as it can make or break a deal. The vacancy rate of 4.8% is impressively low, indicating tight rental supply and strong tenant demand — favorable for landlords.
At a price-to-income ratio of 5.2x, homes cost about 5.2 times the local median income of $82,400. This moderate ratio indicates a balanced rent-vs-buy market. Home values have appreciated at roughly 3% annually. Steady appreciation means total returns will be primarily cash flow-driven — the more sustainable model for long-term wealth building.
Bottom line: At current median prices, Round Rock is challenging for pure cash flow investing. Consider BRRRR strategies with below-market purchases, or look at neighboring metros with stronger price-to-rent ratios.
