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.
All figures below are computed from Round Rock's real market medians. Use them as a baseline; override with property-specific numbers in the calculators.
At 1.74% effective rate on the $425,000 median price, the annual tax bill is $7,395 — that's very high (top 15% of US markets) (+64% vs the national average of ~1.06%). Verify the actual assessed value before purchase; sale-triggered reassessments can push the bill higher than the seller's current statement.
If Round Rock continues appreciating at 3%/yr while rents grow at a conservative 3%/yr, cap rate holds roughly steady as price growth outpaces rent. Year-by-year projection at the median:

Same median-priced Round Rock property — different capital structures. All-cash maximizes cap rate. Leverage trades cash flow for higher cash-on-cash return when the spread between cap rate and borrowing cost is positive.
| Scenario | Cash Invested | Monthly Cash Flow | Annual CF | Cash-on-Cash |
|---|---|---|---|---|
| All cash | $425K | $586 | $7,026 | 1.7% |
| 20% down conventional @ 7% | $98K | $-1,675 | $-20,106 | -20.6% |
| 25% down DSCR @ 8.5% | $123K | $-1,866 | $-22,388 | -18.2% |
Properties don't always trade at the median. Lower-priced units typically offer higher cap rates but harder operations; higher-priced properties tend to compress cap rates while attracting better tenants. All-cash assumptions below:
| Tier | Price | Rent/Mo | NOI/Yr | Cap Rate | Monthly CF |
|---|---|---|---|---|---|
| Below median (~75% price) | $319K | $1,326 | $5,781 | 1.8% | $482 |
| At median | $425K | $1,560 | $5,731 | 1.3% | $478 |
| Above median (~125% price) | $531K | $1,794 | $5,681 | 1.1% | $473 |
Cap rate is just one piece. Real estate returns come from four sources: cash flow, appreciation, principal paydown, and tax benefits. Assuming 20% down conventional financing at 7% and a 5-year hold at Round Rock's historical appreciation rate of 3%:
On a $85K down payment, that's a -8.6% total ROI over 5 years (not annualized). Tax benefits from depreciation are additional and depend on your personal tax bracket.

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.
