Recently, I came across a case where someone looking to rent out a single-family home in Burke was overly optimistic about their rental income based solely on market rates, neglecting to account for property taxes and insurance. This situation is not uncommon in the current market.

In Burke's rental market, as of August 2026, the median rent is $3,400, which is an 8% increase from a year ago (Zumper). At the same time, the median home value is around $627,955 (Ownwell, as of April 13), and the effective property tax rate is 1.16%, resulting in an annual tax of about $7,250.

The total return calculated by dividing the annual rental income of $40,800 by the purchase price is 6.50%. While this figure seems decent within Fairfax County, the issue lies in the fact that it does not account for property taxes and insurance.

If we apply the 50% rule for operating expenses, assuming they are half of the rental income, the net operating income would be $20,400 annually, and the cap rate would drop to 3.25%. It's important to note that the property tax of $7,250 already takes up a significant portion of this. Adding landlord insurance could further reduce the net operating income, making the actual return significantly lower than what was initially calculated based solely on rental rates.

If financing is involved, with a 25% down payment and closing costs, the actual investment amount would be around $176,000, borrowing the rest at an interest rate in the 7% range. The annual repayment would exceed the net operating income, resulting in a negative cash-on-cash return. While Burke has a steady demand for single-family home rentals within the Washington DC commuting area, the high purchase prices mean that leveraging increases the burden of initial cash flow.

Just because the effective property tax rate is around 1% doesn't mean the burden is light. In areas like Burke, where the purchase price exceeds $600,000, property taxes can take up a significant portion of annual rental income, so it's crucial to factor in property taxes and insurance first when calculating net operating income. Virginia's property tax relief structure is designed differently than Texas, so families moving from other states should verify actual tax bills through the county tax office.

Burke is also a popular area for Korean families who choose to live there for the school district. An approach that considers both actual residence and long-term holding, rather than pure rental investment, may be more suitable for this area with lower cap rates. For school district ratings, refer to GreatSchools or Virginia Department of Education resources, but be sure to check the assigned school before purchasing.

Recent market trends show that neighborhoods like Burke, which are primarily composed of single-family homes, can experience larger rental rate increases compared to apartment-centric areas. The 8% rise in median rent over the past year can be viewed in this context. However, it's important to note that just because rents are rising doesn't mean cap rates will also increase; if the pace of purchase price increases is faster, cap rates could actually decrease.

From a total return perspective, even if cash-on-cash returns are negative, the principal repayment and appreciation can lead to different outcomes in the long run. However, this calculation is based on the assumption of price appreciation, so it's essential to first confirm whether the current net operating income is manageable.

Burke has a high proportion of single-family homes with quiet residential environments and spacious yards, which tend to retain family tenants for longer periods. The low turnover rate reduces vacancy risk, but the high purchase prices mean that lower cap rates are a trade-off. This case illustrates that failing to include property taxes and insurance in the initial calculations makes it difficult to understand this structure properly. In neighborhoods like Burke, it's safer to not only observe the rising rental rates but also to first obtain property tax bills and insurance estimates before calculating net operating income.
