A while ago, an investor who requested a consultation mentioned that after purchasing a townhouse in Fairfax, they struggled with communication issues with their tenants. They were unsure how to notify tenants about rent increases and how flexible they should be when tenants paid rent late, lacking clear guidelines and appearing to be lost. It is important to establish operational standards in advance, just as much as calculating the purchase price at the time of acquisition.

The rental prices in Fairfax are $1,955 per month for a one-bedroom and $2,409 per month for a two-bedroom (source: Zumper, as of August 20, 2026). The average across the county is reported to be around $2,375 (source: RentCafe, as of August 2026). There is a silver lining: Virginia state law prevents local governments from enacting rent control ordinances (source: doorloop.com), so unlike some cities in California or New Jersey, there are no legal caps on the amount of rent increase. However, there are still specific regulations regarding notice periods and security deposit handling that need to be confirmed before signing a lease.

Loan conditions are clearly different from those for owner-occupied homes. The down payment ranges from 15% to 25%, and loans become available with a credit score starting at 620, but a score above 740 is needed for favorable interest rates. The interest rates themselves are typically set 0.5 to 0.75 percentage points higher than those for owner-occupied properties (source: Fannie Mae, Freddie Mac investment property loan guidelines). While these conditions may seem like a barrier to entry, they also indicate that there is less speculative buying pressure.

When considering rental income for loan assessments, only 75% of the expected rent is recognized as income. A lease agreement or an appraisal's rent schedule is required as evidence. The 1% rule suggests that if the monthly rent exceeds 1% of the purchase price, the cash flow is likely to be decent. However, it is important to note that in areas like Fairfax, where the purchase prices are high, meeting this criterion can be challenging.

The property tax rate in Fairfax County is about 0.89% of the home value, and the annual property tax for a median-priced home is approximately $4,543 (source: tax-rates.org). While families moving from states with higher property taxes may find this relatively low, it is essential to consider that the absolute amount increases in proportion to the purchase price.

If managing tenants directly feels burdensome, outsourcing to a management company is an option, with fees typically ranging from 8% to 12% of the monthly rent. While hiring a management company saves time, it also reduces profitability, presenting both advantages and disadvantages. Landlord insurance offers broader coverage than standard homeowners insurance but comes with higher premiums. It is common to set aside about 1% of the asset value annually for maintenance costs.

Comparing properties using the cap rate, which is calculated by dividing net operating income by the purchase price, has both pros and cons. Using net operating income after deducting property taxes, insurance, management fees, and vacancy losses provides a more accurate picture than just looking at gross rent, but if vacancy rates or repair costs are overly conservatively estimated, even good properties may appear undervalued. Comparing the cap rates of multiple properties side by side using the same criteria is a way to reduce mistakes.

Families moving from out of state may overlook certain aspects by estimating property taxes or insurance based on their previous locations. If they only consider the favorable aspects, they may end up with a budget that doesn't align later. Conversely, for those just arriving from Korea and looking for their first settlement, there are pros and cons to both renting first to familiarize themselves with the market and purchasing immediately for investment and residence. Depending on visa status and tax residency, the benefits and drawbacks can vary, so it is advisable to consult both immigration experts and tax advisors.

Fairfax is a popular area among Korean families due to its school district. While school ratings can be referenced through GreatSchools or Niche, it is important to verify the assigned school for the specific address before purchasing, as boundaries change frequently. If there are plans to transition to other investment properties in the long term, it is worth noting that a 1031 exchange can defer capital gains tax (source: irs.gov).
