When looking for a home in Annandale, you might be surprised by the listing prices.

A decent single-family home now easily exceeds $600,000, and homes around $700,000 no longer seem particularly special.

Based on the market trends from Zillow and Redfin for the first half of 2026, you should expect home prices in Annandale to be around $700,000. The location in Northern Virginia, which allows for commuting to Washington DC, along with a well-established Korean community, makes it difficult for prices to drop significantly.

So, how much income do you actually need to buy a $700,000 home?

If we assume a 20% down payment of $140,000, the mortgage would be $560,000. With a fixed interest rate of 6.75% over 30 years, the monthly principal and interest would be about $3,632.

But that's not all.

If we estimate the property tax in Fairfax County at around 1.1%, the property tax for a $700,000 home would be approximately $640 per month.

If we estimate homeowners insurance at about $1,500 annually, that adds another $125 per month.

In total, combining the mortgage principal and interest, property tax, and insurance, you would be looking at about $4,400 per month for housing costs.

If the home has an HOA, the actual burden would be even higher.

So, what should your annual income be? Using the traditional calculation method that limits housing-related costs to about 28% of monthly income, you would need a monthly income of about $15,700, which translates to an annual income of approximately $189,000.

Of course, this doesn't mean that banks strictly apply this criterion. The actual amount you can be approved for can vary based on how much you owe in car loans, student loans, and credit card debt. Conversely, if you have little debt and good credit, different conditions may apply.

Interestingly, Fairfax County itself is known to be a high-income area in the U.S. The median household income is reported to be around $130,000, yet it is still insufficient to purchase a $700,000 home based on the traditional 28% guideline.

This partly explains why many households in Annandale are dual-income. If both spouses earn around $90,000 to $100,000 each, their combined income of $180,000 to $200,000 makes it more realistic to consider a $700,000 home.

On the other hand, if you are a single-income household earning around $100,000 to $130,000, it may be more practical to consider townhomes or condos at a lower price point or to make a larger down payment.

While home prices in Annandale are high, Virginia has the advantage of relatively lower property tax burdens compared to some major metropolitan areas in Texas. When comparing just home prices, it may seem expensive, but when you factor in the annual property taxes, the story changes a bit.

In conclusion, if you were to purchase a $700,000 home in Annandale with a 20% down payment, you could consider a monthly housing cost of about $4,400 and an annual income of roughly $190,000 as a guideline.

Ultimately, the important question is not whether you can buy a $700,000 home, but whether you can comfortably manage over $4,000 in monthly housing costs after the purchase. In Annandale, it's realistic to start with that calculation before looking for a home.
