Summary answer: On a $700,000 home in Oakton with 10% down at today's rates (~6.65%), expect a total monthly payment of roughly $5,000-$5,300 including principal, interest, property taxes, insurance, and PMI. Worth being direct: $700,000 sits below Oakton's own median of $775,000-$1,125,000, so this represents a more accessible townhome-tier purchase here.

What a more typical Oakton single-family purchase actually costs
On a $900,000-$1,000,000 home with 10% down, expect a total monthly payment closer to $6,400-$7,100 — a meaningfully different, more realistic number for Oakton's typical single-family buyer.
Getting to know Oakton
Oakton is a residential part of central Fairfax County between Vienna and the City of Fairfax, known for wooded lots and established neighborhoods. Route 123 and I-66 carry drivers, and the Vienna/Fairfax-GMU Metro station on the Orange Line is a short drive away. When you compare homes here, look at how each one fits your daily routine: the drive or transit ride to work, the distance to shopping and parks, and the character of the surrounding streets. Those practical details often matter as much as the house itself.
Comparing loan types for the same price
The same purchase price can produce very different payments depending on the loan. Conventional loans with 20 percent down avoid mortgage insurance, FHA loans include both upfront and monthly premiums, and VA loans have no monthly mortgage insurance but include a funding fee for most borrowers. Comparing these side by side for a Oakton home shows which option leaves you with the payment you're most comfortable with.
