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.
