Summary answer: On a $700,000 home in Manassas with 10% down at today's rates (~6.65%), expect a total monthly payment of roughly $5,180-$5,280 including principal, interest, property taxes, insurance, and PMI. Worth being direct: $700,000 sits above Manassas's own single-family average of $670,000, putting you at the top of the area's realistic range.

Why Manassas's higher city tax rate matters at this price point
Because Manassas's rate ($1.26/$100) is meaningfully higher than nearby Prince William County (~$0.98), the property tax component here runs noticeably higher than an equivalent home just outside city limits.
