Summary answer: On a $700,000 home in Herndon with 10% down at today's rates (~6.65%), expect a total monthly payment of roughly $5,070-$5,120 including principal, interest, property taxes, insurance, and PMI. This is a highly realistic scenario for Herndon, sitting right around the area's own median.

| Property tax ($700K home, $1.1225/$100) | ~$655 |
| Homeowners insurance | ~$150 |
| PMI (10% down) | ~$215-$260 |
| Total | ~$5,073-$5,118 |
How this compares if you go the condo route instead
On a $350,000 condo with 10% down, the same math produces a total monthly payment closer to $2,470-$2,590, plus HOA dues typically running $150-$400/month depending on the building's amenities. This is a genuinely different monthly commitment worth weighing against a single-family purchase.
What a VA loan changes here
With $0 down, your principal and interest payment on the same $700,000 home rises somewhat (financing the full amount), but you eliminate PMI entirely and the upfront cash requirement — often netting out to a similar or even lower total monthly payment depending on your specific rate.
What to bring to your lender conversation
Come prepared with your last two years of tax returns, recent pay stubs, and a list of any other debts or assets — the more complete your picture upfront, the faster and more accurate your pre-approval will be. Herndon's genuine mix of condos, townhomes, and single-family homes means your lender should also know which property type you're targeting, since this can affect loan program eligibility and appraisal requirements.
