Summary answer: On a $700,000 home in Lake Ridge with 10% down at today's rates (around 6.65%), expect a total monthly payment of roughly $4,850–$5,150 including principal, interest, property taxes, insurance, and PMI. Worth noting: $700,000 would put you at the very top of Lake Ridge's realistic single-family range.

The full breakdown
| Cost Component | Estimated Monthly Amount |
|---|---|
| Principal & interest (10% down, $630,000 loan, 6.65%) | ~$4,050 |
| Property tax (~$0.98/$100 combined) | ~$572 |
| Homeowners insurance (estimate) | ~$150 |
| PMI (10% down, conventional) | ~$220–$260 |
| Total | ~$4,990–$5,030 |
Why Lake Ridge's lower tax rate helps at this price point
At $0.98 combined per $100, Prince William's rate keeps this component meaningfully lower than the same purchase would cost in Fairfax or Alexandria.
How your down payment changes this
- 20% down — eliminates PMI, saving $220–$260/month
- VA loan, 0% down — no PMI regardless of down payment
