Summary answer: On a $100,000 household income, standard lending guidelines put your realistic purchase price around $300,000–$350,000. Herndon's genuine condo segment, running $250,000-$450,000, lines up well with this income level — a real advantage over pricier neighboring Reston and Ashburn.
I'm Johnny with JQ Real Estate. Let me give you the honest picture of what this budget actually gets you in Herndon.
The math, and why it's genuinely workable here
| Step | Estimate |
|---|---|
| Gross monthly income ($100K/yr) | $8,333 |
| Target housing payment (28% front-end ratio) | ~$2,333/mo |
| Realistic purchase price (10% down, current rates ~6.65%) | ~$300,000–$330,000 |
| Realistic purchase price (VA loan, 0% down) | ~$350,000–$390,000 |
Why Herndon specifically works at this income level
Herndon's median household income runs $118,000-$125,000 in recent readings, meaning this budget sits below the area's typical buyer — but the town's genuine mix of condos and townhomes means real inventory still exists here. Unlike Reston or Ashburn, where entry prices start considerably higher, Herndon's condo stock (median $250,000-$450,000) gives this income level actual, workable options within walking distance of the historic downtown and the Herndon Silver Line Metro station.
What changes your number
- Loan type — a VA loan removes the down payment requirement, meaningfully expanding your range
- Property type — condos are your realistic entry point; townhomes ($400,000-$600,000) require a somewhat higher income
- Second income — even a modest second income meaningfully changes what's reachable here
Don't overlook these added monthly costs
Whatever price point you land on, factor in Fairfax County's standard property tax rate, homeowners insurance, and — if you're looking at a condo — monthly HOA dues, which can run anywhere from $150 to $400+ depending on the building's amenities. These add-ons genuinely affect what payment you're comfortable with, separate from the mortgage itself.
