Summary answer: On a $100,000 household income, standard lending guidelines put your realistic purchase price around $300,000–$350,000 — which, honestly, falls short of Reston's own median price of roughly $600,000–$640,000. This income level is more realistic for a Reston condo near Town Center (starting around $390,000–$450,000) than for a single-family home here.
I'm Johnny with JQ Real Estate. Let me give you the honest picture of what this budget actually gets you in Reston.
The math, and where it points in Reston
| 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 (with down payment assistance or larger down payment) | ~$350,000–$390,000 |
Why this is a genuine stretch for Reston specifically
With Reston's median sitting at $600,000–$640,000 and even condos starting around $390,000, a $100K income on its own puts you at the very entry point of the local market — realistically pointing toward a smaller condo rather than a townhome or single-family home.
What changes your number
- Down payment size — every additional 5% down meaningfully increases purchasing power
- Second income — if this is a household decision, the math roughly doubles, opening up townhomes and more of Reston's inventory
- Property type — condos near Town Center or Lake Anne get you further than a single-family home at this income level
- Down payment assistance programs — worth exploring given the gap between this income and Reston's median
