Summary answer: On a $100,000 household income, most conventional lending guidelines put you in a comfortable range of roughly $320,000–$400,000, depending on your down payment, debt, and loan type — well below Loudoun County's current median sale price of about $735,000–$753,000. This isn't a knock on your income; it reflects how far ahead Loudoun home prices have run compared to typical wages. VA loan buyers and dual-income households often have more room to stretch than this baseline range.
I'm Johnny with JQ Real Estate. Let me walk you through exactly how lenders get to that number, and what your real options look like.
The quick math lenders actually use
Loudoun County's own housing office uses a simple benchmark: affordable home price is roughly 3 times annual household income. On $100,000, that lands at $300,000 — which lines up closely with a more detailed calculation using standard underwriting guidelines.
Here's the fuller version, using today's mortgage rate (30-year fixed averaging about 6.65% as of late August 2026):
| 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) | ~$320,000–$330,000 |
| Realistic purchase price (VA loan, 0% down, no PMI) | ~$350,000–$400,000 |
That 28% figure — where your total housing payment (principal, interest, taxes, insurance, and PMI/HOA if applicable) stays under 28% of gross monthly income — is the standard conventional lending guideline. Some lenders will go higher if you have little other debt.
Why the gap between $100K income and $735K median price exists
This isn't unique to you — it's the defining affordability issue in Loudoun right now. The county's own 2026 housing data shows median household income of about $166,100 affording roughly $498,300 under standard lending guidelines, while the actual median home sale price sits around $753,000. In plain terms: even the median Loudoun household can't comfortably afford the median Loudoun home under conventional guidelines. A single $100K income is naturally going to land further down the price range, which usually means looking at townhomes, older housing stock, condos, or areas slightly outside the county's hottest micro-markets (Western Loudoun's Round Hill and Purcellville have been running especially hot).
What changes your number
- Down payment size — every extra 5% down meaningfully increases your buying power because it shrinks both the loan and the PMI cost
- Loan type — a VA loan removes PMI and the down payment requirement entirely, which is a real advantage if you're eligible; find out if you can use a VA loan with no money down
- Existing debt — a car payment or student loans directly reduce how much house you qualify for, since lenders look at total debt-to-income, not just housing costs; see how student loan debt affects buying power in NOVA
- Credit score — a higher score doesn't just get you a better rate, it can shift which loan programs are available to you at all; check what credit score you actually need
- Second income — if this is a household decision and there's a second earner, the math above roughly doubles
A realistic path if $320K–$400K doesn't fit what you want
A few options I walk buyers through regularly:
- Widen the search radius — Fredericksburg, Stafford, and parts of Prince William County offer more home for the same budget with a longer commute trade-off
- Consider a townhome or condo — meaningfully lower price point in the same school districts and commute corridors
- Increase the down payment timeline — even 6–12 more months of saving can shift your realistic price range by $30K–$50K
- Explore down payment assistance programs — several exist for first-time Virginia buyers and can close the gap faster than saving alone

These are general guidelines — your real number depends on your specific credit, debt, and down payment.
