Summary answer: In most of the country, a jumbo loan kicks in above roughly $766,000–$833,000. In Centreville, that threshold is much higher — because Fairfax County falls within the federally-designated high-cost Washington-Arlington-Alexandria metro area, the 2026 conforming loan limit extends to $1,249,125. That covers essentially all of Centreville's inventory, including the top end of Virginia Run's single-family homes.
I'm Johnny with JQ Real Estate. Let me clear up this commonly misunderstood number.
Why the "jumbo" line sits so much higher here
| Loan Size | Classification in Centreville (2026) |
|---|---|
| Up to $832,750 | Standard conforming |
| $832,751–$1,249,125 | High-balance conforming (still not jumbo) |
| Above $1,249,125 | Jumbo |
What actually changes once you cross into jumbo territory
- Larger down payment typically required — often 10–20% minimum
- Stricter credit and reserve requirements — many jumbo lenders want 6–12 months of payments in reserve
- Rate can run higher or lower than conforming — varies more by lender than expected
- Fewer lender options — not every lender offers jumbo products
Where this actually comes up in Centreville
Even Virginia Run's premium single-family homes, running $700,000 to $1.2 million, stay almost entirely within the high-balance conforming range rather than crossing into true jumbo territory. Jumbo financing is genuinely rare for a typical Centreville purchase — this is one of the few things buyers here don't need to worry much about.
Does this change your strategy?
Given how few Centreville purchases actually cross the $1,249,125 line, most buyers here can plan around standard or high-balance conforming financing without the added complexity of jumbo underwriting.
