How jumbo loans work
A jumbo loan is simply a mortgage larger than the conforming loan limit, so it can't be sold to Fannie Mae or Freddie Mac. Lenders hold these loans on their own books or sell them privately, which means underwriting is stricter.
- Credit: 700+ credit score
- Down payment: 10–20% down
- Documentation: full income documentation
- Reserves: cash reserves
Pricing is relationship-driven
Because banks carry the risk themselves, jumbo pricing is relationship-driven. Institutions with strong deposit bases — Flagstar, Huntington, and private banks — often price aggressively for existing wealth-management clients.
What's different in Michigan
Jumbo territory is geographically concentrated in Michigan. With no high-cost county designation, the conforming limit is the national baseline statewide, so a home only crosses into jumbo pricing in the state's priciest pockets — Ann Arbor, much of Oakland County, and waterfront markets.
