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: expect a 700+ credit score, 10–20% down, full income documentation, and cash reserves.
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, so your banking relationship becomes real negotiating leverage.
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.
Some Michigan lenders offer "high-balance" pricing in the band just above the conforming floor, distinct from true jumbo. Asking whether your loan qualifies as high-balance rather than jumbo can save a quarter point.

Frequently asked questions
When do I need a jumbo loan in Michigan?
When you borrow more than the conforming loan limit. Because Michigan has no high-cost counties, that only happens in its priciest markets — Ann Arbor, Oakland County estates, and lakefront property. Everywhere else, a conventional loan covers the median purchase comfortably.
What credit score do I need for a jumbo loan?
Usually 700 or higher, along with 10–20% down, several months of cash reserves, and full documentation. Jumbo lenders hold the risk themselves, so they underwrite more conservatively than conforming loans — but strong banking relationships can improve both approval odds and pricing.
