Rob Miller explains jumbo loans in Wisconsin — the conforming loan limit, what makes a loan jumbo, and how the qualification requirements differ.
Rob Miller, Branch Manager at MadCity Home Loans, explains jumbo loans and when Wisconsin buyers need them.
What is a jumbo loan and do I need one in Wisconsin?
A jumbo loan is any mortgage that exceeds the conforming loan limit set by the Federal Housing Finance Agency (FHFA). In 2026, the conforming loan limit for most Wisconsin counties is $806,500. Any loan above that threshold is a jumbo loan.
What Makes Jumbo Loans Different?
Because jumbo loans can't be sold to Fannie Mae or Freddie Mac, lenders hold them on their own books — which means stricter qualification requirements:
- Credit score: Typically 700–720 minimum, with 740+ for the best rates
- Down payment: Usually 10–20% down required; some lenders go as low as 5–10% for strong borrowers
- Reserves: 6–12 months of PITI (principal, interest, taxes, insurance) reserves in liquid assets
- DTI: Usually capped at 43–45%, stricter than conventional
- Documentation: Thorough income documentation required — these loans get fully manually reviewed
Do I Need a Jumbo Loan in Wisconsin?
