Conforming vs. Jumbo Loans in Arizona — Where the Line Is in 2026
A "Jumbo loan" is just a mortgage above the conforming limit set by the FHFA. In Arizona for 2026, that line is $832,750 for a single-family home — and every Arizona county uses that same baseline, with no high-cost county exception. Anything above $832,750 falls into Jumbo territory and is underwritten to private investor guidelines instead of Fannie / Freddie. Here's exactly what changes when you cross.

The 2026 conforming limit in Arizona
- Single-family: $832,750
- 2-unit: $1,066,000
- 3-unit: $1,288,550
- 4-unit: $1,601,400
- Every Arizona county uses the same $832,750 single-family baseline. No Arizona county carries a high-cost (high-balance) conforming designation, so the Jumbo threshold is the same statewide. Verify against the current FHFA chart if you are buying outside Arizona.
What changes when you cross into Jumbo territory
- Underwriting: Private investor guidelines instead of Fannie / Freddie automated underwriting. More overlays, more file-specific decisions.
- Loan size: Typically up to $3M on standard programs; super Jumbo treatment above $3M.
- FICO floors: Tighter, 660 minimum on most Jumbo programs vs. 620 on conforming.
- Reserves: 6 months of Principal, Interest, Taxes, Insurance, and Association fees or dues (PITIA) at standard amounts, scaling to 12–18 months at $3M+.
- Down payment: 90% LTV available on smaller Jumbos (≤$1.5M); typically 80% LTV at $1.5M–$3M; 70–75% on super Jumbo.
- Qualifying: Often comparable to conforming on strong files. Jumbo guidelines have tightened materially over the last several years.
What stays the same
- Down payment is still equity contribution; closing costs are still 2–4% of loan.
- FHA and VA aren't typically Jumbo (different programs entirely. VA can exceed conforming limits in high-cost counties without becoming "Jumbo").
- Owner-occupancy still drives the the best program fit; second-home and investor pricing tiers exist but at lower LTV.
The split-loan trick (and why it's mostly outdated)
Old strategy: take a conforming first loan up to the limit and a HELOC or piggyback second to bridge to the purchase price. The math used to favor it because conforming pricing was much sharper than Jumbo. That gap has largely closed. Today, a single Jumbo loan often prices better and is operationally simpler than a split.
