Phoenix Jumbo loan 2026 — Maricopa County conforming + Jumbo math
Most Phoenix buyers stay under the 2026 Maricopa conforming limit of $832,750. But for buyers in Scottsdale, Paradise Valley, North Phoenix, parts of Chandler, and Gilbert above that price, Jumbo financing kicks in. Here's the math.
Maricopa conforming vs Jumbo cutoff
| 2026 Maricopa Loan Limit | Amount |
|---|---|
| Conforming baseline | $832,750 |
| FHA limit (high-cost) | $562,350 |
| VA limit (baseline; Jumbo above with full entitlement) | $832,750 |
Above these limits = Jumbo financing required.
Phoenix-area Jumbo lender types
- Portfolio lenders (Cornerstone First Mortgage among them), lend their own money, set their own rules
- Private banks, competitive on highest Jumbo, require relationship
- Specialty Jumbo programs, flexible on income docs
- Conventional Jumbo (Fannie/Freddie above conforming through specialty programs), broad eligibility
Phoenix Jumbo loan-size tiers (2026)
As the loan amount climbs, underwriting gets stricter: larger reserve requirements, tighter LTV caps, and additional eligibility overlays. Here is how Phoenix jumbos generally tier by loan size.
| Loan size | Underwriting tier |
|---|---|
| $832K - $1M | Standard high-balance jumbo |
| $1M - $1.5M | Mid jumbo — added reserve and credit overlays |
| $1.5M - $2.5M | Upper jumbo — stricter underwriting, often 700–720+ FICO |
| $2.5M+ | Super-jumbo — largest reserves, lowest LTV caps, sometimes two appraisals |
When to use VA Jumbo vs conventional Jumbo (for AZ veterans)
Veterans with full entitlement can use VA Jumbo above $832,750:
- VA Jumbo: $0 down + funding fee (waived for 10%+ disability), no monthly mortgage insurance
- Conventional Jumbo: 10-20% down required, no PMI, fewer property-condition overlays than VA
For most AZ veterans, VA Jumbo wins on cash preservation since it needs no down payment. For high-income veterans with substantial savings who prefer to put money down and avoid the funding fee, conventional Jumbo can be the cleaner structure.

Cash-flow planning for Jumbo buyers
A bigger loan means a bigger cash commitment, and on a jumbo file that shows up in three places: the down payment, the reserves, and the carrying costs beyond the loan itself. Take a $1.2M Phoenix home with conventional Jumbo and 20% down. That's a $240K down payment on a $960K loan, plus reserves the lender holds you to after closing.
- Down payment: $240K (20% on a $1.2M home)
- Reserves: 6–12 months of total housing cost in liquid accounts after closing
- Maricopa property tax: roughly 0.51% of assessed value annually
- Homeowner's insurance + any HOA dues, which on premium Phoenix communities can be substantial
