10% down Jumbo loans without PMI in Arizona, what's actually available
Most Jumbo programs require 20% down. A handful of portfolio Jumbo products allow 10% down without Private Mortgage Insurance (PMI) in exchange for tighter underwriting, larger reserve requirements, and stricter credit overlays. They exist; they're not advertised; and they fit specific borrower profiles.
How portfolio Jumbo lenders skip PMI
PMI exists to protect the lender when the borrower has under 20% equity. Portfolio Jumbo programs avoid PMI by holding the loan on the lender's own balance sheet and managing that risk through underwriting overlays — larger reserve requirements, stricter credit minimums, and lower maximum loan amounts — rather than charging a separate monthly PMI premium. Request a Loan Estimate for your scenario to see the full terms.
These programs are held on the lender's balance sheet (not sold to Fannie/Freddie), so guidelines come from the lender's portfolio policy. That's why every lender's overlay is different.
How 10%-down and 20%-down compare on a $1.2M Scottsdale purchase
The real tradeoff is structural, not just a number. Going 10% down keeps $120,000 of cash in your pocket at closing, but it raises the loan amount by the same $120,000 and tightens the file: you'll generally need a stronger credit score, larger reserves, and a lower DTI to qualify. Going 20% down lowers the loan balance, eases the qualifying overlays, and is the most widely available structure. Which one wins depends on how much liquidity you want to keep and how much underwriting room your file has.
| Scenario | Down payment | Loan amount | PMI | Qualifying tradeoff |
|---|---|---|---|---|
| 20% down (standard structure) | $240,000 | $960,000 | None | Widest program access; lighter reserve and credit overlays |
| 10% down, no PMI (portfolio) | $120,000 | $1,080,000 | None | Preserves cash; needs stronger credit, larger reserves, lower DTI |
| 10% down + PMI (rare for Jumbo) | $120,000 | $1,080,000 | Monthly premium | Adds a monthly PMI cost; uncommon in the jumbo market |

Common questions
Can I do 10% down on a $2M Jumbo loan?
Selected programs go to $2M with 10% down. Above $2M, most require 20%–25%. The qualification math gets stricter as loan size climbs.
What if I have RSU or commission income?
Workable. Lenders typically need 24 months of RSU vesting history or 24 months of commission for it to count fully. Bonus income often gets 50% credit until 24 months.
How does a 10%-down Jumbo differ from a 20%-down Jumbo?
The 10%-down structure carries stricter underwriting than the 20%-down equivalent: a higher loan amount, larger reserve requirements, a stronger minimum credit score, and a lower maximum DTI. The exact overlays vary by lender and scenario and are confirmed after file-specific review.
Can I refinance to drop PMI later if my loan does have it?
Yes, once your loan balance reaches 80% LTV (based on current appraised value), you can refinance or request PMI removal. With portfolio Jumbo loans without PMI, this isn't a factor.
