Frequently Asked Questions — Jumbo vs Conforming
Do I need 20% down to avoid PMI on a jumbo loan?
No. Cornerstone's Arizona jumbo programs carry no monthly PMI regardless of down payment, including a 10-percent-down option up to roughly $3 million for qualifying borrowers. PMI is a conforming-loan feature avoided by choosing the jumbo product itself, not by reaching a specific down-payment percentage.
Why does the required down payment jump so much right above $832,750?
Below $832,750 you're financing a conforming loan, with standard low-down-payment programs available. The moment your loan amount crosses $832,750, the file underwrites to jumbo guidelines, which carry their own down-payment and credit tiers instead of Fannie Mae or Freddie Mac's.
