Frequently Asked Questions — Jumbo Max Purchase
How is a jumbo max purchase price calculated?
Your gross monthly income is multiplied by a DTI ceiling (commonly 43 to 45 percent on a 2026 Arizona jumbo), minus your other monthly debts, to find the maximum monthly payment you qualify for. That payment is then divided by the mortgage-payment factor at your entered rate plus your county's property-tax and insurance rates to back-solve the maximum home price.
Does a bigger down payment raise my max purchase price?
It can. Because you make principal-and-interest payments only on the financed portion, a larger down payment lets the same monthly-payment budget support a higher purchase price. It does not remove the reserve, appraisal, credit, and underwriting constraints that also cap what you can buy, so treat the higher number as a ceiling, not an approval.
What DTI ceiling should I use for an Arizona jumbo loan?
43 percent is a common 2026 jumbo ceiling, though some lenders target 36 percent for the sharpest pricing and others allow up to 45 percent with strong reserves and credit. This calculator lets you test all three.
