Do the math
What would you pay each month for a home in Oak Brook?
A typical home costs more than the typical income allows
We start with a typical home in Oak Brook, worth $903,200, an FHA loan with 3.5% down and the latest average rate (7.18%). That payment would take 53% of the typical household income in Oak Brook, which is $175,870 a year. For that payment to be 28% of income, a household would need to earn about $332,756 a year. Note: at that price the loan is above the FHA limit for DuPage County ($541,287), so FHA would not insure it; the payment is only a reference.
The calculator's FHA and conventional loan limits are those of all of DuPage County.

The option that asks for the least cash to close is Conventional, 20% down, no PMI.
Cash to close = down payment plus 3% of the price in closing costs (example).
Minimum score: FHA requires 580 or higher for the minimum down payment (HUD Handbook 4000.1). * Fannie Mae requires 620 when a loan is underwritten by hand; its automated system has no fixed minimum.
The ITIN row is an example with a rate 1 percentage point higher: ITIN loans follow no federal rule and each lender sets its own down payment and rate. Nothing in this table promises an approval.
