Common questions
How much do I need to make to buy a $300,000 house in Illinois?
About $90,079 a year at the 28% front-end ratio, with 20% down and a 6.65% thirty-year fixed. That covers a $2,102 monthly payment: $1,541 principal and interest, $470 property tax and $91 insurance. Lenders who stretch to a 31% ratio would accept roughly $81,362.
What is the monthly payment on a $300,000 house in Illinois?
Roughly $2,102 a month with 20% down and no HOA. With 5% down the payment rises to about $2,557, because the loan is larger and PMI adds around $166 until the balance reaches 80% of value.
How much are property taxes on a $300,000 house in Illinois?
About $470 a month, or $5,640 a year, at the 1.88% effective rate this state averages. County rates vary around that figure, and assessments here track market value rather than being capped.
How much cash do I need up front for a $300,000 house in Illinois?
$60,000 for a 20% down payment, or $15,000 at 5% down. Closing costs typically add 2–5% of the price on top, and lenders will want a couple of months of the $2,102 payment in reserves.
