A typical Illinois homeowners insurance policy costs about $1,328 a year, or $111 a month, which the calculator includes in the total payment. Premiums vary with the home's replacement cost, location and claims history, so get quotes from several carriers before you close.
How much down payment do I need in Illinois?
Conventional loans allow as little as 3% to 5% down, FHA loans require 3.5%, and VA and USDA loans can be zero down for eligible borrowers. On the median Illinois home, 20% down is $52,660 and avoids PMI; 5% down is $13,165 but adds PMI of about $104 a month until the balance reaches 78% of the price.
Should I choose a 15 year or 30 year mortgage in Illinois?
On the median Illinois home with 20% down, the 30 year payment is about $1,421 a month in principal and interest versus about $1,851 on a 15 year loan at 6.639%. The 30 year loan costs about $301,063 in interest over its life compared with about $122,546 for the 15 year. Choose the 15 year if the higher payment fits comfortably; otherwise take the 30 year and pay extra principal when you can.
What is PITI?
PITI stands for principal, interest, taxes and insurance, the four parts of a typical monthly mortgage payment. Lenders usually collect the tax and insurance portions in an escrow account along with the loan payment, which is why the bill you receive is higher than the principal and interest figure alone. This calculator estimates all four for Illinois, plus HOA dues and PMI when they apply.
What is PMI and when does it go away?
Private mortgage insurance protects the lender if you default and is usually required on conventional loans with less than 20% down. It typically adds 0.3% to 1.5% of the loan amount per year. On most conventional loans it is canceled automatically when the balance reaches 78% of the original purchase price, and you can request cancellation at 80%.
