What to add to the base payment
FHA mortgage insurance. FHA charges an upfront premium of 1.75% of the base loan, usually added to the loan. It also charges an annual premium paid monthly. With 3.5% down on a 30-year loan under $726,200, the annual rate is 0.55% for the life of the loan.
On the $405,000 median with 3.5% down, the upfront premium is about $6,839. That raises the loan to about $397,664 and the payment to about $2,721. The annual premium adds roughly $179 a month in the first year.
Private mortgage insurance. Conventional loans with less than 20% down usually carry PMI. The cost depends on your credit and down payment. You can ask to cancel it when your balance is scheduled to reach 80% of the original value. It ends automatically at 78%.
Property taxes. Start with the last full-year tax bill on the listing and divide by 12. Cook County bills a year behind, and your bill can change once your Homeowner Exemption applies. Our costs guide explains the tax credit at closing.
Insurance and assessments. Add a homeowners insurance quote, and for a condo, the monthly association assessment. Ask what each assessment covers before you compare buildings.
