What is the monthly payment on a $400,000 house in New Jersey?

How much do I need to earn to buy a $400,000 home in New Jersey?
Using the common rule that housing should be no more than 28% of gross income, a $2,799 monthly payment needs an income of about $120,000 a year. Lenders also look at your other debts (debt-to-income ratio).
Does New Jersey have a homestead exemption?
Most states offer some form of homestead exemption or credit that lowers the taxable value of your main home. Check with your New Jersey county assessor; you usually have to apply once after you buy.
How much house can I afford?
A common guideline is to keep your total housing payment (including taxes and insurance) under 28% of your gross monthly income, and all debt payments under 36%. Use the calculator to find a home price whose total monthly payment fits that range.
When does PMI go away?
On conventional loans you can usually request PMI removal once your balance reaches 80% of the original home value, and it is cancelled automatically at 78%. FHA loans have different mortgage insurance rules.
