Most people have no idea how much the real number is — property taxes in NJ change everything. This calculator factors them in.
I've helped hundreds of NJ buyers figure out what they could actually afford vs. what the banks said they could. Sometimes those numbers are very different. If you want a real conversation — no pressure — I'm happy to help you think through it.

In New Jersey, four numbers ride together every single month: P&I (the loan itself), property taxes, homeowners insurance, and — if you put down less than 20 percent — private mortgage insurance (PMI). Add HOA or condo dues if you buy in a community with shared amenities.
Property taxes are the piece most buyers underestimate. Typical NJ effective property tax rates run roughly 2.0 to 2.5 percent of assessed value per year — some of the highest in the country. On a $600,000 home, that can mean $12,000 to $15,000 annually, or roughly $1,000 to $1,250 tacked on to your monthly payment before the loan even touches it. Rates vary meaningfully by county and by town: Essex, Union, and parts of Bergen tend to run higher, while some Morris and Somerset communities land closer to the low end. Homeowners insurance in NJ typically runs $1,200 to $2,500 a year for a single-family home. PMI on a conventional loan usually adds about 0.3 to 1.0 percent of the loan amount annually — the calculator above estimates it at roughly 0.5 percent, which is a fair middle ground.
A mortgage payment is only half the story. New Jersey buyers should also budget for closing costs that are not shared by every state:
Most lenders lean on the 28/36 rule: keep housing costs under 28 percent of your gross monthly income, and total debt (housing plus car loans, student loans, credit cards) under 36 percent. Those are ceilings, not targets. Because NJ property taxes are so heavy, the number the bank says you qualify for and the number that lets you sleep at night are often thousands of dollars apart per month.
Down payment strategy matters as much as price. Conventional loans allow as little as 3 to 5 percent down, FHA goes to 3.5 percent, and VA loans (for eligible veterans) can go to zero. Twenty percent removes PMI and usually unlocks better rates. First-time buyers in NJ should look at the NJHMFA (New Jersey Housing and Mortgage Finance Agency) programs — including down payment assistance (DPA) grants and forgivable second mortgages — plus municipal and county-level programs that stack on top.
Private mortgage insurance protects the lender if you default. On a conventional loan, it kicks in whenever your down payment is under 20 percent. You can request PMI removal once your loan-to-value ratio hits 80 percent (either through payments or appreciation), and lenders are required to auto-cancel it at 78 percent LTV based on original value. FHA mortgage insurance follows different rules and often stays for the life of the loan unless you refinance.
New Jersey consistently ranks in the top three nationally for effective property tax rate. Rates are set at the town level, so two homes across a border street can have very different tax bills. When you compare Zillow listings, always check the tax number — a home listed $50,000 cheaper can cost more per month if the taxes are $4,000 higher per year.
No. Most NJ buyers today put down 5 to 15 percent. Twenty percent avoids PMI and can improve your rate, but waiting years to hit 20 percent while home prices climb often costs more than the PMI you were trying to avoid. Run the math both ways — sometimes buying sooner with less down and paying PMI for a few years is the financially smarter move.
A 15-year loan saves enormous interest but roughly doubles the monthly payment. A 30-year gives flexibility — you can always pay extra principal, but you are not required to. Most NJ buyers pick a 30-year for cash-flow safety and prepay when they can.
