15-Year vs. 30-Year Mortgage in New Jersey
The choice between a 15-year and 30-year mortgage in New Jersey comes down to monthly cash flow versus total cost. On the $505K median home with 10% down, a 30-year mortgage at 6.5% gives you a total PITI of $4,037/mo. A 15-year mortgage at 6.0% (15-year rates are typically 0.5-0.75% lower) pushes that to $5,000/mo — about $963 more per month. But you save approximately $344K in total interest and own the home free and clear in half the time.
In New Jersey's higher-cost market, the monthly difference between 15 and 30 years is substantial: $963 per month. That is a significant commitment for many New Jersey households, especially first-time buyers already stretching to afford the down payment and closing costs. The 30-year mortgage often makes more practical sense here, preserving monthly flexibility while still building equity. If your income grows over time, you can always make extra principal payments on a 30-year loan to capture some of the interest savings without being locked into the higher payment.
With New Jersey's 2.47% property tax rate adding $1,039/mo to the payment regardless of loan term, the tax component narrows the relative difference between 15 and 30 years. Taxes and insurance are constants in both scenarios — only the principal and interest portion changes. This means the percentage increase from choosing a 15-year term is smaller than it appears from the P&I numbers alone, because taxes and insurance are already a large share of the total in a high-tax state like New Jersey.
Whichever term you choose, the NJHMFA DPA Program program (up to $15,000 forgivable) can ease the upfront burden.
