ARM vs Fixed Rate in New Jersey
With New Jersey's median home at $480,000 and conforming limit at $1,089,300, choosing between an ARM and a fixed-rate mortgage comes down to your time horizon and risk tolerance. New Jersey benefited from NYC out-migration during COVID, pushing suburban prices sharply higher. Bergen, Morris, Monmouth, and Somerset counties carry the highest values and highest tax bills in the state.
When an ARM May Make Sense in New Jersey
- You plan to sell or refinance within 5-7 years
- You're buying in a high-cost New Jersey market where even a small rate reduction meaningfully lowers payments
- Rates are at cyclical highs and expected to fall — ARM initial rates can be 0.5-1% lower than fixed
When Fixed Rates Win in New Jersey
- You plan to stay long-term (10+ years)
- Payment certainty matters more than short-term savings
- New Jersey's property taxes (2.13%, avg $9,476/year) add enough payment variability without adding rate risk
Closing Costs
Either product incurs similar closing costs (~$7,200 in New Jersey). Frequent refinancing to escape an ARM adds these costs repeatedly.
