How it is calculated

Principal and interest: loan = price minus down payment, standard fixed-rate payment at the rate and term you pick.
Property tax: price × the town's 2025 effective tax rate ÷ 12. Based on 2025 certified rates; town average, your bill may differ after reassessment.
Insurance: yearly homeowners (or condo) premium ÷ 12, plus flood if you add it.
PMI: not included. With under 20%% down, ask your lender about mortgage insurance.
HOA: only if you enter one.
Commute: the NJ Transit adult monthly pass to NY Penn for the station you pick. Where a bus links to the station, the bus fare is extra.
Total: the sum of the parts, rounded to whole dollars.
