How Mortgage Payments Work in Maryland
A standard mortgage payment in Maryland is calculated using the amortization formula:M = P[r(1+r)^n] / [(1+r)^n - 1]
Where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. On a $390K home in Maryland with a 12% down payment at 6.8% over 30 years, your principal and interest payment comes to approximately $2,237/month— not including property taxes or homeowner's insurance.
Maryland's property tax rate of 1.09% adds roughly $354/month to your total housing cost on a $390K home. This rate is near the national average of ~1.1%.
