If you have a fixed-rate mortgage, your principal and interest stay the same for the life of the loan. However, property taxes and insurance can increase over time, which may slightly affect your total monthly payment. If you choose an adjustable-rate mortgage, the interest rate can change after the initial fixed period. The key is understanding what type of loan you have and planning accordingly. Most buyers choose fixed-rate loans specifically for long-term stability.
Please consult your Mortgage Advisor for guidance specific to your situation before making changes.
