Can you elaborate? It depends. Your mortgage monthly payment is usually only principle and interest. However, property taxes and insurance can be collected by you monthly and paid on your behalf in your monthly mortgage billing.
Once you close on a property, your monthly payment will include principle and interest. If you have an escrow, your monthly payment will include a portion of your taxes to be put into escrow and paid later. Depending on your type of financing, your monthly payment could also include PMI.
