You are going to have to identify the property so that someone knows what you are talking about.
Normally, the monthly payment will include PITI, which is Principle, Interest, Taxes and Insurance;
This is called IMPOUNDS and the Lender's way of making sure that you pay your taxes and have insurance on the house. It is a good way to go.
You are going to have to work with a local Realtor for the other questions.
Good luck and may God bless
