There are too many variables to give you a half-accurate answer.
I will however give you two options:
Google: MORTGAGE CALCULATOR; you may find a bunch and you can play with them.
Find a good Title Company and ask the Escrow Officer to make up a hypothetical deal, using $170,000: They will ask you for several other vartiables and give you a hypo HUD1. It will be far more accurate than a mortgage calculator, or I, can do.
Good luck and may God bless
