if I filed bankruptcy chapter 7 and my home loan was included in the discharge do I now own the house?

You have a common misunderstanding of what a discharge is and does.  It does NOT remove liens against your property.  Unless you obtained a separate order avoiding the mortgage liens (which you cannot do in a Chapter 7 case), then all the discharge did was remove your obligation to pay on the underlying debt, but the lien against the property remains.  Thus, if you fail to make the required payments on your mortgage, they can exercise whatever rights they have under your state's laws against the property (usually foreclosure). My article on what happens to mortgage debts after discharge may be of interest to you.
