If you want to know if your father's home has been lost in a foreclosure, you need to go down to the county recorder's office in the county where his real property is located. Once there, pull up his name and the property's assessor parcel number as well as the common address of the property.Once done, the information retrieved (especially) the property's assessor parcel number should show you in whose name the real property that your father is living in currently is in. If there is a trustee's deed recently recorded on the property that your father is currently living in, most likely the property has been foreclosed upon.If this is the situation, you can contact the entity now holding title to it to see what can be done. Better yet, you should contact a real estate attorney about this situation.Good luck.
