As to underwriting, you have income questions since one wage earner (?) may be gone, was there insurance and who is the current owner of the property? Did any rights revert to an heir, not the surviving spouse?
That said, if all things are equal, if your offered rate and terms haven't changed, (sans researching this) I don't believe another disclosure is needed assuming this is still the same application with the survivor.
