You want to keep a "life estate" for all those who you want to be able to live there for life. This is a more complex deed, and a more complex decision, than most and probably beyond Avvo. A general attorney with background in real estate and the basics of estate planning should be able to help at a reasonable cost. You can probably find one in the Find a Lawyer function at the bottom of this page.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.
