I urge you to consider seeking legal help to have a Will drawn up.  If the Will is improperly drafted or executed you run the risk of it being challenged.  Generally it can not also be handwritten,  but that depends on the state and circumstances. Also, there is a formal "ceremony" so to speak, in the execution before two witnesses.  And some states have many laws to be aware of: in Florida for example, the law limits to whom you can leave real property. Good luck.
