My question involves real estate located in the State of: Washington
My Mother and I co-own the home and property she currently resides in. I own the property and half interest of the structures on the property. All land and structures are legally in my name. She lives there rent free except she pays the annual property taxes and Insurance (my name is also on the insurance) on the home.
She wants to be reassured in the form of a legal contract of some sort that she can continue to live in the home until her death or she can no longer care for herself.
What can I do to satisfy her wants but still be in control of my ownership?
