Rocknrobin's answer is the best so far, and it is also important to get an eldercare consultation either estate planner or an attorney who really knows your state's Medicaid regs. Estate recovery rules vary somewhat state to state. Basically Medicaid is in the business of providing care but not in the business of preserving inheritances these days...
There is a misconception on the state "taking" the house. The state isn't in the real estate business. Under the description from freqflyer, the house would need to be sold. The state would have a lien against the property. The lien would be paid at the closing table. Then the property could pass free and clear to the buyer.
rcantu, if your name was added to the Deed more than 5 years ago, then Medicaid would take half the value of the house to help pay for whatever care they gave your Dad.
If your name was added within a 5 year time span of applying for Medicaid [or whatever is the limit in your State] then as Pam had mentioned above, Medicaid will consider that a "gift". Then you would need to make up the difference money wise for your Dad's care.
