Elder Law question and real estate

[Scott Harper]

A friend has a mother that has gone to assisted living. She has retirement income of $3000.00 a month. Medicare is paying now but eventually may need Medicaid to pay. 

He has a home valued at 200k and her husband passed a few years ago. 

My friend has consulted attorneys and received conflicting answers. 

If he rents her house does all money (approx 1500.00 month)have to go into a trust to protect it so she can still qualify for Medicaid?

Can he sell the house and put money into a trust to protect it from the five year look back for Medicaid?

Has anyone had experience with this? 

What would you suggest (your personal opinion)

Or an attorney who may know.
