Roommate wanted to share Four BR Two BA house... - $400 - (Fort Pierce, FL)

I am looking for a person or perhaps a couple who wants to share my house. I would like the renters to agree to living Rent FREE in exchange for the responsibilities of taking care my animals/housesitting when I travel. I frequently visit my grandchildren, which is generally a week to ten day trip. I am also planning an extended trip in the spring. The amount you would pay for rent would be prorated. You would have a private bedroom and bath, but basically have full use of the house...kitchen, TELEVISION room, screened porch, front and back yards. I have neighbors, but I am considered "country living". My backyard opens to a lake and Indian river intercoastal is nearby, making for a very quiet, beautiful place to live with nature. You must have a car, as there is no public transportation. The nearest groceries, gas, etc., is approx one mile from my house. Hutchinson Island ocean beaches and mall-type shopping is a twenty minute drive, You must like animals, as I share my house with one dog and 3 cats.
