Renting home to my parent in exchange with childcare

Hi,

Can I rent my rental house to my parent in exchange with taking care of my kids? 

Can I still claim the house as a rental and get the tax advantages?

We can also pay them $1500 monthly for the child care then they pay $1500 rent. Will it cause any problem tax wise? They don't have any other income other than a little pension money that they bring from their country and we take care of their grocery. They've never filed for the tax.
