Can I check off bought a home , if i'm renting to own?

If you have those expenses of a homeowner, you should check the box. The bought a home box is for the program to know if you will have property tax, mortgage interest, PMI, expenses that come with home ownership. 

A "rent to own" should have a mortgage calculation for the amount of interest you are paying.

These days, very few people actually claim those expenses on the federal, but you may be able on the state.
