Are my parents ripping me off with this deal that doesn't allow me to build my equity in my home?
Yes, you are getting shafted. In the end, you will have paid the full price of the condo, but still own only 25% of it. Your parents' stake in the home should decrease as you repay the loan. The way it is now, they're getting 75% of your condo for free!
