Are my parents ripping me off with this deal that doesn't allow me to build my equity in my home?
You're paying 5.2% 'interest' on the $115K (500 * 12 / 115,000) * 100 but the amount you pay back is not $115K but 75% of the property value at sale. Is that right? A mortgage would have cost about half that rate and the balloon payment would have been fixed - you would pay back $115K at maturity plus you could have sold it whenever you liked As Gnasher729 said, if you consider it to be rent then the situation looks different but the point of buying a house is to avoid paying 'useless' rent, build equity and hopefully make a capital gain I'd speak to a lawyer & possibly an accountant (regarding the numbers)
