1) are you paying down more than $400, if so you are making money, but if you put down a large downpayment you’re not getting a good return m2) do an amortization table at 30 years.

This is not a great return, but not terrible.As others noted, there are other risks, like having the property insured at full replacement or purchase price, or if the option is 100% seller financing with no money down or very little, versus 20% traditional down payment, this can start to move it into a better investment.
