need a strategy to repay a down payment

[Nam Nguyen]

My relative is willing to loan me $25,000 for a $100,000 property.  The remaining $75,000 would be on a conventional loan for 30 years.  The property cash flows $200 per month. 

What strategy would you use to repay the original down payment?  I haven’t been able to come up with anything creative other than to borrow from someone else to repay my relative. Let’s assume the down payment was a 0% loan.
