I personally would rather be an investor/landlord willing to help than not to, as I have found the ethical approach to what my parents always told me growing up to "always treat others as you'd like to be treated" to be very fruitful in this game of life (and real estate) we all play.

You can play around with a typical amort. pay down in that time period and then plug in a higher interest rate to see what you could do to stay at the same cash flow.
