Working with out of state investors as a realtor/investor

[Joel Phillips]

I have a friend who is a realtor, but also does investing on the side.  She is working with a couple out of state investors that are wanting to buy, renovate, sell and hold properties in our local area.  They have contacted her to do all the work while they do the funding.  What is typical to charge an investor for these tasks?  A commission?  a flat fee?  a certain percentage?  hourly rate?  She would be finding these properties, researching them and then using their money to purchase them, being the onsite contact for the properties, possibly working with the contractors, handling paperwork, doing showings, and listing on the back end if they are selling.   Your suggestions are much appreciated!
