Rent out to roommates so I employ the "rent by the room" essentially.Pros:insane cash flowif your room offer is much better value than other places to live, tenants will stay awhilea small community can be built when your tenants become friends with eachothernever ending supply of tenants (at least in my area)Cons:CAN BE management intensiveWILL BE management intensive until you gain experience and know how to manageIf you employ this strategy, the BIGGEST risk/liability mitigator is being VERY clear from the start about your expectations and that you will evict if new tenant doesn't follow your rules.With my setup - I furnish the rooms and have all utilities covered. 

The agent will have access to the biggest platform to get the property sold though, the MLS, so forgoing even a cut rate agent will create more of a loss than the agent fees themselves. 

@Jake Baker - That point is probably my biggest consideration.
