single-family rental rates versus multi-family rental rates

[Brian Kreitz]

If I had a 3 bed 1 bath on both sides of a duplex and a 3 bed 1 bath single-family home in the same neighborhood how different would the rental rates be? I'm assuming you could get more for a single-family verse multi-family? Why exactly is this? I am trying to determine what to set my rental rate at when doing property analysis but a lot of websites / tools for that are geared towards single-family homes.
