What method(s) do you use to determine rent for your property?

[Daniel M. Pitta]

I am looking to house hack a SF home or duplex within the next 8-12 months. I'm curious what methods are popular for determining how much to rent out rooms for. I've heard that checking craigslist is effective...I've also read online that an easy rule of thumb is to charge between 0.8-1.1% of the cost of the home, in rent. This seems like the easiest route to go, and very simple to use.
