Rent for my loft at 11th and Folsom was raised in 2012 to $2650. My wife and I moved across the bay to Oakland and now pay $2725 a month all for a house. The loft was then rented for $3300 after we moved out.
1000 sqft loft: $3300 1150 sqft house w/ 40x50 yard and 1 car garage: $2725
But, that isn't in san francisco, but it is within a similar commute distance.
