I'm looking to make this move in August and some of the advice here won't work for me. For instance, I can't get a reference from a past landlord or a list of past landlords - I'm just graduating college and have lived in on-campus housing my whole time. I'm hoping having a very good credit score and a very good offer letter in hand will solve this issue, but I'm not sure. Additionally, I can't move out mid-month and…
If you can't move in at the beginning of the month, it's not the end of the world. Tons of people in SF move out of their apartments mid-month, and you'll rarely see a shortage of housing inventory for mid-month move-ins. The key is moving in on them quickly and being willing to sign an application or lease on the spot. If all else fails, you can always do a short term sublet or Airbnb from the 15th through the 30th and use that time to find a lease that begins on the 1st.
