I find most landlords aren’t willing to push back the move-in date on a new place more than a couple weeks in SF. So if I find a place to move into in 14 days, I’ll then give my 30 days notice and end up paying double rent for about half a month as you said. I wish that weren’t necessary, as I usually only need a couple days overlap for moving. When I was younger and living paycheck to paycheck, I couldn’t afford the overlap and would have to give notice and then start looking closer to the actual date... very stressful! I’m sure a lot of people have to deal with this.
