How can you say that with such certainty? I moved from Washington, DC to the Bay Area last fall, and my costs were significantly higher than $1000. Even if I cut all the corners, a hypothetical move to Boston would still cost me thousands of dollars.

If I was doing YC for a summer, I wouldn't need to move. I could just fly there with a couple of suitcases and a laptop, but I'd need some way to cover my existing apartment rent. That's a pretty significant expense over 3 months. And I suspect YC is not looking for companies who see the experience just "doing YC for a summer."

You're trying to do it in one step:

1. Move

It's easier to do it in three steps:

1. "Do YC for a summer" 2. Secure more funding 3. Move

My point was all you need to do YC is a plane ticket and your bags, maybe buy a bed and a desk when you get there.

Fair enough. I probably took your comment a bit too literally. $1000 is not enough to move cross-country, but it probably is enough to relocate for three months. :)
