if you apply to yc and get accepted into their program and your startup happens to be physically located in another part of the country, how difficult is it to find a place to work out of and/or a house to rent? or does yc or the yc alumni network help with finding accommodations too.
Finding space to rent is 1/1000th as hard as the rest of starting a startup. Sublets are sometimes announced on the alumni mailing list, and some companies get together to share a big house, but most just use Craigslist.
