Do not start out a college you know (or suspect) you cannot afford.
There are dozens of reasons why Northeastern might or might not accept you. If you didn’t get in to Northeastern (is my assumption correct?) then figure out your next best option and let it go. But planning to only stay at College 1 for a few months, then transfer to College 2 with the ultimate goal of getting in to College 3 seems to me like a sure fire way of never settling in, likely needing an extra semester to make up for credits which don’t transfer, etc.
