If your plans were to buy a house anyway, go for it. If you did not plan on
buying a house, I wouldn't worry about getting a slip until after you are ready to close on your boat. Whatever marina the boat you
purchase is in will most likely allow you a few weeks to pay slip
fees until you find a permanent home. It would be silly to
lease a slip or buy a house for a boat before you have a boat because the hunt for the right boat can take months.
