@Matthew Wright Check to make sure your town doesn’t have any zoning restrictions on how many units you can have in one building.

Sometimes condos have stipulations in their deed restrictions that go against doing short term leasing, so I would definitely get your agent or do the research yourself to ensure this isn’t the case at the building you’re looking at.
