I would agree with that, my limited personal experience with mid-atlantic beach towns has been either retiree who invites family, multiple pods of a family that co-own a house like you describe, or sort of normal vacation rental for a week-10 days.

And I think because seeing that, my initial suspicion is they really know their target market, or something, and I'm not it. Because the whole "[bought a house on lake Tahoe]...inspired about making the dream of second home ownership possible for more people"

Makes me think "wow, really? that's the narrative pitch?" But tbf I don't know how you go about pitching a second home without sounding like Marie Antoinette.
