Sean, stacked storage are also sometimes called boatels...
You saw the early reply to check out Yachtworld.com. Do that, and look at Sea Ray
SUNDANCER models to get an idea about sizes and prices. I mention this specific style because they generally have two main berths, one forward, and one aft roughly underneath the bridge deck
. That lay-out may speak well to your requirement to sleep four. (Sometimes you can even squeeze in a couple small kids
in a dinette that converts to a berth... but then that can get to be work.)
If that idea looks promising, then check out similar layouts in models by Cruisers, Rinker, FourWinns, Silverton, and whatever other brand names I can't remember off-hand...
Confirm specifically with the marina the overall weight, length, and beam they can handle with their lifts.
Given that you envision this as a condo, you probably don't need a model with a generator
... which may simplify things anyway, since gensets are pretty much stuffed in with a shoehorn, often impacts accessibility to maintain or service
other stuff. And that would also bring the cost down.
If you can home in on models that suit, but nothing on yachtworld in your target area (easy purchase) or price range, then local magazines and Craigslist might surface good examples for actual consideration.
Spending much time in these is like living in a cave, unless you have good canvas
over the bridge deck
and maybe the cockpit
, too. A likely boat but without good canvas
is easily fixable, with some extra $$
