If you're considering a 270, I'd look instead at a Capri 26. Very similar in layout, much better use of space than the old 27, a big enclosed head, and full queen aft berth. Plus the wide side decks and open transom of the 270.
And there are diesel or outboard versions, and wing or fin.
The thing is, the Capri 26 will literally sail circles around a 270. Fast in light wind, quick to accelerate, stable in heavier wind.
Also you can get it with a tiller, not available on the 270. I prefer a tiller for sailing, plus on the 26 it frees up huge amounts of space in the already large cockpit. And removes the hideous steering box from the aft berth.
If you get the outboard version, it opens up the space under the companionway, allowing more room/easier access to the aft berth. And, they then use the diesel tank behind the aft berth bulkhead as a 2nd, selectable water tank, increasing fresh water capacity by 12 gallons for a total of 27. The gas tank is then located in a cockpit locker outside the cabin.
