Great info above. I didn't get any impression of your budget, even though "resale" was one of your criteria. My Admiral and I began looking for a loop boat about 6 years ago while living in Berlin. We wanted shallow draft, single diesel, large rudder, full-displacement for max economy, separate shower, bow thruster, enclosed fly-bridge or raised pilothouse, twin anchors on pulpit, windlass, A/C-heat, high storage capacity, 40 ft. or under length overall, under 15 ft. height with mast down, non-depreciating vessel (or as close to it as we could get), decent machinery spaces, full keel, generator and space for solar, large tankage, range over 1000 mi., minimum outside maintenance, swim platform, layout principally designed for two, fiberglass hull, space for two reclining chairs, good visibility from helm, easy to single hand, quiet.
Budget was under 200K
Here were the final candidates.
Pilgrim 40 1 stateroom, 1 head
Krogen Manatee 36 1 stateroom, 1 head
Willard 40 1 or 2 stateroom, 1 or two head
Willard 36 1 stateroom, 1 head
Hatteras 42 LRC 2 stateroom, 2 head
Endeavour 36 Trawler Cat 3 stateroom, 1 head
PDQ 34 Trawler Cat 2 stateroom, 1 head
Fontaine Pajot 37 Trawler Cat 2 stateroom, 2 head
All these boats had compromises in various things, but met most of the criteria. The additional plus of the catamarans were that they could cruise in the teens, still with decent economy. The downside was that they were bringing more money. If guests are frequent, of course, two heads are polite, and they usually come with two staterooms.
If I was a limber, smaller guy, I'd probably go with the PDQ and pay the extra money. But I'm big and stiff, so the mono-hulls were a bit better for me. Of course, there are other great loop boats out there that I liked even more, but not for under 200.
Looking at "Skinny Dippin" above, I think that is also a very good candidate and exceptional value. Nice layout.
One more thing. If you need space to yourself, consider that all the boats I have listed are good for having multiple "separate" areas by which to enjoy the water. Assuming that you want to be next to your 1st mate every minute could often clash with what she has in mind. For each of you to have a space to be private might be something you'd want to discuss now instead of later.
