... Have thought about the Northwest, perhaps out on the Olympic Peninsula. Also considered down around Maryland/VA area since I have family there. Tough decision after being in only one house for over 30 years.
Don't confuse "house" with "home". A house is 4 walls, ceiling and floors. A home is memories, good and bad. You carry your home with you, always. Remember how happy and proud you felt when you first bought the home? Someday a new homeowner will feel exactly the same way you did, because it will be theirs and they will be just as thrilled.
Now, we love our cottage and have over-improved it ridiculously. We are spending a fortune this summer remodeling the master bedroom. But even if we only get five years of enjoyment out of it, it's worth it to us. But in the end, it's a SFH and we don't want to be burdened with upkeep forever.
We will downsize and move to a CCRC - because if there's one thing we learned from taking care of my MIL, it's that it's better to move
sooner rather than later. Do lots of research; visit different communities, investigate their financial footing, make multiple visits in all seasons.
I love the Olympic Peninsula/PacNW but distances can be difficult. There are only a few major freeways in WA and I-5 is a mess, literally. The little towns are beautiful, but the major medical facilities are mostly in greater Seattle. Getting there in an emergency situation is not ideal. The towns are wonderful for active retirement seniors, but when you get elderly you may have to move again.
Many couples fail to consider what they would/can do if one becomes disabled and then later the other develops partial disability. Because these are small towns, people are helpful, but you don't always have the large pool of labor for in-house assistance. Move from Port Townsend to Port Angeles, and friends can still visit. Move from either town into Seattle, and you'd be lucky to see anybody once a year.
If you are talking about the "real" Olympic Peninsula; e.g., the west coast of WA, it is beautiful but the distances are immense compared to the East Coast. I find the Oregon coast more accessible to urban services, with equally pretty small towns.
I'm NOT saying you shouldn't move there. It's marvelous country! But there are downsides to it - stay a month in winter and you'll see what I mean - and I always think that big moves should be undertaken very carefully. There is a different culture and lifestyle in West Coast vs East Coast. You might find that liberating (I did) or you might find it difficult to 'break in' to established social circles. That's why there's an almost equal number that leave the West, as the numbers that arrive, every year.
So come visit the West in January as well as August (if you haven't already), and do the same for the Maryland area. Remember, many senior communities will let you rent for a few days or a week to do a "try out". Remain resolved to visit at least three or four places so you can compare them; don't get swept away by thinking CCRC #2 is so fabulous compared to #1, that you don't need to look any further! You
do need to look at a third and even a fourth, because although they all provide similar services, they will have different social communities.
Also the contract differences - that "fine print" - is really, really important. As a couple, for example, you need to know how they treat residents when one spouse needs nursing care but the other is still capable of asst. living. CCRCs make their own rules; outside of meeting health & safety standards they are autonomous. Many residents are shocked to find they have little recourse about CCRC decisions, such as moving residents out of an AL unit to skilled nursing.
Those are just a few thoughts off the top of my head. I hope you and your wife have a long and successful retirement together, and best wishes for the future!
