I guess I was unclear. Structurally, the house is sound. This is a 50 yr old house that has not been abused, but it certainly has been well used. The old owner just moved into a nursing home, and no undating had been done in at least a couple of decades.
If we wanted, we could live in the house now - and into the indefinite future. However, we wish to make this into the home we enjoy for the next couple of decades. It has exactly the floorplan we want, on the type of lot we want, in the location we want. We should be able to get it for a very good price, and can afford to redo it to our personal preferences.
So the windows all appear to work (well, one sliding door has clearly seen better days) - but they are 50 years old - and aren’t something classic that needs to be saved.
Interior doors are all there and work - but are old and cheap.
No apparent leaks in the roof/major gutter problems presently - just thinking that we might wish to refresh the facad - perhaps replace aluminum siding w/ cedar or composite.
AFAIK, kitchen and baths are fully functional - just ugly and tired as hell.
Rooms all need paint. Trim is nothing special, and has been painted poorly. Suspect the easiest thing will be to simply replace it - which I can do myself. Entire interior needs paint - again, we are happy to do.
Also AFAIK, furnace, water heater, AC all work - but again, I’m expecting they could go out at any time.
So I’m thinking the first thing to do to make it as liveable as possible is to hit the kitchen, then the baths. That will make us look hard at the electric/plumbing. After we move any walls for that, we can do all the floors. Everything else is cosmetic, and can be done at our leisure.
Windows and siding - we’ve had that done before in a house we were living in.
Right now the house is full of an old lady’s junk. Just about the only decorating thing that is of any interest/value is the blue Tiki bar in the family room! gotta figure out how to incorporate that badboy into our vision! 
I guess another thing I’m wondering is, if we are going to be doing quite a bit of work like this, are there any special things you would do now, that you would enjoy having had done later? I dunno - work on the ducts. Upping the elect to 200 amp…
