To Move Or Not To Move

Every couple of years, I get an urge to move.  I've lived here since 1986.  I go through the same procedure.  Contact some random real estate agent in possible areas in Maryland, ask about available houses that might meet my desires, then give up and stay here.

I'm not doing it for the fun of it.  I analyze things reasonably well.  The equation is that the problems I want to leave behind are just about equal the the time, cost, and trouble of moving.  Staying in place just seems easier.

I keep coming up with lists and evaluating the lists is all subjective.  If they were numbers, the additions and subtractions would come out about "zero".  For example:

1.  I'm getting older so I'd like not to have stairs.  But spread-out 1 floor houses are more expensive.
2.  I'd like a open style house with 3' walls.  But that means everything has to stay clean.
3.  An open style house give more appearance of space.  But then there are few walls to put tall things up against.
4.  My gardening here is shaded too much by neighbors' trees, but a larger open yard costs more.
5.  My D-I-Y home improvement work over the years has not exactly been terrible, but not admirable either.  I can live with it a lot better than I could sell it to someone else.
6.  The things I dislike about the yard would be nice to escape.  But most of them also fixable.
7.  I know this house so intimately.  I can walk around here in the dark.  In a new house, it would take a year of turning on all the lights at night just to find the bathroom.
8.  Speaking of knowing the house, I knew last year that there was a problem with the A/C just by a slight change in the pitch of the sound.
9.  After 27 years, I have found about the best place for EVERYTHING! I can't imagine how long that would take in a new house.
10.  The cats know how not to get lost here.  That stands by itself as seriously important.  On the other hand, I kept Tinkerbelle inside for a month before I let her out on a harness/leash every day for a few weeks and she didn't get lost.
11.  I'm used to this place and the structures.  Like the 2 sheds.  They fit everything perfectly.  But there isn't anything here I can't replicate on a new property.  And a new larger one would be nicer than 2 old ones.
12.  My garage is so tight that I have only 6" on each side as I pull in.  That seems like a lot more than it is.  Naturally, I don't do that fast.  And I've managed to get some white garage paint on every car I've ever owned.  I could live with a larger garage.
13.  Living here 27 years also means I have long-standing relationships with a Dr, a Dentist, a Barber, etc.  I know where every store is.  The butchers and wineshops know me.  One special orders my favorite wine jusy for me.  Giving that up is hard.

But almost all of those statements could be reversed.  A new house means new possibilities for better arrangements.  No stairs would be easier in the coming years.  An open lot would let me apply the things I've learned about gardening to a new space.  I might find that a new house arrangement is much easier to move around in.   There is some excitement in designing new flowerbeds.  The cats might love the extra yard space and new places to explore.  Unlike when moving here, dead broke with my bank account flat-lined, I have money now (not much D-I-Y work needed).  And unlike when I moved here in my first house and didn't recognize the cheap, cheating ways of my builder, I have some experience in evaluating an existing house or especially one being built new. 

There are other issues.  I could have a solar energy roof and a geothermal heating/cooling system.  I could start with extreme energy-efficient appliances.  In short, I could go from 27 years ago to up-to-date all at once, and probably good enough for the rest of my independent life.  At some cost and a lot of effort...

So it's "familiarity" versus "excitement",  "no effort to stay here" versus "much work in moving".

So I'm asking of those of you who have moved and liked the decision, and those of you who have chosen not to moved and liked the decision, what do you think?  What did you like about your decision to move or not move.  Both decisions are valid, and I'm stuck between them.

I don't often ask for help in making my decisions, but I'm really on the bubble and could use some thoughts.
