I love it!
Virtually everything in this market is multistory with basements that raise the entry six or eight steps above grade, which makes me wonder what the Victorians did when they got old or broke a leg.
On the plus side, all these stairs may keep us fit longer, but we're pragmatic enough to think about the problem they present. A ramp or wheelchair lift will get us in the house, if need be. Once in, there's a full bath and bedroom on the first floor, so if one of us were disabled on the short term, we could manage pretty easily. If it were both of us, we'd have to farm out the laundry.
If it were long-term, we'd want to be able to access the second floor. There's a spot where one of those new small-footprint elevators will fit if we decide to go maximal. The less maximal approach would be a chair lift on the stairs, which we know will work because we're told that a previous owner had one. That would get us to the laundry and our bedroom. If the time comes when none of these things work, it will be our cue to find some kind of independent or assisted living situation.
The positive aspect of this house in terms of aging is its location. If we can still get around but aren't able to drive, we can walk to the necessities of life and to public transportation. That has the potential to keep us independent longer, and perhaps as importantly, keep us from being too isolated in our old age.
