To re-iterate, Daisy, while we own that house, DD lives in it.
The house that we own and live in, is one story, but there is 1 step up from the driveway to a landing in front of the front door, and about 4-5 steps down from the back of the house to the main garden walkway. (2 or so steps down to the patio.) No banisters for those exits/steps, which is why I've been using a cane on the steps. (There is another exit with maybe 6-7 steps that does have railings, but we don't usually use it.)
The rest of the property is of varying levels and safety, gopher tunnels and holes being one hazard.
