Well done her and well done you.
We had a blind dog for many years. In terms of caring for them from a "landlords" point of view, I think it will only be a matter of a safe environment. We found that, yes, being predictably tidy was one of the most important things to do. They soon learn to expect an object in a certain place but crash into items left lying around or into furniture/garden furniture/tools that are moved to new positions or left lying around.
Bit like having a toddler too ie. no garden forks left with prongs up to be landed on, deep water fenced (mine ended up a couple of times swimming out into lakes and then not being able to hear the come command and so couldn't work out which way to swim to get out

). Fenced securely from any stock and supervised carefully when introduced to any dogs,cats etc that you may have ..... can't see to read the body language of others so can more easily end up in a fight or hurt. All gates kept closed .... get lost more easily .... sign on your gates to say please close.
My dog came on holidays with us, the park, forests, everywhere and we had 2 toddlers in tow. No real problems or ones that couldn't be solved.
Sure they will be fine once they settle in
