Thanks for that indepth reply AMN. I'm sure your data will benefit others besides Weeble37. To be honest, it was something I too had thought of, but not for just yet!

What I've been thinking was a retirement village with separate units, rather than a nursing home come hostel, approach. It's something I have to look further into, but something I've been thinking about, just the same.

Just doing some homework about the pros and cons at the moment!
