MIL sold to Kerrville about 4 years ago after the FIL died. Sold the ranch in Harper and moved to where here friends were. We were thrilled for her to have access to medical facilities, HEB, etc just a few minutes away vs her living 45 minutes from anything at the ranch.
She had a great place in a 55+ gated community just a half mile north of the Guadalupe. We helped her get settled and were visiting every few months or so and were really impressed w/ how cute, accessible and friendly the downtown was. We loved walking along the river park that has now been destroyed by the floods.
She was only in that place a few years (long enough to renovate it) when she moved out to the Tierra Linda ranch area. She just couldn't get used to living that close to people so she found a house on 5 acres ("it's turnkey!"...she's spent the last 18 months gutting the place). She's about 5 miles from downtown Kerrville now. It does seem to be a very retiree friendly & equipped town. It's not a place we'd ever retire to (no place in Texas fits that mold), but it does have a lot to offer.
